Abstract
The invention relates to the application of 2-(E)-substituted benzylidene-6-dimethylamino methyl cyclohexanone hydrochloride in a pesticide composition for preventing rice-stem borers. The pesticide composition for preventing rice-stem borers containing cyclohexanone has a good preventing effect and is suitable for large-scale popularization in the field.
Description
Technical field
The present invention relates to pesticide field, specifically, the present invention relates to a kind of new opplication of composition pesticide of the water prevention chilo suppressalis containing cyclohexanone.
Background technology
Striped rice borer belongs to Lepidoptera, Ming E section, is one of primary pest of Rice Production, and English name is rice stem borer or striped stem borer.Striped rice borer is one of serious threat Rice Production primary pest, and in temperate zone, Asia, subtropics, south of europe various countries, the U.S. and the Africa countries and regions such as Egyptian, Australian endanger heavier.
Striped rice borer bores moth Culm of Rice for feature with larva, is that a kind of property for many years of surviving the winter with larva often sends out insect.Paddy rice all can be injured in different breeding times, the shape difference of being injured of formation.The diversity phase is injured and causes " the withered heart ".Striped rice borer is very wide in China's distribution, and generating capacity is large, and serious harm all can be caused to paddy rice in the southern north.
Summary of the invention
The object of the present invention is to provide a kind of new opplication of composition pesticide of the water prevention chilo suppressalis containing cyclohexanone.
In order to realize object of the present invention, the invention provides 2-(the E)-purposes of substituted-phenyl methylene-6-dimethylamine methyl cyclohexane keto hydrochloride in the composition pesticide preparing water prevention chilo suppressalis.
Preferably, described composition pesticide can be spray, emulsion or pulvis.
The composition pesticide of the water prevention chilo suppressalis containing cyclohexanone of the present invention has good control efficiency, is suitable in field large-scale promotion.
Embodiment
Below by way of the description of embodiment, the invention will be further described, but this is not limitation of the present invention, those skilled in the art are according to basic thought of the present invention, various amendment or improvement can be made, but only otherwise depart from basic thought of the present invention, all within the scope of the present invention.
Experimental example
At the hybrid rice variety of this paddy field cultivation susceptible insect pest, and lift-augmented mechanism, not use of insecticide, make it to increase the attractive effect to striped rice borer snout moth, in order to collecting enough pieces of an egg.
The striped rice borer pieces of an egg that field gathers first carry out surface sterilization in laboratory, refer again to the white methods of rice seedlings method-water chestnut such as Shang Zhizhen and raise.Feeding environment: warm 26-30 DEG C, periodicity of illumination (illumination: dark) 16h: 8h.Larva after hatching rice seedling-water chestnut from raise about 10d, try worm using the larva of the heavy 6-9mg of polypide as standard during toxicity test.
2-(E)-substituted-phenyl methylene-6-dimethylamine methyl cyclohexane keto hydrochloride precise under sensibility reciprocal 0.1mg balance, adopt organic solvent-acetone to dissolve, and constant volume becomes the mother liquor of 1mgl/mL.
Blade infusion process joins in the distilled water containing 0.1% Tween-80 with mother liquor when measuring respectively, is diluted to the liquid of different pesticide concentration, and with the distilled water adding Tween-80 and a small amount of solvent acetone in contrast.
During topical application method, mother liquor take acetone (containing 20% distilled water) dilution as the liquid of variable concentrations.
Toxicity test method: adopt rice seedling drop method to carry out.
Drop method: test adopts micro intravenous drip device by liquid drop on the mesonotum of every examination worm, often process 30 larvas, 5 dosage established by often kind of medicament, take acetone as contrast, often process and repeat for 3 times, process after examination worm raise in vain with water chestnut, then put into 26 DEG C ± 2 DEG C, relative moisture be 80% culturing room normally cultivate, check result after 48h.
Joint toxicity measuring: adopt the mutual determination method of Horsfall to carry out proportioning screening, with two single dose LC on the basis that single dose measures
50.Concentration preparating liquid, by not carrying out mixed determining on year-on-year basis, virulence ratio is calculated according to actual and expected mortality, select the proportioning that wherein virulence ratio is higher, being scaled different active constituent content respectively carries out composite, then be diluted to variable concentrations to measure with drop method, processing method is the same.
Measurement result is investigated: examination worm process 48h " Invest, Then Investigate " respectively processes dead borer population, calculates lethality, goes out corrected mortality when contrast lethality is greater than 5% by A bbott formulae discovery.
The LC of agricultural chemicals of the present invention
50be 3.43 (mg/L).
Claims (2)
1.2-(the E)-purposes of substituted-phenyl methylene-6-dimethylamine methyl cyclohexane keto hydrochloride in the composition pesticide preparing water prevention chilo suppressalis.
2. purposes according to claim 1, is characterized in that, described composition pesticide can be spray, emulsion or pulvis.
