At present, the world’s population is increasing and the area of arable land is gradually decreasing. In order to meet people’s demand for food, in addition to trying our best to increase grain yield, we must also minimize the loss caused by non-human factors such as diseases, insects, and weeds. On the one hand, in order to meet the increasing living standards of mankind, it is necessary to increase the cultivation of fruits and vegetables. It is inevitable that food, vegetables and fruits will have diseases during the growth process. Therefore, as an important class of pesticides, fungicides have a broad market. Although there are already fungicides such as pyrroles and amide methoxyacrylates that have come out and played an important role, the ever-expanding fungicides market still expects the development of new, high-efficiency, low-toxic and environmentally friendly chemical fungicides.
New use of triazine derivatives as fungicides. The triazine derivatives provided by the present invention, such as Cybutryne Irgarol, Irgarol 1051, etc. They are all have good bactericidal activity, at a dose of 50mg/L, against melon anthracnose (Colltorichumlagenarium), rice sheath blight solani), cucumber gray mold (Botrytis cinerea), wheat head blight (Gibberella zeae), tomato early blight (Alernaria solani) and apple scab (Venturiainaequalis) have bactericidal activity. It can be used to prepare pesticide fungicides, has low toxicity, does not harm crops, is environmentally friendly, and has broad application prospects in the field of pesticide fungicides.
