Abstract
The invention discloses a pesticide, in particular to a pesticide for preventing and treating rice pests and a preparation method thereof. The pesticide for preventing and controlling rice pests mainly comprises trichlorfon, quinalphos, a pesticide emulsifier, a stabilizer and a solvent, and the preparation method comprises the following steps: dissolving trichlorfon in a solvent respectively; mixing the emulsifier with the trichlorfon and quinalphos solution; adding a stabilizer into the mixed solution obtained in the step a and the step b, and stirring; and (6) filtering and packaging. Compared with single dosage, the invention has the advantages of greatly reduced dosage, obvious synergy, reduced pollution to the environment, and effective prevention and control of rice pests, especially chilo suppressalis and tryporyza incertulas.
Description
Technical field
The invention discloses a kind of agricultural chemicals, especially for agricultural chemicals of preventing and treating rice grub 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 rice cropping system mountain complexity becomes merely, 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 object of the invention is to invent a kind ofly can effectively prevent and treat agricultural chemicals of rice grub and preparation method thereof, reduces spraying medicine concentration, to reduce environmental pollution.
The present invention is mainly by chlorophos, quinalphos, farm chemical emulgent, stabilizing agent, solvent composition.
The present invention uses single agent to reduce greatly more separately, and has tangible synergy, can reduce pollution on the environment, can effectively prevent and treat rice grub, particularly striped rice borer, paddy stem borer.
Among the present invention,, guarantee control efficiency simultaneously, choose chlorophos content and account for total amount 15～35% that total amount 5～15% on the quinalphos content for reducing cost.
Stable for improving the quality of products, the present invention also adds 3～6% stabilizing agent.
Preparation method of the present invention comprises the steps:
A) the chlorophos quinalphos is dissolved in solvent respectively;
B) emulsifier is mixed with chlorophos, quinalphos solution;
C) stabilizing agent is added in the mixed liquor of step a and b, stir;
D) filter, pack.
Simultaneously, the solvent of dissolving chlorophos is DMF and dimethylbenzene, and the solvent of dissolving quinalphos is a dimethylbenzene.
Production technology of the present invention is reasonable, and is with short production cycle, is easy to control, the product percent of pass height, and quality stability is good.
For giving full play to drug effect, in the preparation, after earlier chlorophos and quinalphos fully being dissolved with DMF, dimethylbenzene and dimethylbenzene respectively, again solution is mixed.
Specific embodiment:
With preparation 1000kg the present invention is example:
1) takes by weighing 90% chlorophos 312kg respectively, 90% quinalphos 78kg, 3208 emulsifier 100kg, BHT antioxidant 30kg, DMF100kg, dimethylbenzene 380kg.
2) chlorophos is dropped in DMF and the 200kg dimethylbenzene, fully stir, chlorophos is dissolved fully.
3) quinalphos is dropped in the 100kg dimethylbenzene, fully stir, quinalphos is dissolved fully.
4) mix chlorophos solution and quinalphos solution, and add residue dimethylbenzene, fully stir.
5) in above-mentioned mixed liquor, add emulsifier, and stir.
6) add the BHT antioxidant again, and fully stir.
7) above-mentioned mixed liquor is filtered, get filtrate.
8) weighing, packing.
Above-mentioned 3208 emulsifier can 0204 or 2201 or 0201 replacement.
Claims (7)
1, the agricultural chemicals of control rice grub is characterized in that mainly by chlorophos, quinalphos, farm chemical emulgent, stabilizing agent, solvent composition.
2, according to the described agricultural chemicals of claim 1, it is characterized in that chlorophos content is 15～35%, quinalphos content is 5～15%.
3,, it is characterized in that stabiliser content is 3～6% according to the described agricultural chemicals of claim 2.
4,, it is characterized in that solvent is DMF and dimethylbenzene according to the described agricultural chemicals of claim 1.
5, the agricultural chemicals preparation method of control rice grub is characterized in that may further comprise the steps:
A) the chlorophos quinalphos is dissolved in solvent respectively;
B) emulsifier is mixed with chlorophos, quinalphos solution;
C) stabilizing agent is added in the mixed liquor of step a and b, stir;
D) filter, pack.
6, according to the described method of claim 5, the solvent that it is characterized in that dissolving chlorophos is DMF and dimethylbenzene.
7, according to the described method of claim 5, the solvent that it is characterized in that dissolving quinalphos is a dimethylbenzene.
