Abstract
The present invention relates to a cornfield herbicide containing butachlor, atrazine and metolachlor, and the herbicide is a suspoemulsion. The active ingredients of the herbicide are the butachlor, the atrazine and the metolachlor. The herbicide comprises the following components: 3-7% by weight of the butachlor, 18-26% by weight of the metolachlor, 15-25% by weight of the atrazine, 3-15% by weight of an emulsifier, 3-20% by weight of a surfactant, and 7-52% by weight of oils. The cornfield herbicide containing butachlor, atrazine and metolachlor effectively combines advantages of the metolachlor and the atrazine, so the herbicidal effect is improved, the residual activity is reduced, crop injury is reduced, the occurrence of herbicide resistance of weeds and community succession are delayed, the dosage and environmental pollution are decreased, and at the same time, labor and money are save, reducing the burden on farmers.
Description
Technical field
The present invention relates to a kind of composition pesticide of cornfield weeding, especially contain the corn field herbicide of butachlor, atrazine and isopropyl methoxalamine.
Background technology
Weeds and crops strive fertilizer, strive water, strive the soil, can cause agricultural output and quality to descend, affect harvest, it is harmful greatly to become agricultural production one, people use the chemical herbicide weeding always, but because the selectivity of most of weed killer herbicide own is not strong, and long-term use causes resistance weed easily, therefore need people that existing agricultural chemicals is improved or perfect, make it have better herbicidal effect.
Summary of the invention
Isopropyl methoxalamine is processing soil treatment agent before the selectivity bud, and the young shoot by plant is that the hypocotyl of unifacial leaf and coleoptile, dicotyledon absorbs upwards conduction, carries out dispenser before weeds germinate, and is mainly used in preventing and kill off grassy weed,
Atrazine is soil processing herbicide before the bud, but also behind the bud cauline leaf process, mainly absorb by plant root and upwards conduction, suppress the photosynthesis of plant, make it withered.Its herbicide spectrum is wider, can prevent and kill off multiple annual gramineae and broad leaved weed, especially corn is had preferably selectivity, but easily produces poisoning.
Butachlor is to inhale the conduction weed killer herbicide in the amide-type selectivity, and mainly the young shoot by weeds absorbs, and then conducts complete stool and works, before the bud and all can use seedling stage.Behind the plant absorbing butachlor, suppress in vivo and destroy protease, affect the formation of protein, suppress weeds young shoot and young root normal growth and grow, thereby make weeds dead.Be mainly used in annual gramineous weed and some broad leaved weed live or that prevent and kill off in the transplanting rice field.
Use separately the drug effect that runs into not strong in order to solve butachlor, atrazine and isopropyl methoxalamine, the problem that the herbicide spectrum is narrower, the present invention proposes the corn field herbicide that contains butachlor, atrazine and isopropyl methoxalamine, grassy weed can be prevented and kill off, broad leaved weed can be prevented and kill off again, also reduce simultaneously dosage, alleviated the poisoning to late stubble sensitive crop.
The present invention is achieved in the following ways: contain the corn field herbicide of butachlor, atrazine and isopropyl methoxalamine, this weed killer herbicide is suspension emulsion, and the effective ingredient of this weed killer herbicide is butachlor, atrazine and isopropyl methoxalamine, contains weight components:
Butachlor 3-7% isopropyl methoxalamine 18-26%
Atrazine 15-25% emulsifier 3-15%
Surfactant 3-20% oils 7-52%
Various components are mixed, in sand mill, be ground to the active ingredient particle diameter less than 3 μ m.
Surfactant among the present invention and emulsifier can increase stability, wetability and the permeability of complex weedicide.
The oils of complex weedicide of the present invention is mainly vegetable oil and mineral oil, as: machine oil, diesel oil, lubricating oil, soybean oil, levant cotton oil, peanut wet goods.
The invention has the beneficial effects as follows: this contains the corn field herbicide of butachlor, atrazine and isopropyl methoxalamine, effectively combine the advantage of isopropyl methoxalamine and atrazine, improved herbicidal effect, reduced residual activity, reduction is to the poisoning of crop, delays the generation of herbicide resistance and the succession of community, reduction dosage, environmental contamination reduction, save time simultaneously, laborsaving, economical, reduce farmer's burdens.
The invention will be further described below in conjunction with embodiment.
Embodiment one
Butachlor 3 isopropyl methoxalamines 22
Atrazine 20% emulsifier 15%
Surfactant 15% oils 25%
Embodiment two
Butachlor 4% isopropyl methoxalamine 25%
Atrazine 16% emulsifier 5%
Surfactant 5% oils 45%
Embodiment three
Butachlor 5% isopropyl methoxalamine 21%
Atrazine 15% emulsifier 3%
Surfactant 6% oils 50%.
