Abstract
The invention discloses a composition for killing fungus and bacterium, pesticide and application. The composition consists of metalaxyl and cuppric nonyl phenolsulfonate by weight ratio of 1:50-50:1, preferably, 1:25-25:1. The composition, as an effective ingredient, and auxiliary ingredients capable of being accepted in the pesticide, jointly make up a corresponding pesticide for sterilizing. Test results show that the composition for sterilizing and the effective ingredients in the pesticide can perform obvious synergistic effect, can be used for the preventive treatments of tomato late blight, potato late blight, pepper phytophthora blight and melon downy mildew and on the like, can effectively reduce the application dose in each ingredient, is in favour of delaying the development of plant resistance to drugs, prolongs the lasting period, extends the preventive treatment application scope and has obvious promotional value.
Description
technical field [0001] The invention relates to a fungicide / bacteria composition, in particular to a fungicide / bacteria composition composed of metalaxyl and nonylcopper, the corresponding pesticide and its application in agricultural disease control. Background technique [0002] Tomato late blight is one of the important diseases in the process of tomato planting, and it is seriously harmful in years with continuous rainy weather. When the disease is severe, the stems will rot, the plants will wilt and the fruits will turn brown, which will affect the yield. Potato Late Bright is also a devastating fungal disease that causes potato stem and leaf death and tuber rot. Currently commonly used prevention and control drugs as long as there are azoxystrobin, metalaxyl, mancozeb, chlorothalonil and so on. [0003] Metalaxyl is a high-efficiency systemic fungicide with a structure shown in formula (I) and has protective and therapeutic effects. It can be quickly absorbed by pl...
