Embodiment 1

[0020] Embodiment 1: 14wt% water emulsion

[0021] Ratio (wt%): quizalofop-p-ethyl 10%, chlorpyrazosulfuron-methyl 2.5%, garlic oil 1.5%, No. 150 industrial solvent oil 8%, Nongru No. 600 5%, Nongru NP-103%, poly Vinyl alcohol 2wt%, ethylene glycol 3wt%, water balance.

[0022] Preparation method: Mix quizalofop-pyl-ethyl, garlic oil, No. 150 industrial solvent oil, Nongru No. 600 and Nongru NP-10 to dissolve them into a uniform oil phase; mix clopyrazosulfuron-methyl, polyvinyl alcohol and Propylene glycol is added to water and mixed together to form a uniform water phase; under high-speed stirring, the water phase is added to the oil phase to form a well-dispersed water emulsion.

[0023] How to use: This product should be applied after the cotton seedlings, at the 3-5 leaf stage of annual grass weeds, and pay attention to spray evenly on the stems and leaves of the weeds. According to 50ml / hm 2 Dosage (dosage of active ingredients: 7ml / hm 2 ), add water 60L / hm 2 After ...

[0028] Proportion (wt%): quizalofop-p-ethyl 18%, chlorpyrazosulfuron-methyl 4%, garlic oil 3%, No. 150 industrial solvent oil 12%, Nongru No. 600 7%, Nongru NP-104%, poly Vinyl alcohol 3wt%, ethylene glycol 5wt%, water balance.

[0029] Preparation method: with embodiment 1.

[0030] How to use: according to 30ml / hm 2 Consumption, all the other are with embodiment.

Embodiment 3

[0031] Embodiment 3: 15wt% suspoemulsion

[0032] Proportion (wt%): quizalofop-p-ethyl 10%, chlorpyrazosulfuron-methyl 3%, garlic oil 2%, industrial solvent oil No. 150 8%, Nongru No. 500 6%, Nongru No. 700 2%, poly 2% by weight of vinyl alcohol, 3% by weight of ethylene glycol, 2% of sodium dodecylsulfonate, 0.2% of organic silicone, and the balance of water.

[0033] The preparation method is: mix quizalofop-pyl-ethyl, garlic oil, No. 150 industrial solvent oil, Nongru No. 500 and Nongru No. 700 to dissolve them into a uniform oil phase; , Sodium lauryl sulfonate, organosilicone and water are mixed to make water suspension; then the prepared oil phase and water suspension are sheared and dispersed evenly to make suspoemulsion.

Abstract

The invention discloses herbicide special for a cotton field. The herbicide is formed by mixing quizalofop-p-ethyl, halosulfuron-methyl and garlic oil. The herbicide has a better killing effect on gramineous weeds, cyperaceae weeds and broadleaf weeds, and drug harm to crops is relieved.

Description

technical field [0001] The invention relates to a herbicide, in particular to a special herbicide for cotton fields, and belongs to the technical field of agricultural production. Background technique [0002] Cotton is an important economic crop in my country. Cotton is widely distributed in my country and is planted from south to north. The total sown area of ​​cotton in my country is about 75 million mu. The main factors affecting cotton yield are insect damage and weed damage. At present, herbicides commonly used in cotton fields are: trifluralin, acetochlor, etc. Trifluralin is a herbicide with long residual effect, which is easy to cause phytotoxicity after cropping, and it needs to be mixed with soil when used, which is time-consuming and labor-intensive, and it will also cause swelling of cotton roots after use; And it requires higher soil moisture. At the same time, due to the continuous use of herbicides in cotton fields for many years, the problem of phytotoxi...
