Description
Technical field
The present invention relates to a kind of Pesticidal combination and preparation method who contains insecticidal active ingredient Nitenpyram and fipronil bisamide.
Background technology
Rice leaf roller and rice fulgorid are two kinds of migrating property pest, are two kinds of insects before several kinds of important damage by disease and insect rows of causing harm serious on rice in China is produced, and the two time of origin is close.The agricultural chemicals of in the past preventing and treating these two kinds of insects is to be main complex preparation with the chlopyrifos, generally selects for use chlopyrifos and emamectin-benzoate, fluorine worm nitrile, Buprofezin or Imidacloprid to carry out composite.In recent years, because the frequent use of Avermectins medicament, pest resistance is relatively more serious.Fluorine worm nitrile has excessive risk to shell-fish aquatile and honeybee in addition, and degraded is forbidden strictness from October 1st, 2009 slowly in water and soil earth.
Fipronil bisamide; Belong to novel phthalic amide insecticides, through activating calcium release channel in blue Buddhist nun's alkali recipient cell, the uncontrolled that causes storing calcium ion discharges; It is the compound that acts on the blue Buddhist nun's alkali of insect cell acceptor at present few in number; Lepidoptera pest there is the wide spectrum preventive effect, does not have cross resistance with existing insecticide and produce, be suitable for very much the control of insect that existing insecticide produces resistance.Larva there is very outstanding preventive effect, limited to the adult preventive effect, there is not ovicidal action.Resistance of rainwater washing against is slightly conducted in the back in the infiltration plant body through xylem.
Nitenpyram is a kind of nicotimine insecticides of exploitation after Imidacloprid; Have super-high-efficient, wide spectrum, consumption is few, toxicity is low, lasting medicine, crop is not had poisoning, advantage such as safe in utilization, is the new varieties of the malicious organophosphorous pesticide of a kind of alternative height of domestic new popularization in recent years.Along with the reinforcement that its price further reduces and applies, the Nitenpyram bright development prospect is worth expectation.There are 6 families in the main manufacturing enterprise of present domestic Nitenpyram, 2009 the end of the year domestic production capacity be about 1000 tons/year, wherein much be new device, output is about about 500 tons, far can not satisfy domestic demand, is worth the attention of domestic pesticide producing and the unit of applying.
Different active ingredients are carried out composite, be the double insect pest of curing the disease, improve drug effect, reduce the medication number of times, reduce the control cost and delaying drug resistance produces method commonly used.To the practical problem of using fipronil bisamide at present separately or Nitenpyram pest control dosage is big, cost is high, repeated use is prone to make insect generation resistance, the synergistic composition that a kind of mixed ratio is reasonable, control efficiency good, drug cost is low need be provided.Through inventor research, find Nitenpyram and fipronil bisamide can produce good synergistic effect after composite.Relevant report about Nitenpyram and fipronil bisamide are composite is still unexposed.
