Embodiment Construction

[0009] 1. Preparation of 10% Cyhalofop-Penoxsulam EC herbicide:

[0010] Weigh 8 kg of cyhalofop-methyl, 2 kg of penoxsulam, 10 kg of Nongru 500 (emulsifier) ​​and 80 kg of xylene (solvent).

[0011] After fully mixing cyhalofop-methyl and penoxsulam in an enamel stirring tank, add emulsifier and solvent, and stir again for 30 minutes to obtain a large package of finished product, which meets or exceeds the national standards for emulsifiable concentrate products. A mandatory indicator requirement.

[0012] 2. The above preparations were tested with 30 milliliters / mu, 45 milliliters / mu, and 60 milliliters / mu of rice barnyardgrass, stephenia, and sedge with a control effect of more than 90%, and the results were better than single products.

[0013] As shown in Table 1, the 10% cyhalofop-pentoxsulam EC control effect on the 20th day density control effect of direct-seeding paddy field daughter, barnyardgrass and sedge:

[0014] (Wuhan, Hubei)

Abstract

The invention provides a missible oil type herbicide containing cyhalofop-butyl and penoxsulam, relates to the technical field of agricultural production, and particularly relates to a production method of a compound pesticide. The missible oil type herbicide containing the cyhalofop-butyl and the penoxsulam provided by the invention can be widely applied to prevention and removal of various weeds of rice direct seeding fields, and particularly has efficient and broad-spectrum weeding performances on various weeds including direct seeding paddy field barnyard grass, leptochloa chinensis, nutgrass flatsedge, convexutricle sedge herb, wild water chestnuts, short sagittaria sagittifolia, alternanthera philoxeroides and paspalum distichum at the periphery of four ridges; and the missible oil type herbicide has no bad influences on crops and the herbicide composite is different from existing other pesticide herbicides.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a production method of compound pesticides. Background technique [0002] Rice is the main food crop in my country, and the country's rice planting area has been stable at about 450 million mu for many years. With the continuous popularization and application of rice light cultivation techniques, the development of direct-directed rice is particularly rapid. Due to its huge advantages of saving labor and cost and liberating rural productivity, it has gradually become a rice cultivation method with broad development prospects in major rice producing areas in my country. Due to the cultivation methods and characteristics of direct-directed rice fields, the occurrence of weed damage in direct-directed rice fields is very prominent. [0003] Weeds in direct seeded paddy fields are dominated by Gramineae weeds such as A. chinensis and barnyardgrass, which are abundan...
