Abstract
The invention relates to insecticidal composition containing pyridalyl and efficient cyhalothrin and application thereof. Based on active ingredients, the weight ratio of the pyridalyl to the efficient cyhalothrin in the composition is 1:100-100:1, preferably 1:10-20:1. The invention further relates to a preparation method of the insecticidal composition, and application of the insecticidal composition to controlling agricultural lepidopteran pests.
Description
Technical field
The present invention relates to a kind of synergetic pesticide composition, is a kind of effect that comprises the Synergistic insecticidal compositions of pyridalyl and gamma cyhalothrin and this Synergistic insecticidal compositions is used to prevent and treat the lepidoptera pest on the agricultural.
Background technology
Lepidoptera pest kind on China's agricultural is many, and feeding habits are assorted, and host range is wide, and life cycle is short, and fertility is extremely strong, all can take place the following whole year at greenhouse experiment, and generation overlap is serious.Increase in case number of pest is explosion type, will cause significant damage, cause plant growth to be stagnated crop, plant early ageing, the fruit deformity seriously reduces product and quality.
In agriculture lepidoptera pest control,, insecticide is prone to develop immunity to drugs at present because insect is many from generation to generation, breeding is fast, the good insecticide of some original control efficiency, through use for many years, insecticidal effect obviously reduces, and the lasting period is short.Even simply increase spraying times and usage amount do not reach desirable control efficiency yet, also increased toxic pollutant to human and environment.Along with the raising of agricultural products in China production technology level and importer to the technology barriers of the export of farm produce, in the control of insect, more need high-quality and efficient agricultural chemicals and scientific and reasonable use, to reduce residue of pesticide, improve the quality of agricultural product.
Pyridalyl has another name called fluoroform pyrrole ether, english common name: pyridalyl, chemical name: 2-{3-[2.3-two chloro-4-(3,3-two chloro-2-acrylic oxygen bases) phenoxy group] propoxyl group }-5-(trifluoromethyl) pyrimidine, molecular formula: C

-6(pH value 5.0), in acetone, methyl alcohol, toluene, n-hexane, ethyl acetate＞500, stability: stable to light, stable more than 6 months under 15 ℃～25 ℃ conditions, stable under acid condition, hydrolysis in alkaline medium.Gamma cyhalothrin is a pyrethroid insecticides, through suppressing the conduction at insect neural axon position, insect is had the effect of walking quickly and keeping away, knocking down and killing; Insecticidal spectrum is wide, and active higher, drug effect is rapid; Spray the back resistance of rainwater washing against, the insect of sucking mouth parts is had good preventive effect.
For the insect that be prone to produce resistance on the agricultural, effective method is the new varieties that exploitation and existing agricultural chemicals do not have cross resistance.But in present stage, research and develop out a kind of efficient, low toxicity, not only cost is high, the time is long but also difficulty is very big for oligosaprobic novel pesticide.Therefore, from present actual conditions, comparatively efficient ways be the heterogeneity with synergistic effect is carried out rationally composite, to reach the purpose of pest being carried out integrated control.
Pyridalyl and gamma cyhalothrin are the diverse insecticides of the mechanism of action, and the stack that the two composite effect that shows or activity level exceed each composition activity has unforeseeable synergistic function.Being mixed of pyridalyl and gamma cyhalothrin not only can enlarge insecticidal spectrum, has complementary advantages, and also can slow down drug-fast generation simultaneously, prolongs the service life of product.The Pesticidal products that pyridalyl and gamma cyhalothrin are arranged is in the market used extensivelyr, but does not see both complex preparation product so far as yet.
Summary of the invention
One of the object of the invention is to provide a kind of Pesticidal combination that contains pyridalyl and gamma cyhalothrin, and it has excellent synergy control efficiency.
Another object of the present invention provides said preparation of compositions method and is used to prevent and treat the purposes that agricultural goes up lepidoptera pest.
Synergetic pesticide composition of the present invention contains the aforesaid active principles in combination of synergy effective dose, and the ratio between the active component can change within a large range.Wherein, pyridalyl and gamma cyhalothrin are 1:100～100:1, more preferably 1:10～20:1 based on the weight ratio of active component.
