Embodiment 1

[0037] Example 1 An oil suspension concentrate containing fluroxypyr, nicosulfuron and atrazine at a mass concentration of 8% herbicides, nicosulfuron 2%, atrazine 5%, and fluroxyrpyr 1% , urea 0.5%, 1-dodecylazepan-2-one 2%, Nongru 1601 15%, turpentine-based vegetable oil 74.5%; its preparation steps and conditions are as follows: (1) According to the proportion, Add various raw materials into the stirring tank and stir for 30 minutes, and shear at the same time during the stirring process; (2) After stirring for 30 minutes, the material is ground by a sand mill, and the particle size D50 of the material shall not be greater than 8 microns; (3) After passing the grinding, transfer the material into a shear kettle and shear for 30 minutes to make an oil suspension. Sampling for item index testing.

Embodiment 2

[0038] Example 2 An oil suspension concentrate containing fluroxypyr, nicosulfuron and atrazine at a mass concentration of 70% herbicides, nicosulfuron 10%, atrazine 40%, and fluroxyrpyr 20% , urea 0.5%, 1-dodecylazepan-2-one 2%, agricultural milk 1601 15%, turpentine-based vegetable oil 12.5%. Sampling for item index testing. The steps and conditions of its preparation are the same as in Example 1

Embodiment 3

[0039] Example 3 An oil suspension concentrate of a herbicide containing fluroxypyr, nicosulfuron and atrazine at a mass concentration of 33%, nicosulfuron at 4%, atrazine at 20%, and fluroxyrpyr at 9% , urea 0.5%, 1-dodecyl azepan-2-one 2%, agricultural milk 1601 15%, turpentine-based vegetable oil 49.5%. Sampling for item index testing. The steps and conditions of its preparation are the same as in Example 1.

Abstract

The invention provides a herbicide containing fluroxypyr, nicosulfuron and atrazine. According to the invention, fluroxypyr, nicosulfuron and atrazine are used as main components, urea is used as a stabilizing agent, and 1-dodecyl azacycloheptane-2-one is used as a synergist; addition of 1-dodecyl azacycloheptane-2-one as the synergist substantially improves the effect of the herbicide. Turpentine-based vegetable oil used as a filling material is extracted from the timber of Chinese pine; the raw material for the filling material is natural and environment-friendly, resources are renewable, and the problem that usage of considerable organic solvents in pesticide preparations poses severe pollution to the environment is thoroughly overcome. Nicosulfuron, atrazine and fluroxypyr have obvious synergistic interaction, and integral drug effect of the herbicide is obviously better than a mixture of individual preparations of nicosulfuron, atrazine and fluroxypyr. Low dosage of the herbicide provided by the invention has a minimum control effect of 80.1% on grassy weeds, a minimum control effect of 86.9% on broad-leaf weeds and a comprehensive control effect of 83.5 to 99.9%; substantial synergy and reduction in drug cost are realized.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a herbicide containing fluroxypyr, nicosulfuron and atrazine and a preparation method. Background technique [0002] At present, closed weeding in corn fields in Northeast China generally has poor efficacy, especially the emergence of barnyardgrass, duckweed, Abutilon and other malignant weeds, which have a great impact on corn yield. Nicosulfuron: It can control annual and perennial grass weeds and some broad-leaved weeds in corn fields. Tests have shown that the weeds with strong sensitivity to the drug include Fuchsia, Setaria, wild oats, and Amaranthus reflexae; the weeds with moderate sensitivity include Polygonum benthamiana, Lilium, Purslane, Cocklegrass, Xanthium and velvet hemp and sedge; weeds with poor sensitivity mainly include quinoa, nightshade, duckweed, Kochia and ferret petals. Atrazine: It is a systemic selective pre-emergence and post-emergence herbicide....
