Embodiment 1

[0019] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0020] Example 1:

[0021] a: cream

[0022] Mix 20% active component A and 20% active component B with 10% alkylphenol polyoxyethylene ether as emulsifier and 60% toluene as solvent in the reaction kettle.

[0023] b wettable powder:

[0024] With 20 parts of weight of effective composition and 2 parts of weight of sodium dodecylbenzenesulfonate as wetting agent, 10 parts of weight of granular white carbon black as adsorbent, 5 parts of weight of sodium dodecylbenzene sulfonate as dispersant Sodium lignosulfonate and 63 parts by weight of kaolin are ultrafinely pulverized in a jet mill.

[0025] c powder:

[0026] It is prepared by mixing 10 parts by weight of the effective composition and 90 parts by weight of talcum powder as an inert substance, and pulverizing them uniformly in a high-speed pulverizer.

[0027] d Granules:

[0028] It is prepared from 20 parts by ...

Embodiment 2

[0029] Example 2, the control effect of acetochlor and metazachlor mixed with weeds in rapeseed field

[0030] Location: Jiangsu, Xinyi

[0031] Application period: Weed 2-3 leaf stage investigation: 30 days after application: 2008

[0032]

[0033] Conclusion: The actual control effect of the mixture of acetochlor and metazachlor is higher than the expected theoretical control effect of their mixed use, and the herbicidal spectrum can be expanded at the same time, which proves that the mixed use of acetochlor and metazachlor has synergistic effect and expands the herbicidal spectrum.

Abstract

The invention provides a weedicide composition containing acetochlor, belonging to the improved weedicide compositions. The invention also provides a preparation method and application of the composition. The composition is a mixture of a compound (A) and metazachlor and can effectively prevent and kill off the annual grass weeds and broadleaf weeds in the rape fields. The control effect of the composition is obviously better than that of the single compound (A) or compound (B), thus substantially reducing the application dosage of various active substances.

Description

Technical field: [0001] The present invention relates to herbicidal compositions having improved properties. Background technique: [0002] The common name of compound (A) is acetochlor, and the chemical name is 2'-ethyl-6'-methyl-N-(ethoxymethyl)-2-chlorochloroanilide, which is an option Sexual herbicides. The herbicide can be widely used in soybean, corn, cotton, peanut, potato, sunflower, rape, sesame, radish, sugar cane, orchard, rice and leguminous, cruciferous, solanaceous, chrysanthemum and Umbelliferae and other crops Weeding in the field. Metazachlor can control gramineous weeds and dicotyledonous weeds in fields of rapeseed, soybean, potato, tobacco and transplanted cabbage. The main weeds controlled by metazachlor are annual gramineous weeds such as sagegrass, phoenix grass, wild oats, crabgrass, barnyardgrass, bluegrass, foxtail and amaranth, chamomile, chamomile, Polygonum, mustard, nightshade Broad-leaved weeds such as chickweed, nettle and mother-in-law ha...
