Description
Technical field
The present invention relates to technical field of pesticide, particularly relating to a kind of Pesticidal combination containing capillary and Bassa, for preventing and treating agricultural chemicals insect, being particularly applied to the control of rice fulgorid, thrips.
Background technology
Capillary, english common name: chlorfenapyr, it is new pyrrole compounds, act on the mitochondria of insect bodies inner cell, worked by the mixed-functional oxidase in insect bodies, main suppression adenosine diphosphate (ADP) is to the conversion of adenosine triphosphate (ATP), and adenosine triphosphate stored cells maintains the necessary energy of its vital functions.This medical instrument has stomach toxicity and action of contace poison.Strong in blade face permeability, there is certain systemic action, and have the advantages that insecticidal spectrum is wide, preventive effect is high, holding effect is long, safe, effectively can prevent and treat aphid, thrips, diamond-back moth, aleyrodid etc. on vegetables, cotton.Its molecular structural formula is:
Bassa, English name: Fenobucarb, belongs to carbamate insecticide, has stronger action of contace poison, have stomach poison function concurrently, quick-acting, but the longevity of residure is shorter.Main control rice fulgorid, thrips, aphid etc.Its molecular structural formula is:
At present, agricultural chemicals does the Main Means application of agricultural pests widely as chemical control.But the agricultural chemicals of Long-Time Service single variety, easily impels insect to produce certain resistance, peasant household is often through adopting the consumption mode increasing the weight of agricultural chemicals for this reason, to reach the object eliminated destructive insects.But adopt and just also exist in this way, larger pollution and the problem of residue of pesticide are caused to environment, also indirectly improve the drug cost of peasant household simultaneously.There is not been reported for the complex composition of current capillary and Bassa.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Pesticidal combination containing capillary and Bassa be provided, its quick-acting and lasting effect good, cost is lower, good to pest controling effect, particularly has good control efficiency to rice fulgorid and thrips.
The present invention adopts following technical scheme to achieve these goals:
