Embodiment 1

[0033] Benthiazamide: 40%, Bicyclic Sulcotrione: 5%, Lignosulfonate: 4%, Alkamide Polyoxyethylene Ether: 10%, Hollow Glass Microspheres: 25%, Silica: 10% %, potassium chloride make up to 100%.

[0034] The preparation method is as follows: (1) uniformly mix mefenamide, bicyclic sulcotrione, surfactant and filler according to the proportion, and then ultrafinely pulverize by jet mill to obtain mother powder;

[0035] (2) Use an adsorbent to evenly absorb the oily water surface spreading agent to obtain a powder;

[0036] (3) Pour the mother powder of step (1), the powder of step (2) and the solid core material into a double-helix conical mixer and mix for 10-30 minutes; then add an appropriate amount of water to extrude and granulate, and finally Dried to obtain large granules of herbicide.

Embodiment 2

[0037] Example 2: Thienacet: 35%, Bicyclic Sulfotrione: 10%, Sodium Naphthalene Sulfonate Formaldehyde Condensate: 6%, Alkyl Fatty Acid Ester: 12%, Pumice: 30%, White Carbon Black: 8%, ammonium sulfate supplemented to 100%.

[0038] The preparation method is the same as in Example 1.

Embodiment 3

[0039] Example 3: mefenamide: 30%, bicyclic sulcotrione: 15%, polycarboxylate anions: 5%, vegetable oil: 10%, pseudo-calcined pumice: 40%, white carbon black: 10%, Sodium sulfate topped up to 100%.

[0040] The preparation method is the same as in Example 1.

Abstract

The invention provides a weeding macrogranule for a paddy field. The weeding macrogranule is prepared from the following components in percentage by weight: 1% to 50% of mefenacet, 1% to 25% of benzobicyclon, 0.5% to 25% of surfactant, 1% to 30% of oily water surface spreader, 10% to 50% of solid core material, 1% to 20% of adsorbent, and 10% to 50% of filler. The weeding macrogranule for the paddy field has the advantages that because the floating material is used, the weeding microgranule can float onto the water surface, and automatically disperse under the actions of wind and self additive; by introducing a high-performance dispersant into the formula, the effective components of the weeding macrogranule can be diffused into the whole field within short time after applying; the effectof the weeding macrogranule is lasting, the labor intensity is decreased, and the time is shortened.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a large herbicide for paddy fields and a preparation method thereof. Background technique [0002] Rice is an important grain and economic crop in my country, and its planting area is very wide, and it occupies a pivotal position in the daily life of the people. The commodity rate of rice is affected by many factors such as planting conditions and management measures. The main solutions at present are to cultivate fine varieties, popularize chemical weeding techniques and improve mechanized harvesting. [0003] At present, pre-emergence sealing herbicides in paddy fields mainly use amides as a single agent or as a compound preparation with oxadiazon. The safety of chloramine to different rice varieties and different application periods is also different. In addition, these pesticides have been used for a long time, and the amount of application has increased year by year, which has ca...
