Embodiment 1

[0032] Embodiment 1: The composition of 9% benzsulfuron-methyl floating type herbicide (mass percentage %) is as follows: bensulfuron-methyl 0.8, acetochlor 8, metsulfuron-methyl 0.2, active carbon clay 20, alkylsulfonate 3.0; Machine oil 8.5 ; Expanded pearl powder 59.5.

[0033] Mix the above-mentioned amount of bensulfuron-methyl, acetochlor, metsulfuron-methyl, activated clay, alkyl sulfate, and lignosulfonate with a grinder and pulverize them to make powder; then put the expanded pearl powder on the tray On the type coating machine, add the above-mentioned amount of engine oil dropwise, after the engine oil is fully dispersed, at room temperature, gradually add the above-mentioned powder to the pre-treated light carrier in the pan-type coater, and then mix well, Subpackage is finished product.

[0034] When in use, the above-mentioned floating agent is sprinkled on the water surface of the paddy field within 3-7 days after the rice seedlings are thrown or transplanted. T...

Embodiment 2

[0035] Embodiment 2: B, benzyl floating type herbicide (mass percent %) is composed as follows: bensulfuron-methyl 5, acetochlor 7, promethazine 15.8, pyrocatechol 0.7, activated zeolite powder 25, sodium lignosulfonate 4.5, oleic acid 19.0, expanded vermiculite 33.0.

[0036] Its manufacturing process is the same as embodiment (1).

Embodiment 3

[0037] Example 3: The composition of 8% dimehypo floating agent (mass percentage %) is as follows: 8.0 dimehypo, 30 activated carbon, 3.0 polyoxyethylene alkyl ether, 14.0 fatty acid, and 45.0 expanded perlite.

[0038] Its manufacturing process is the same as embodiment (1), and when subpackaging, above-mentioned preparation is subpackaged in 50 grams of water-soluble bags.

Abstract

The invention discloses the composite of an environment-friendly rice flotable agricultural chemical preparation and a novel manufacture process thereof, which belongs to the field of farm chemical. The preparation is formed by compounding 0.1 to 50 percent of a weed killer, an insecticide, a fungicide or plant growth regulator active ingredients, 0.1 to 30 percent of a micropore sustained release agent, and 99.8 to 20 percent of a floatble carrier according to mass percentage. The preparation can effectively save the active ingredients by more than 70 percent, and can be directly applied on the surface of rice paddy field. The preparation has the characteristics of low cost, high efficacy, lasting drug action, safety, convenient use and so on, and is an environment-friendly agricultural chemical preparation.

Description

technical field [0001] The invention belongs to the field of pesticide manufacture. The invention relates to a paddy field herbicide, an insecticide and a fungicide, a plant growth regulator and a preparation method. Background technique [0002] At present, the dosage forms of rice field agrochemical preparations mainly include: wettable powder, granule, microgranule, soluble powder, suspension concentrate, emulsion, effervescent agent, etc. These preparations have high main ingredient content and low utilization rate of active ingredients. The preparation process requires ultrafine pulverization, granulation, or emulsification with a large amount of solvents. The process is complex, high energy consumption, high cost, and large pollution. [0003] For this reason, the inventor invented a kind of agrochemical preparation in the patent No. 98112697.9 patent, promptly utilizes the composite active ingredient of lightweight particle material to make chemical floating agent. ...
