A compound composition and preparation containing mesyconazole and pentadophos

Abstract

The invention provides a bactericidal composition containing 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and a preparation containing 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole, which are mainly used for controlling bacterial diseases and virus diseases of various crops. The active ingredients of the compound composition provided by the invention are 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole; and the weight ratio of 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole to Dufulin is (20-1):(1-20). The total weight of the composition containing 2-p-fluorophenyl-5-methylsulfonyl-1,3,4-oxadiazole and Dufulin accounts for 0.1-90 percent of the weight of the preparation. The compound composition can be prepared into preparations such as wettable power, water dispersible granules, a water emulsion, a suspending agent and a seed coating agent. When the compound composition provided by the invention is used, the two active ingredients always keep favorable compound stability and have obvious supplementary and synergistic effects within a certain matching range; and compared with each of the active ingredients for controlling crop diseases, the compound composition enlarges the controlling spectrum, slows down the generation of pesticide resistance, obviously improves the efficacy, reduces the dosage of each of the active ingredients and the application times, better guarantees the agricultural safety production and protects the ecological environment.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a compound composition and preparation containing mesylconazole and chlorfluphos. Background technique [0002] In recent years, the changes in the farming system and planting mode of my country's agricultural production have led to new changes in the law of disease occurrence on the one hand: the intensification, scale and specialization of agricultural production in my country have become more and more obvious, and the same or similar crops have been continuously Pieces, planted year after year, resulting in the occurrence of various diseases and insect pests showing an increasing trend year by year. Especially some systemic infection and destructive diseases, such as rice, corn and wheat virus diseases in my country are serious, bacterial wilt of melons and solanaceous vegetables, virus diseases and fusarium wilt of various crops, etc. The occurrence area is also increasing ...

Problems solved by technology

At the same time, because of the lack of effective chemical control agents, huge economic losses are caused

On the other hand, it also leads to the emergence of some new diseases. For example, the southern rice black-streaked dwarf disease, as a sudden new disease in recent years, has spread rapidly in the main rice areas of the country. 1.13 million hectares, the infestation of this disease can cause serious yield loss, or even a large area of ​​crop failure, so it is necessary to develop a compound composition that can efficiently control various diseases
