Technical field
The present invention relates to pesticide field, especially relate to the composition pesticide of a kind of Imidacloprid and acetamiprid water dispersible granules, be mainly used in the disease control of crops, particularly to the control of mango thrips insect pest.
Background technology
Being mixed of China's insecticide mainly concentrates on being mixed between pyrethroid vinegar class and cruel class of organic phosphates, organic phosphor and carbamic acid and the organic phosphates.Single agent kind that Pesticidal mixture made relates to reaches more than 90 kinds, and wherein organic phosphor accounts for major part, secondly is the cruel and carbamic acid vinegar class of pyrethroid, kills being mixed of dragonfly agent and also occupies suitable ratio.This shows that the development of China's complex preparation is very rapid.Composite dose of form accounts for 76.7% mainly based on the binary built agent; The ternary built agent is less, accounts for 23.3%.Studies show that, by rational agriculture chemical compounding, can reduce the selection pressure of each single agent to insect colony, reduce resistance and produce speed, for the colony that produces resistance (it is following to refer generally to medium resistance level), can recover to carry " heterozygote individuality " and the ratio of sensitive individual of resistant gene and sensitive gene, reduce the proportion of resistance individuality in colony, thereby reduce the pesticide resistance degree.Combined use of pesticides can bring many benefits, but is not that any two kinds of agricultural chemicals can be used with, more can not be at will just can be processed into composite dose with two kinds of agricultural chemicals are blended together.Can use just physics, chemistry and the bioactive variation behind the needs further investigation combined use of pesticides with in order to understand which agricultural chemicals.After using with between single agent, usually can produce some chemistry or physical change, may cause bioactive change, these bioactive changes may cause the increase of virulence or reduce.
