The performance of phytotoxicity varies depending on the type of crop, the characteristics of the agent, the dosage and the method of application. It can be divided into the following types:
Growth stagnant or even withered death, such as pesticide dressing or herbicide for soil treatment to delay emergence or reduce emergence rate; misuse of herbicides during crop growth season, whether stem or leaf spray or soil treatment cause plant yellowing, withering .
Burns stem and leaf tissue. For example, leaves are withered, withered, and burnt edges, etc., which occur mostly on the young tissues of broad-leaved plants, and are prone to occur when using emulsions. Damage to local cells on leaves and fruits may also cause spots of different colors, reducing the quality of vegetables and fruits.
Malformations, including leaf rolling, shrinking, clumping, root swelling, chicken roots, deformed ears (fruit) and so on. For example, in the wheat booting stage, the hormonal herbicide 24-d-butyl ester is used to cause the deformed ear; the tomato is stained with the malformed fruit.
Greening. If the chloroplast is destroyed by using the genus and urea herbicides, the yellowing and whitening of the young leaves will be manifested, and the leaves or fruits will fall off or the leaves and tender shoots will be burned out later.
