Embodiment 1

[0029] Bicyclic sulcotrione 0.5%, pretilachlor 0.5%, penoxsulam 0.1%, sodium a-alkenyl sulfonate (AOS) 1%, sodium lignosulfonate (REAX82P) 4%, glucose 6%, white Carbon black 5%, kaolin the balance. Weigh the pretilachlor crude oil in advance according to the above ratio, absorb it with white carbon black and let it stand for 24 hours, mix the above other ingredients according to the above ratio evenly, and pass through airflow pulverization, so that the average particle size of the material is less than 5 microns, and knead evenly with water, Move to granulation equipment for granulation, and dry at 45°C to obtain 1.1% bicyclic sulcotrione·pretilachlor·pentoxsulam granules (5:5:1).

Embodiment 2

[0031] Bicyclic sulcotrione 1%, pretilachlor 1%, penoxsulam 0.1%, sodium lauryl sulfate 1%, naphthalenesulfonate dispersant (MORWET D425) 5%, polyethylene glycol 4000 5% , white carbon black 10%, attapulgite balance. Weigh pretilachlor in advance according to the above ratio, absorb it with white carbon black and let it stand for 24 hours, then mix the other ingredients uniformly according to the ratio, and crush them by air flow, so that the average particle size of the material is less than 5 microns, add water and knead evenly, and move to Granulate in granulation equipment and dry at 45°C to obtain 2.1% bicyclosulam·pretilachlor·pentoxsulam granules (10:10:1).

Embodiment 3

[0033] Bicyclic sulcotrione 10%, pretilachlor 20%, penoxsulam 2%, calcium dodecylbenzene sulfonate 8%, sodium lignosulfonate 7%, fatty alcohol polyoxyethylene ether 3%, white Carbon black 8%, kaolin the balance. After absorbing pretilachlor crude oil and white carbon black according to a certain ratio and letting it stand for 24 hours, mix all the ingredients evenly according to the above ratio, and jet mill to make the average particle size of the material less than 5um. A 32% bicyclic sulcotrione·pretilachlor·pentoxsulam wettable powder (5:10:1) can be obtained.

Abstract

The invention discloses a herbicidal composition containing benzobicyclon, pretilachlor and penoxsulam, relating to the technical field of pesticide compounding. The herbicidal composition is prepared from the following effective components: the benzobicyclon, the pretilachlor and the penoxsulam, wherein the weight ratio of the benzobicyclon to the pretilachlor to the penoxsulam in the herbicidal composition is (1 to 30) to (1 to 30) to 1; the total weight percentage of the benzobicyclon, the pretilachlor and the penoxsulam in the composition is 1 to 80 percent. According to the herbicidal composition disclosed by the invention, a herbicide controlling spectrum can be significantly widened and the overall control effect on weeds in a paddy field is improved; meanwhile, the composition has good safety for rice, and is an excellent novel medicinal combination for controlling annual weeds in the paddy field.

Description

technical field [0001] The invention belongs to the field of agricultural chemistry, and in particular relates to a herbicidal composition containing bicyclic sulcotrione, pretilachlor and penoxsulam aimed at solving the problem of controlling annual weeds in paddy fields. Background technique [0002] Bicyclic sulcotrione (benzobicylon) belongs to bicyclooctane herbicides, and its mechanism of action is a p-hydroxyphenylpyruvate dioxygenase inhibitor. The compound is safe to rice, and can effectively control barnyard grass, bermudagrass, moshangcai, sagittarius, yujiuhua, flat stalk and other malignant weeds in rice fields. [0003] Pretilachlor belongs to the chloroacetamide herbicides, which mainly inhibit the growth of cells by hindering protein synthesis. The drug can be absorbed through the plant hypocotyl, mesocotyl and coleoptile, and slightly absorbed by the root. The symptoms of damage are that the primary leaves do not emerge or protrude from the side of the cole...
