Problems solved by technology

[0004] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Uniformity is also likely to cause residual toxicity to current crops or subsequent crops

Abstract

The invention provides water dispersible granules containing penoxsulam and oxaziclomefone. The water dispersible granules are prepared from, by weight, 10-50% of penoxsulam, 5-10% of oxaziclomefone, 2-10% of a wetting agent, 2-8% of a dispersing agent, 3-6% of glycine betaine, 0.5-6% of an adhesive and the balance filler. The adhesive is a mixture of coal ash and fumed silica. According to the water dispersible granules, the weeding spectrum is enlarged, broad-leaved weed and grassy weed of rice can be effectively removed, the water dispersible granules are safe to current and succeeding crops, and meanwhile the granule consumption cost of a farmer is lowered.

Description

technical field [0001] The invention belongs to the technical field of herbicides, and in particular relates to a water-dispersible granule containing penoxsulam and oxaziclozone. Background technique [0002] Penoxsulam, English common name penoxsulam, sulfonylurea herbicide, is a conductive herbicide, absorbed by stems, leaves, buds and roots, and transmitted to meristems through xylem and phloem, inhibiting plant growth and making growth points Chlorosis, 7-14 days after treatment, the terminal buds turn red and necrotic, and the plants die in 2-4 weeks; this agent is a strong acetolactate synthase inhibitor, and the agent appears slowly, and it takes a certain period of time for the weeds to gradually die. It can be used to control barnyardgrass and annual sedge weeds in paddy fields, and is effective against a variety of broad-leaved weeds. [0003] Oxazimidone, also known as debainan, chemical name: 3-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-6-methyl- 5-Phe...
