Abstract
The invention relates to a method for preparing the cartap-imidacloprid composite wettable powder of a crop pesticide. The wettable powder mainly comprises cartap and imidacloprid. The method comprises the following steps that: firstly, an amount of a composite auxiliary agent is added in an amount of 95 percent imidacloprid raw pesticide so as to prepare 10 percent wettable powder; the composite auxiliary agent is mixed by light calcium carbonate, white carbon black and sodium alkyl naphthalene sulfonate according to a certain mixture ratio of 10:2.5:1; and the mixture is mixed with an amount of 95 percent cartap through air flow. Moreover, the mixture ratio of 95 percent imidacloprid to 95 percent composite cartap auxiliary agent is 1:12-18:19-12.
Description
Technical field
The present invention relates to a kind of preparation method of crops pesticide, particularly a kind of method for preparing cartap and imidacloprid combined water dispersible powder.
Background technology
Snout moth's larva and plant hopper are insect pest of rice.At the paddy rice middle and advanced stage is simultaneous two big primary pests, in order to reach a drug root smelting insect, reaches and protects the purpose of producing Bao Feng.
Cartap (chemical name: 1,3-two (carbamyl sulphur)-2-dimethylaminopropanecompounds, English common name: cartap) nereistoxin insecticide, tool are tagged, stomach poison function, certain interior suction conduction is arranged and ovum performance is extremely arranged.This product has good control efficiency to Lepidoptera, coleoptera.
Imidacloprid (chemical name: 1-(6-chloro-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine, English common name: imidacloprid), chlorination nicotinoyl insecticide, have interior suction, stomach toxicity, food refusal effect equally, be mainly used to prevent and treat sucking pest, and Lepidoptera, coleoptera are also had good control efficiency.
The synergistic complex of agricultural chemicals is the expanding prevention spectrum and improves the effective measures of preventive effect and improve peasant's production efficiency, up to now, still finds no the report that closes cartap and imidacloprid combined water dispersible powder.
Purpose of the present invention just provides a kind of cartap and imidacloprid Recompounded pesticide, and the expanding prevention spectrum improves drug effect and production efficiency, reduces agricultural chemicals usage amount and joint medicine time, reduces cost, and reduces environmental pollution.
Summary of the invention
Cartap and imidacloprid combined water dispersible powder agent preparation method, mainly be with water miscible cartap and two kinds of insecticides of oil-soluble Imidacloprid through being processed into the combined water dispersible powder agent, contain cartap 36-48%, Imidacloprid 3-5% in its combined water dispersible powder agent.
The technology of the present invention solution:
A kind of preparation method of cartap and imidacloprid combined water dispersible powder agent is characterized in that earlier the former medicine of a certain amount of 95% Imidacloprid being added a certain amount of " composite assistants ", is made into the wetting powder about 10%." composite assistants " is to be mixed by a certain percentage by precipitated calcium carbonate, white carbon black and Negel, and its ratio is 10: 2.5: 1, mixes through air-flow with a certain amount of 95% cartap then.95% Imidacloprid, 95% cartap and composite assistants proportioning are 1: 12-18: 19-12.
Advantage of the present invention and beneficial effect
(1), cartap is close with the Imidacloprid mechanism of action, desinsection has complementarity, compound synergic is remarkable, but by the composite desinsection wet-milling that forms of the present invention, has higher compound synergic effect, the preparation stable performance;
(2), snout moth's larva and plant hopper be simultaneous at the paddy rice middle and advanced stage basically, by the composite insect that reaches a drug radical cure paddy rice middle and advanced stage of these two kinds of agricultural chemicals.
Embodiment
Example one
With 32Kg content is that the mixing and blending machine that passes through of 95% Imidacloprid adds 570Kg " composite assistants ", mix, after add the 398Kg95% cartap and mix again, then the Imidacloprid of thick mixing and cartap are made required target product after the full and uniform mixing of air-flow mixing cracker.
Embodiment two
With 40Kg content is that the mixing and blending machine that passes through of 95% Imidacloprid adds 330Kg " composite assistants ", mix, after add the 630Kg95% cartap and mix again, then the Imidacloprid of thick mixing and cartap are made required target product after the full and uniform mixing of air-flow mixing cracker.
Implement three
With 32Kg content is that the mixing and blending machine that passes through of 95% Imidacloprid adds 330Kg " composite assistants ", mix, after add the 640Kg95% cartap and mix again, then the Imidacloprid of thick mixing and cartap are made required target product after the full and uniform mixing of air-flow mixing cracker.
Claims (5)
1, a kind of method for preparing cartap and imidacloprid combined water dispersible powder, it is characterized in that earlier the former medicine of a certain amount of 95% Imidacloprid being added a certain amount of " composite assistants ", be made into the wetting powder about 10%, mix through air-flow with 95% cartap again.
