When pesticides are used on crops, the following symptoms generally occur when pesticide damage occurs:
1.: This type of pesticide damage mainly manifests on crop leaves, sometimes also on stems or fruit skins.
2. Yellowing: It is manifested in both stem and leaf parts of the plant, with leaf yellowing occurring more frequently, mainly due to pesticide damage that hinders the normal photosynthesis of chlorophyll.
3. Malformation: It can be manifested in the stems, leaves, and roots of the plant. Common deformities include rolled leaves, clusters, swollen roots, malformed ears, malformed fruits, etc.
4. Withering: This type of pesticide damage often manifests as a whole plant, mostly caused by improper use of herbicides.
5. Growth arrest: This type of pesticide damage inhibits the normal growth of crops, causing slow overall growth. Generally, herbicide damage has more or less inhibited crop growth.
6. Infertility: This type of drug damage is caused by improper use of drugs during the reproductive growth period of crops, resulting in infertility.
7. Shedding: This type of pesticide damage is mostly manifested in fruit trees and dicotyledonous plants, with symptoms such as falling leaves, flowers, and fruits.
8. Poor fruit: This type of pesticide damage mainly manifests on the fruit of plants, causing the fruit volume to decrease, the fruit surface to become abnormal, the quality to deteriorate, and affecting its edible value.
