Embodiment 1

[0043] Embodiment 1 (5% penoxsulam · cyhalofop-methyl wettable powder)

[0044] Penoxsulam 2.5%, cyhalofop-methyl 2.5%, sodium butylnaphthalene sulfonate (wetting agent) 6%, sodium methylene dinaphthalene sulfonate (dispersant) 10%, white carbon black (filler ) 6%, and the balance is kaolin (filler). The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 5% penoxsulam·cyhalofop-methyl wettable powder.

Embodiment 2

[0045] Embodiment two (6% penoxsulam · cyhalofop-emulsion suspoemulsion)

[0046] Penoxsulam 1.5%, Cyhalofop-methyl 4.5%, Nongru 1601# (emulsifier) ​​15%, sodium p-methoxy fatty amidobenzenesulfonate (wetting agent) 7%, alkylphenol polyoxygen Vinyl ether formaldehyde condensate sulfate (dispersant) 5%, magnesium aluminum silicate (thickener) 1%, bentonite (thickener) 2%, xanthan gum (stabilizer) 0.1%, silicone (defoamer) agent) 0.4%, glycerol (antifreeze) 4%, and the balance is deionized water (medium). The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and mixed by high shear to prepare 6% penoxsulam·cyhalofop-emulsion suspoemulsion.

Embodiment 3

[0047] Example 3 (15% penoxsulam·cyhalofop-ethyl water dispersible granules)

[0048] Penoxsulam 2.5%, Cyhalofop-methyl 12.5%, Sodium lauryl sulfate (wetting agent) 6%, Polycarboxylate (dispersant) 5%, Sodium chloride (disintegrant) 2% , polyethylene glycol (binder) 3%, and the balance is kaolin (filler). Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 15% penoxsulam·cyhalofop-methyl water-dispersible granules.

Abstract

The invention discloses a pesticide compound containing penoxsulam and cyhalofop-butyl, and the application thereof; the compound comprises commonly used additive, penoxsulam and cyhalofop-butyl; the weight part ratio of the penoxsulam to the cyhalofop-butyl is 1:1 to 1:20; and the weight percentage of the total weight of the penoxsulam and the cyhalofop-butyl in the pesticide compound is 5 to 80percent. The invention is used for preventing and removing annual grassy weeds in a paddy field. The prevention effect of the invention has significant synergic or adding effect than the single dose,and the invention reduces the used dose of the pesticide, reduces the medication cost, prolongs the service life of the preparation and reduces the adverse impact of the pesticide on the ecological environment.

Description

technical field [0001] The pesticide composition of the present invention uses penoxsulam and cyhalofop-ethyl as active ingredients, and is used for controlling farmland weeds, especially for controlling annual weeds in paddy fields and the like. Background technique [0002] Penoxsulam is a conductive herbicide, which is absorbed by stems, leaves, shoots and roots, and amines can be quickly absorbed by the soil. Transmit to meristem through xylem and phloem, inhibit plant growth, make growth point chlorosis, 7-14 days after treatment, terminal buds turn red and necrotic, and plants die in 2-4 weeks; this agent is a strong acetolactate synthase inhibitor, The medicine appears slowly, and it takes a certain period of time for the weeds to gradually die. Broad-spectrum herbicide for paddy fields can effectively control barnyardgrass, stephenia and annual sedge weeds, and is effective against many broad-leaved weeds, and can also control bensulfuron-methyl-resistant weeds in p...
