Abstract
An agricultural chemical for preventing and eliminating the pests of paddy rice is prepared from triazophos, pyridaphenthion, emulsifier, stabilizer and solvent through dissolving triazophos and pyridaphenthion in solvent, mixing, sequentially mixing with others, and filtering. Its advantages are high effect, low dosage and no environmental pollution.
Description
Technical field
The invention discloses a kind of medicament of preventing and treating rice insect pest and preparation method thereof.
Background technology
Paddy rice is the important cereal crops of China, and its sowing area accounts for 1/3 of cereal crops sowing area, and the paddy gross yield accounts for about 45% of total grain output.In China, " northern locust south snout moth's larva " be historic two major pests, and historical a situation arises from China's rice cropping system degree of drilling and snout moth's larva, and the rice cropping system is by changing complexity merely into, and then the paddy stem borer population rises, the decline of striped rice borer population.Otherwise the rice cropping system is become merely by complexity, and then the paddy stem borer population is in and withers and falls, and it is rampant that the striped rice borer population tends to thereupon.Along with the proposition of profitable agriculture, crop mix is further adjusted, the pesticide species structural change, and some regional snout moth's larvas add that to pesticide resistance in various degree such as dimehypo, desinsection list winter temperature is higher, the snout moth's larva amount continues to go up.The medicament of the existing control snout moth's larva of rice mostly is neires toxin and organic phosphor greatly on the market.Desinsection Dan Jing wherein uses for many years and has produced stronger pesticide resistance, and preventive effect is not ideal enough.Exist significant limitation in the use, list can be prevented and treated the snout moth's larva of rice with organic phosphor in addition, but consumption is big, and people and animals, environment are all had harmful effect.
Technical scheme
The objective of the invention is to invent a kind of dosing that reduces, again effective a kind of medicament of preventing and treating rice grub of pest control and preparation method thereof.
The present invention is mainly by Hostathion, pyridaphethione, farm chemical emulgent, stabilizing agent, solvent composition.
Wherein, Hostathion accounts for total amount 20～30%, and pyridaphethione accounts for total amount 4～15%.
Single agent usage amount of the general agricultural chemicals of the present invention reduces greatly, and favourable surrounding environment protection has no adverse effects to people and animals, and can effectively prevent and treat rice grub, and composite medication has tangible synergy.
The present invention prepares by following steps:
A) Hostathion and pyridaphethione are dissolved in solvent respectively;
B) Hostathion solution and pyridaphethione solution are mixed, and add farm chemical emulgent, mix;
C) add stabilizing agent, mix;
D) filter, pack.
The present invention's preparation method has processing step simply, rationally, is easy to control, and is with short production cycle, product percent of pass height, stay-in-grade characteristics.
Be example now, further specify the present invention to produce 1000kg the present invention.
1) takes by weighing 80% Hostathion 250kg respectively, 30% pyridaphethione 334kg, 2201 emulsifier 100kg, stabilizing agent BHT30kg, dimethylbenzene 286kg.
2) Hostathion is dropped in the 150kg dimethylbenzene, stir, make it dissolving.
3) pyridaphethione is dropped in the 136kg dimethylbenzene, stir, make it dissolving.
4) mix Hostathion solution and pyridaphethione solution, after fully stirring, add 2201 emulsifier again, fully stir.
5) add stabilizing agent BHT antioxidant again, fully stir.
6) filter, get filtrate, weighing, packing.
Claims (5)
1, a kind of medicament of preventing and treating rice grub is characterized in that mainly by Hostathion, pyridaphethione, farm chemical emulgent, stabilizing agent, solvent composition.
2, according to the described medicament of claim 1, it is characterized in that Hostathion accounts for total amount 20～30%, pyridaphethione accounts for total amount 4～15%.
3,, it is characterized in that farm chemical emulgent accounts for 6～12% of total amount, stabilizer comprises total amount 3～8% according to the described medicament of claim 2.
4,, it is characterized in that solvent is a dimethylbenzene according to the described medicament of claim 1.
5, a kind of medicaments preparation method of preventing and treating rice grub is characterized in that may further comprise the steps:
A) Hostathion and pyridaphethione are dissolved in solvent respectively;
B) Hostathion solution and pyridaphethione solution are mixed, and add farm chemical emulgent, mix;
C) add stabilizing agent, mix;
D) filter, pack.
