Embodiment 1

[0017] Example 1: 75% quinclorac wettable powder.

[0018] Take by weighing 75% of the former powder of quinclorac, wetting agent sodium lauryl sulfate 2%, dispersant polycarboxylate 2700 3%, sodium lignosulfonate 2%, diffusing agent N2%, filler (white carbon Black: kaolin = 1:2) to 100%, after mixing it evenly, it is pulverized by jet mill to get 75% quinclorac wettable powder. After inspection, the active ingredient content is 75.5%, moisture ≤ 2.0%, pH value 5.7, sieving (through 15μm sieve) ≥ 98%, suspension rate ≥ 98%, persistent foaming (1min) ≤ 10mL, wettability ≤ 45 seconds, the accelerated thermal storage stability is qualified. Through field tests in Guangdong, Hunan, Hubei and other places, the product was compared with spraying and spraying with wettable powder.

[0019] The test processing is as follows:

[0020] .

[0021] The results are shown in the following table: 75% quinclorac wettable powder (throwing application) and ordinary products are comp...

Embodiment 2

[0023] Example 2: 75% tricyclazole wettable powder.

[0024] Weigh 75% of the original powder of tricyclazole, 2% of sodium lauryl sulfate as a wetting agent, 2% of polycarboxylate 2700 as a dispersant, 4% of calcium lignosulfonate, 1% of diffusing agent, and 100% of filler kaolin After mixing it evenly, it was pulverized by a jet mill to obtain 75% tricyclazole wettable powder. After inspection, the active ingredient content is 75.3%, the moisture content is ≤2.0%, the pH value is 6.8, the sieving (through a 15μm sieve) is ≥98%, the suspension rate is ≥95%, the persistent foaming property (1min) is ≤10mL, and the wettability is ≤1min. , Accelerated heat storage stability is qualified. Used to prevent and control rice blast; 15g-20g / 667㎡, (after being packaged in a water-soluble bag, it can be directly thrown into the paddy field, 5g / bag, 3-4 bags / 667㎡), the incidence of rice blast is reduced by 90%~ 100%. It can prevent the occurrence of rice blast very well, saves t...

Embodiment 3

[0025] Example 3: 25% Buprofezin · Isoprocarb wettable powder.

[0026] Weigh 6% of the original powder of buprofezin, 19% of the original powder of isoprocarb, 3% of the wetting agent sodium alkylnaphthalene sulfonate, 3% of the dispersant naphthalenesulfonate formaldehyde condensate NNO, 4% of sodium lignosulfonate, 0.5% of yus-8100, 4% of white carbon black, kaolin remaining, after mixing evenly, pulverized by jet mill to obtain 6% buprofezin 19% isoprocarb wettable powder. The content of active ingredients Buprofezin is 6.2%, the content of Isoprocarb is 19.3%, the moisture content is ≤2.0%, the pH value is 7.5, the sieving (passing through a 15μm sieve) is ≥98%, the suspension rate is ≥95%, and the long-lasting foaming property ( 1min) ≤ 10mL, wettability ≤ 1min, and the accelerated heat storage stability is qualified. The dose of drug used to control rice planthoppers is: 112.5-184.5g (active ingredient) / hm at the initial stage of insect population 2, the control...

Abstract

The invention relates to an environment-friendly type wettable powder capable of being directly applied to a rice field. The environment-friendly type wettable powder comprises the components by weight percent: 0.1-90% of effective components, 1-5% of wetting agent, 1-10% of dispersing agent, 0.1-5% of diffusion agent, the balance of filler and water-soluble packaging film material. The auxiliary agents with different components and the diffusion agent are added into the wettable powder, and the wettable powder is packed in the water-soluble packaging material, so that the wettable powder has the advantages of being high in content of active components, low in environmental pollution, more uniform in spraying, more convenient in application, good in dispersing performance, stable in heat storage performance and the like; when being used, the environment-friendly type wettable powder is high in controlling efficiency and free from dust and liquid medicine drift when being applied, and enables people not to be contacted with the drug, thus being good in safety.

Description

Technical field [0001] The present invention involves an agricultural humidity powder, which specializes in an environmentally friendly wettable powder that can be thrown directly in rice fields. Background technique [0002] Pesticide wettable powder is a dosage form with a long history, mature technology, and convenient use in pesticide processing preparations. Many bactericides, herbicides and some insecticides are often processed into this dosage form. ThereforeTogether with the four basic dosage types called pesticide processing.The wet powder has been developing steadily since the 1950s. In recent years, the number of pesticide preparations registered in my country can also explain this.The number of traditional dosage -type milk and wettable powder is still at the top of the list, occupying an important position in modern pesticide preparations.In recent years, although new dosage types such as pesticide suspension and water -decentralized granules have developed rapidly, ...
