example 1

[0016] Example 1: 32% pretilachlor·clomazone·oxadiazone EC

[0017] Pretilachlor 10%, Clomazone 10%, Clomazone 12%, Cyclohexanone 5%, Calcium Dodecyl Benzene Sulfonate 4%, Styrene Phenol Polyoxyethylene Ether 2%, Castor Oil Polyoxygen Vinyl ether 3%, mineral spirits make up to 100%.

[0018] Put cyclohexanone and solvent oil into the kettle, stir and dissolve oxadiazone completely, then put the remaining ingredients into the kettle, stir until completely dissolved, and then 32% acetochlor·clomazone·oxadiazone EC can be prepared .

example 2

[0019] Example 2: 19% pretilachlor·clomazone·propargyl clomazone EC

[0020] Pretilachlor 5%, clomazone 12%, propargyl clomazone 2%, cyclohexanone 5%, calcium dodecylbenzenesulfonate 3%, styrene phenol polyoxyethylene ether 3%, castor oil Polyoxyethylene ether 2%, mineral spirits make up to 100%.

[0021] Put cyclohexanone and solvent oil into the kettle, stir and dissolve propargyl clomazone completely, then put the remaining ingredients into the kettle, stir until completely dissolved, and then 19% propachlor clomazone propyne can be prepared Oxadiazone EC.

example 3

[0022] Example 3: 28% pretilachlor · clomazone · clomazone wettable powder

[0023] Pretilachlor 5%, clomazone 13%, clomazone 10%, sodium lauryl sulfate 2%, sodium methylene bis-naphthalene sulfonate 4%, calcium lignosulfonate 3%, white carbon black 6%, kaolin fills up to 100%.

[0024] Add the above materials together into a conical mixer and mix them evenly, crush them with a jet mill and mix them until the material fineness reaches 98% and pass through a 325-mesh sieve to obtain 28% pretilachlor clomazone oxazone Ketone wettable powder.

Abstract

The invention belongs to the field of agricultural chemicals and in particular relates to a paddy field synergistic weeding composition. The paddy field synergistic weeding composition is characterized by comprising the following active ingredients in percentage by weight: 5-40 percent of oxadiazon or 0.5-20 percent of oxadiargyl, 5-30 percent of pretilachlor or butachlor and 2-30 percent of clomazone. According to the composition, the weeding effect can be improved, the herbicide controlling spectrum is widened, the composition is low in toxicity and small in residual, and the pesticide hazard on rice is reduced. Moreover, the dosage, the administration frequency and the use cost are obviously reduced, the effect of the composition is obviously higher than that of each single-dose agent, and the paddy field synergistic weeding composition is suitable for controlling and eliminating of annual and perennial weeds in paddy fields.

Description

(1) Technical field [0001] The invention belongs to the field of agricultural chemicals, in particular to a paddy field synergistic herbicide composition. (2) Background technology [0002] Pretilachlor, English common name: pretilachlor, chemical name: 2-chloro-N-(1-methyl-2-methoxyethyl)-N-(2-ethyl-6-methylphenyl)acetamide . This product is a pre-emergence herbicide, mainly used to control grass weeds. The product is a 2-chloride acetylaniline herbicide, which is a cell division inhibitor. It can be used in soil treatment to control barnyardgrass, heteromorphous sedge, cattle felt, Yujiuhua, and Alisma narrow leaves. It is usually used 3-5 days before transplanting. This product has poor selectivity to wet-inserted rice when it is applied alone, but it has excellent selectivity to direct-inserted rice when it is used together with Jiecaidin. Annual gramineous and broad-leaved weeds such as cow felt, Alisma narrow-leaf, water amaranth, special-shaped sedge, broken r...
