Embodiment Construction

[0009] 1. Preparation of 10% Cyhalofop-Penoxsulam Oil Suspension Concentrate:

[0010] Weigh 8 kg of cyhalofop-methyl, 2 kg of penoxsulam, 8 kg of nonylphenol polyoxyethylene ether (NP-9) (dispersing wetting agent), 1 kg of propylene glycol (antifreezing agent), and xanthan gum (thickener) 1 kg, silicone defoamer (SAG612) 2 kg and methyl oleate (filler) 78 kg.

[0011] Mix cyhalofop-ethyl and penoxsulam thoroughly in the enamel stirring tank first, then add other raw materials, stir again for 30 minutes, and then stir again after sanding, that is, the finished product package is obtained, and the finished product meets or exceeds National mandatory index requirements for emulsifiable concentrate and oil suspension concentrate products.

[0012] 2. Application effect:

[0013] Get the control effects of 30 milliliters / mu, 40 milliliters / mu, and 50 milliliters / mu of the preparations made by the above method on rice barnyardgrass, daughter of a daughter, and sedge. The tes...

Abstract

The invention provides an oil suspension type herbicide containing cyhalofop-butyl and penoxsulam, relating to the technical field of production of pesticides. The oil suspension type herbicide is composed of effective components including the cyhalofop-butyl and the penoxsulam, wherein the cyhalofop-butyl accounts for 8% of the total mass of the herbicide; the penoxsulam accounts for 2% of the total mass of the herbicide; and the oil suspension type herbicide also contains 8% of a dispersion wetting agent, 1% of an anti-freezing agent, 1% of a thickening agent, 2% of a de-foaming agent and 78% of a filler. The oil suspension type herbicide contains the effective components including the cyhalofop-butyl and the penoxsulam, and can be applied to prevention and removal of 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 are good; the oil suspension type herbicide is safe to crops and has low cost and good prevention effect; and the herbicide composition has a stable chemical performance, is efficient and broad-spectrum, and has obvious broad-spectrum weeding and supplementary effect on prevention and removal objects.

Description

technical field [0001] The invention relates to the technical field of pesticide production. 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 abundant and early, and are the most harmful to rice, followed by broad...
