1. Cruciferous Vegetables (Chinese Cabbage, Cabbage, Radish, Broccoli, etc.)​

Target Pests: Pieris rapae (Cabbage White Butterfly Larvae), Plutella xylostella (Diamondback Moth), Spodoptera exigua (Beet Armyworm), Spodoptera litura (Oriental Leafworm Moth), Hellula undalis (Cabbage Webworm)​

①Application Timing: Apply the pesticide when the pest larvae are in the 3rd instar or earlier (smaller body size, weak resistance, and no massive feeding damage yet), or when pest egg hatching is first observed in the field. Apply once every 7-10 days, for 2-3 consecutive applications. Re-spray if it rains after application.​

②Formulations and Dosages:​

16000IU/mg WP: 100-150 grams per mu, mixed with 30-40 kilograms of water (increase to 150-200 grams per mu if the pest population density in the field is high);​

32000IU/mg WP: 50-80 grams per mu, mixed with 30-40 kilograms of water (adjust to 80-100 grams per mu for dense pest populations);​

50000IU/mg WP: 30-50 grams per mu, mixed with 30-40 kilograms of water (adjust to 50-60 grams per mu for dense pest populations).​

Operation Points: When spraying, focus on the undersides of vegetable leaves, heart leaves, and leaf axils (areas where pests often gather to feed). Ensure uniform coverage of the pesticide solution and avoid missing any areas.​

2. Gramineous Crops (Rice, Corn, Wheat, etc.)​

(1) Rice​

①Target Pests: Cnaphalocrocis medinalis (Rice Leaf Roller), Chilo suppressalis (Asiatic Rice Borer), Scirpophaga incertulas (Yellow Stem Borer), Parnara guttata (Rice Skipper)​

④Operation Points: Spray gently to avoid the pesticide solution from impacting and causing petal drop. Focus on spraying the undersides of leaves and the heart leaves.​

II. General Usage Precautions​

1.Pesticide Solution Preparation: Before use, first mix the wettable powder with a small amount of clean water to form a paste ("mother solution"). Stir evenly, then add the remaining water and continue stirring until there are no particles. This avoids uneven pesticide solution, which may affect the efficacy. Do not mix with alkaline pesticides (such as Bordeaux mixture, lime-sulfur mixture). It can be mixed with acidic/neutral pesticides or foliar fertilizers (such as potassium dihydrogen phosphate) to enhance efficacy.​

2.Application Time: Choose to apply in the morning before 9 a.m., in the afternoon after 5 p.m., or on cloudy days. Avoid high-temperature periods (temperature exceeding 30°C), strong sunlight periods (the pesticide solution is prone to decomposition), and rainy days (the pesticide solution is prone to loss). If it rains within 4 hours after application, re-spray is required.​

3.Safety Protection: Wear protective clothing, masks, and gloves during application to avoid contact of the pesticide solution with the skin, mouth, and nose. Do not eat, drink, or smoke during application. Wash hands, face, and clothes immediately after application.​

4.Environmental Safety: It is sensitive to fish, bees, and silkworms. Keep away from fish ponds, beehives, and mulberry fields during application to avoid pesticide solution drift to these areas. Do not pour the remaining pesticide solution randomly; it should be properly disposed of (e.g., diluted and sprayed on non-sensitive crops). Empty pesticide bags should be incinerated or buried deeply, not discarded randomly.​

5.Storage and Shelf Life: Store in a cool, dry, and well-ventilated place. Avoid direct sunlight and access by children and pets. The shelf life of different formulations is usually 2 years. Once opened, use it as soon as possible to avoid moisture and caking (caked products cannot be used).

6.Resistance Management: To delay the development of pest resistance, it is recommended to alternate use with insecticides of other mechanisms of action (such as emamectin benzoate, chlorantraniliprole). Do not use it more than 3 times a year, and avoid long-term single use.

As a microbial-derived low-toxicity insecticide, Bacillus Thuringiensis (Bt) has three mainstream wettable powder (WP) formulations (50000IU/mg WP, 16000IU/mg WP, and 32000IU/mg WP) that are applicable to a wide range of crop types. It can achieve efficient control of various pests on different crops, with the specific application scope as follows:​

I. Cruciferous Vegetables​

It covers common crops such as Chinese cabbage, cabbage, radish, broccoli, cauliflower, rapeseed, and mustard. It is mainly used to control core pests on these crops, including Pieris rapae (the main leaf-eating pest of Chinese cabbage, cabbage, etc.), Plutella xylostella (commonly known as "silk worm," which severely damages the leaves and tender stems of cruciferous vegetables), Spodoptera exigua (larvae feed on leaves to form notches or holes and also gnaw on tender fruits), Spodoptera litura (a voracious pest that can gnaw on leaves over a large area), and Hellula undalis (larvae bore into tender stems and heart leaves, causing plant wilting). It can effectively reduce the impact of these pests on crop growth and yield.​

II. Gramineous Crops​

1. Rice​

Applicable to various rice varieties such as early rice, late rice, and medium rice, it can control major pests during the rice growth cycle, such as Cnaphalocrocis medinalis (larvae roll leaves and feed on mesophyll, affecting photosynthesis), Chilo suppressalis (bores into stems, causing dead heart seedlings and dead booting panicles), Scirpophaga incertulas (exclusively harms rice, causing dead hearts and white panicles), and Parnara guttata (larvae tie leaves into bundles and feed on leaves). It ensures the normal growth of rice during key growth stages such as tillering, booting, and grain filling.​

2. Corn​

Applicable to varieties such as common corn, sweet corn, and waxy corn, it targets two pests that pose significant threats to corn yield: Ostrinia furnacalis (bores into stems, tassels, and ears, affecting nutrient transport) and Mythimna separata (larvae voraciously feed on leaves, and in severe cases, can eat leaves completely). It effectively reduces the damage rate of these pests and avoids problems such as plant lodging and poor ear development.​

3. Wheat​

Applicable to winter wheat and spring wheat, it mainly controls Mythimna separata (voraciously feeds on leaves, affecting wheat jointing and grain filling) and Sitotroga cerealella (larvae bore into wheat grains, reducing wheat quality and yield) on wheat. It also has a certain inhibitory effect on occasional secondary Lepidopteran pests in wheat fields, helping wheat complete its growth cycle smoothly.​

III. Cash Crops​

1. Cotton​

Applicable to cotton varieties such as upland cotton and sea-island cotton, it focuses on controlling Helicoverpa armigera (bores into buds, flowers, and bolls, causing boll abscission), Pectinophora gossypiella (bores into cotton bolls, damaging cotton lint), and Anomis flava (larvae feed on leaves, affecting cotton photosynthesis and boll setting). It reduces yield losses of cotton caused by pest damage and ensures cotton lint quality.​

2. Tea​

Applicable to various tea plantations such as green tea, black tea, and oolong tea, it targets Euproctis pseudoconspersa (larvae gather to feed on leaves, and in severe cases, leaves are completely eaten) and Ectropis obliqua (commonly known as "arching worm," larvae feed on leaves to form straight notches). It also has an auxiliary control effect on Empoasca vitis (a piercing-sucking pest that affects tea quality). With low residue after application, it meets the requirements for green tea production.​

3. Fruit Trees​

Covering a variety of fruit trees such as apples, pears, peaches, citrus, cherries, plums, and apricots, it mainly controls various pests on fruit trees, including fruit borers (e.g., Carposina sasakii and Grapholita molesta, whose larvae bore into fruits, causing fruit rot and quality degradation), leaf rollers (e.g., Adoxophyes orana and Adoxophyes cyrtosema, whose larvae roll leaves to feed and also gnaw on fruit peels), and slug caterpillars (e.g., Monema flavescens and Parasa consocia, whose larvae feed on leaves and whose body hairs are toxic and easily cause discomfort to humans). It protects the normal growth of fruit tree leaves and fruits and improves the commercial rate of fruits.​

4. Soybeans​

Applicable to varieties such as spring soybeans, summer soybeans, and autumn soybeans, it can control Etiella zinckenella (larvae bore into soybean pods and feed on beans), Plusia agnata (larvae feed on leaves to form holes or notches), and Leguminivora glycinivorella (bores into soybean pods, affecting soybean yield and quality) in soybean fields. It reduces the interference of pests on soybean pod setting and grain filling.​

IV. Other Specialized Crops​

1. Chinese Chives​

Targeting Bradysia odoriphaga (chive maggot, larva of the chive gnat), a severe pest in Chinese chive cultivation that bores into chive bulbs and pseudostems, causing plants to turn yellow and wilt. It is one of the core insecticides for controlling chive maggots in green Chinese chive cultivation, which can effectively reduce the use of chemical pesticides and ensure the food safety of Chinese chives.​

2. Asparagus​

Applicable to different growth stages of asparagus, it mainly controls Papaipema nebris (larvae feed on asparagus spears and leaves, affecting the commercial value of asparagus) and Xylena exsoleta (larvae bore into stems, causing plant wilting). It protects the normal growth of asparagus spears and reduces the impact of pests on asparagus yield.​

3. Flowers​

Covering common ornamental flowers such as roses, chrysanthemums, peonies, lilies, and Salvia splendens, it can control Spodoptera litura (larvae voraciously feed on leaves and petals), Pieris rapae (feeds on leaves, damaging the appearance of plants), and aphids (auxiliary control to reduce leaf deformity caused by piercing-sucking damage). It ensures that flower leaves remain green and flowers bloom normally, improving ornamental value.​

In addition, this insecticide also has a certain control effect on root-knot nematodes (e.g., parasitic nematodes on the roots of crops such as tomatoes and cucumbers), chive maggots (in addition to Chinese chives, it also controls similar pests on allium crops such as onions and garlic), and mosquito larvae (occasional mosquito larvae in rice fields and waterlogged areas). This further expands its application scenarios, making it suitable for green agricultural product bases, organic agricultural product bases, and conventional agricultural production areas, meeting the pest control needs under different planting requirements.

I. Pesticide Application Safety​

①Personal Protection Requirements: Before applying the pesticide, wear complete protective equipment, including long-sleeved protective clothing, non-slip gloves, medical masks (or gas masks), and goggles, to prevent the pesticide solution from contacting the skin and mucous membranes (such as the mouth, nose, and eyes); during the application process, eating, drinking, and smoking are prohibited to prevent the pesticide solution from entering the human body through the mouth; after application, immediately rinse exposed parts such as hands, face, and neck with clean water, replace and wash the clothing worn during application, and dry it in a well-ventilated place.​

②Taboos for Special Groups: Pregnant women, lactating women, children, and people with allergic constitutions are prohibited from participating in pesticide application operations; if the applicator experiences discomfort such as dizziness, nausea, skin itching, or difficulty breathing during operation, they must immediately stop applying the pesticide, move to a well-ventilated and cool place, rinse the contact area with a large amount of clean water, and seek medical attention promptly if the symptoms are severe, and inform the doctor of the composition of the pesticide used.​

③Warning for Application Areas: Before application, set up obvious warning signs (such as "Pesticide Application in Progress, No Entry") around the farmland to prohibit irrelevant personnel, livestock, and poultry from entering the application area; after application, wait until the pesticide solution is completely dry (usually 4-6 hours, depending on the weather) before allowing personnel to enter the field for other agricultural operations to avoid the risk of contact with residual pesticide solution.​

II. Environmental and Ecological Protection​

①Avoidance of Sensitive Organisms: This pesticide is sensitive to organisms such as bees, silkworms, and fish. When applying the pesticide, keep away from beekeeping farms (distance not less than 500 meters), mulberry gardens (distance not less than 300 meters), and water areas such as fish ponds, rivers, and reservoirs (distance not less than 200 meters); if there are the above-mentioned sensitive areas around the farmland, choose windless or light wind weather for application to avoid pesticide solution drift; when applying pesticide to flowering crops, avoid the bee foraging period (9:00 a.m. to 4:00 p.m.) to reduce the impact on pollinating insects.​

②Protection of Soil and Water Sources: It is prohibited to directly dump the remaining pesticide solution and the wastewater from cleaning pesticide application equipment into the soil, rivers, ditches, or wells. Instead, the solution should be diluted and sprayed on non-sensitive crop fields (such as wasteland and non-edible crop fields); empty pesticide bags and bottles should be collected centrally, treated by incineration or deep burial (depth not less than 50 centimeters), and must not be randomly discarded in the field, on the roadside, or near water sources to prevent environmental pollution.​

③Protection of Natural Enemies: Bacillus Thuringiensis is safe for natural enemies of pests such as ladybugs, lacewings, and parasitic wasps. There is no need to deliberately avoid the activity areas of natural enemies during application to exert the synergistic pest control effect of natural enemies and the pesticide. However, excessive application during the period when natural enemies gather in large numbers (such as the ladybug spawning period) should be avoided to maintain the ecological balance in the field.​

III. Key Points for Ensuring Pesticide Efficacy​

①Grasping the Application Timing: The pesticide should be applied when the pest larvae are in the 3rd instar or earlier. At this stage, the pests have weak resistance and are active in feeding, so the pesticide can take effect quickly through stomach toxicity; if the pests have entered the older instar stage (4th instar or above), the pesticide dosage should be appropriately increased, and the application interval should be shortened (adjusted from 7-10 days to 5-7 days) to ensure efficacy; avoid applying the pesticide in high-temperature and strong sunlight (temperature exceeding 30°C, 12:00 noon to 2:00 p.m.) or rainy days. High temperature will accelerate the decomposition of the pesticide, and rainy days will cause the loss of the pesticide solution. If it rains within 4 hours after application, re-spray in a timely manner.​

②Standards for Pesticide Solution Preparation: Before preparation, check the status of the pesticide. If the wettable powder is caked (there are still hard particles after being crushed by hand), it cannot be used; during preparation, first mix the pesticide with a small amount of clean water to make a paste-like mother solution, stir it evenly, then add the remaining amount of water, and continue stirring for 3-5 minutes to ensure that the pesticide solution has no particles and uniform concentration, avoiding local crop phytotoxicity or insufficient local efficacy due to uneven concentration; it cannot be mixed with alkaline pesticides (such as Bordeaux mixture, lime-sulfur mixture, and copper hydroxide), but can be mixed with acidic and neutral pesticides (such as emamectin benzoate and imidacloprid) or foliar fertilizers (such as potassium dihydrogen phosphate and amino acid fertilizers). After mixing, it should be used immediately and cannot be left for a long time.​

③Resistance Management: To delay the development of pest resistance to the pesticide, avoid long-term and single use of this pesticide. It is recommended to alternate it with insecticides with other modes of action (for example, replace with chlorantraniliprole or indoxacarb once after using Bacillus Thuringiensis twice); the number of applications in the same field should not exceed 3 times a year. At the same time, combine with agricultural control (such as cleaning the field and crop rotation) and physical control (such as trapping and killing with insecticidal lamps) to build a comprehensive pest control system.​

IV. Storage and Usage Management​

①Storage Condition Requirements: The pesticide should be stored in a cool, dry, and well-ventilated warehouse, with the temperature controlled at 5-25°C and the relative humidity not exceeding 70%, avoiding direct sunlight and proximity to fire sources or heat sources (such as stoves and radiators); during storage, place the pesticide at a high place out of the reach of children and pets, and store it separately from food, seeds, feed, chemical fertilizers, and other items to prevent confusion or pollution.​

②Shelf Life and Management After Opening: The shelf life of unopened pesticides is usually 2 years, and they must be used within the shelf life; after opening the pesticide package, it should be sealed immediately and placed in the original package to avoid moisture and caking. It is recommended to use up the opened pesticide within 1 month. After more than 1 month, check the status of the pesticide. If it is damp or discolored, it cannot be used.​

③Cleaning Requirements for Pesticide Application Equipment: After the application, clean the sprayer, measuring cup, stirring rod, and other pesticide application equipment in a timely manner. First rinse with clean water 3-4 times, then soak in a 5% oxalic acid solution for 10 minutes, and finally rinse thoroughly with clean water and dry before storage; if the equipment has been used to spray other pesticides, it must be thoroughly cleaned before being used to spray Bacillus Thuringiensis to prevent chemical reactions caused by the mixture of different pesticides, which may affect efficacy or cause phytotoxicity.​

V. Other Matters Needing Attention​

①Crop Safety: This pesticide is safe for most crops, but some sensitive crops (such as broccoli seedlings among cruciferous vegetables and pea seedlings among leguminous crops) may show slight leaf yellowing when the pesticide dosage is too high (exceeding 1.5 times the recommended dosage) under high-temperature and high-humidity conditions. It is necessary to test the pesticide on a small area to ensure no phytotoxicity before applying it on a large area; if phytotoxicity occurs accidentally, immediately spray clean water to rinse the leaves and spray foliar fertilizers (such as brassinolide) to alleviate the damage.​

②Emergency Treatment Measures: If the pesticide solution accidentally splashes into the eyes, immediately rinse with a large amount of clean water for at least 15 minutes, and keep turning the eyes during rinsing. Seek medical attention if necessary; if the pesticide solution is accidentally ingested, immediately induce vomiting (stimulate the pharynx with fingers or chopsticks) and seek medical attention with the pesticide package. Do not take drugs by yourself; if the pesticide application equipment leaks, use dry sand to absorb the leaked pesticide solution, and treat the absorbed sand as hazardous waste. Do not use it for farmland fertilization.
