1. Residue-type phytotoxicity This phytotoxicity is characterized by pesticides that do not cause phytotoxicity to the current crop and which remain in the soil after the application of pesticides, and produce phytotoxicity to crops that are more sensitive to diarrhea. For example, the use of Simazine herbicide in corn fields often causes phytotoxicity to crops such as beets, beans and fruit trees. This kind of phytotoxicity appears mostly in the stage of seed germination or seedling stage. Light root tips, coleoptiles and other parts turn brown and rot, affect normal growth, and severely rotten and rotten shoots, and reduce the emergence rate or no seedling emergence. Because this phytotoxicity is easy to confuse with fertilizers and other hazards, it is important to understand the conditions of cultivation and management of the previous crop and the use of pesticides before carrying out the soil test to prevent misdiagnosis.
2. The chronic type of drug injury can not be manifested immediately after the application of the drug injury, and has a certain incubation period, such as obstruction of growth and deterioration of fruit and flavor. Because of this phytotoxicity, it is easy to be confused with other physiological diseases, so the diagnosis can be diagnosed by understanding the occurrence of pests and diseases, the type, amount, area of ​​application, and comparison with plants that are not applied.
3. The acute-type drug injury has the characteristics of rapid occurrence and obvious symptoms, and it usually occurs within a few hours to several days after application. The general performance is: crop leaves appear spots, perforation, agitation, curling, malformation, wither, yellow, chlorosis or bleaching. The victim's specific performance, the performance of the root damage short and thick, root hair is scarce, the root skin becomes yellow or thick brittle, rot, etc.; seed damage, manifested as the seeds can not germinate or slow germination, the majority of this phytotoxicity due to overuse Pesticides or pesticides used for improper seed treatment; plant damage, manifested as falling buds, fruit deformities, smaller, spots, brown fruit rust, fruit drop and so on.
