Description
Technical field
The present invention relates to a kind of insect repellent, be specially a kind of Insect Pests in Rice snout moth's larva of rice adult repellant and preparation method thereof.
Background technology
The snout moth's larva of rice, comprises striped rice borer
chilo suppressalisand pink rice borer
sesamia inferens, be the important pests of China paddy rice.Striped rice borer belongs to Lepidoptera Pyralidae Pyralidae, and pink rice borer belongs to Lepidoptera Noctuidae Noctuidae, extensively distributes in temperate zone, Asia, subtropics, and host plant comprises paddy rice, corn, sugarcane, grain, broad bean, wild rice stem, Chinese sorghum, wheat etc.In recent years, along with change, the climate warming of China's cropping system and rice varieties, the living environment of striped rice borer is greatly improved, and population quantity significantly rises.The snout moth's larva of rice based on striped rice borer become continue the eighties rice fulgorid, the Severe pests of another serious threat national economy after nineties cotton bollworm.
The snout moth's larva of rice is with larva moth food Culm of Rice, and paddy rice is injured in tillering stage and causes withered heart seedling and withered sheath; To be injured at booting stage, heading stage withered booting and dead ears; Pustulation period, milk ripe stage, are injured, and cause half withered fringe and insect bite strain, blighted grain increases, and meet the folding that blows hard easily to fall, cause paddy quality and production declining.
For a long time, chemical control is the topmost means of prevention of the snout moth's larva of rice always, the medication frequency is high, dosage is large, irrational medication has killed and wounded natural enemy in large quantities, heavy damage agricultural ecological balance, makes insect lose natural contral, forms vicious circle, final initiation pest resistance to insecticide, also results in serious Pesticide Residue.Especially striped rice borer is prevented and treated, maximum in rice earing stage medication, very easily cause paddy residue of pesticide to exceed standard (malicious paddy and malicious rice), cause serious environmental pollution and food-safety problem.
Therefore need a kind of high effect nontoxic Sustainable Treatment technology badly, and utilize repellant drive snout moth's larva do not lay eggs in rice strain (or reduce in rice strain output) be the new method of a kind of more satisfactory and simple and effective water prevention rice borer.Also do not find at present specially for the efficient oviposition detterent agent of the snout moth's larva of rice.
Summary of the invention
The object of the invention is to the deficiency existed for existing water prevention rice borer technology and product, provide a kind of snout moth's larva of rice repellant compositions, snout moth's larva of rice adult moves out of rice field because of olfactory nerves irriate, paddy rice does not lay eggs.
A further object of the present invention is to provide the microemulsion, granule and preparation method thereof that adopt described snout moth's larva of rice repellant compositions obtained.
The present invention further object is to provide the application method of described snout moth's larva of rice repellant.
The technical solution adopted for the present invention to solve the technical problems is:
On the one hand, the invention provides the combination of the compound of a kind of repellent snout moth's larva of rice adult, composition comprises: cedrol, ocimene, australene and methyl cinnamate.
Preferably, a kind of snout moth's larva of rice oviposition detterent provided by the invention agent, comprises the following component in total weight percent: cedrol 3-50%, ocimene 0.1-30%, australene 0.01-30%, methyl cinnamate 0.5-20%;
Further, described snout moth's larva of rice repellant comprises the component of following weight proportioning: cedrol 10-40%, ocimene 0.5-20%, australene 0.1-15%, methyl cinnamate 0.5-10%.
Further, described snout moth's larva of rice repellant comprises the component of following weight proportioning: cedrol 10-30%, ocimene 0.5-10%, australene 0.3-10%, methyl cinnamate 2.0-8%.
On the other hand, snout moth's larva of rice repellant, can be made into various formulation of the prior art, such as aqueous emulsion, microemulsion, missible oil, granule or paste etc.
Through lot of experiment validation, when dosage form selection be microemulsion and granule time, its repellent effect reaches best.
When making microemulsion, in total weight percent, auxiliary agent is made up of following component: antioxidant is selected from 2,6-BHT, ascorbic acid receive in one or both 0.03-0.5%, neopelex 2-3%, glycerine 3-5%, Sodium Benzoate 0.3-0.5%, guar gum 0.2-0.5%, emulsifier 10-12%.
On the other hand, the invention provides the preparation method of snout moth's larva of rice repellent microemulsion, step is as follows:
(1), provide compound combination, composition comprises: cedrol, ocimene, australene and methyl cinnamate;
(2), by active ingredient mix and blend, heating for dissolving, obtained oil phase;
(3), by water, auxiliary agent mixing and stirring;
(4), slowly add in (3) by (2), stir emulsification pretreatment, sampling, inspection, to obtain final product.
When making granule, in total weight percent, auxiliary agent is become to be grouped into by following: antioxidant is selected from 2,6-BHT, ascorbic acid receive in one or both 0.03-0.5%, aminotransferase 0.03-0.09%, activated carbon 20-40%, polyvinyl alcohol 0.3-0.5%, Sodium Benzoate 0.3-0.5%, guar gum 0.2-0.5%.
The preparation method of snout moth's larva of rice repellent granule, also comprises the steps:
By each component mixing except activated carbon, be dissolved completely in n-hexane, then activated carbon be placed in mixed solution and soak 48 ~ 72h, pull out, drain.
Above-mentioned snout moth's larva of rice repellant is applied to repellent snout moth's larva of rice pink rice borer, rice stem borer is laid eggs.
