Embodiment Construction

[0015] Preparation and application effect of 5% penoxsulam·saflufenacil EC:

[0016] Weigh 2 kg of penoxsulam, 3 kg of saflufenacil, 10 kg of Nongru 500 (emulsifier), and 85 kg of xylene (solvent).

[0017] After fully mixing in the enamel stirring tank, add the emulsifier in the additive, and stir again for 30 minutes. After passing the inspection, the finished product can be packaged. The finished product meets or exceeds the national compulsory index requirements for emulsifiable oil products.

[0018] The control effects of 25 milliliters / mu, 37.5 milliliters / mu, and 50 milliliters / mu of the preparations made according to the above ratio to paddy barnyardgrass, stephenia, and sedge are more than 90%, which is better than single use.

Abstract

The invention provides a synergistic missible oil herbicide taking penoxsulam and pyribenzoxim as effective components, relating to the technical field of production of pesticides. According to the synergistic missible oil herbicide, the penoxsulam and the pyribenzoxim are compounded so that the synergistic missible oil herbicide has efficient and broad-spectrum weeding effects, and the weeding range is expanded; the synergistic missible oil herbicide has good prevention and treatment effects 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 synergistic missible oil herbicide has no bad influences on crops and can be used by more than two single-dosage varieties including the penoxsulam and the pyribenzoxim.

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-seeding paddy fields are dominated by gramineous weeds such as barnyardgrass, which emerge early and are the most harmful to rice, followed by broad-leaved weeds such as berm...
