Abstract
The invention relates to a nicosulfuron-and-atrazine-containing weeding composition. The composition is an oil suspending agent, which contains the following components in percentage by weight: 3 percent of nicosulfuron, 20 percent of atrazine, 10 percent of emulsifier, 20 percent of surfactant and 47 percent of oil. The weeding composition effectively combines the advantages of the nicosulfuron and the atrazine, improves the weeding effect, reduces the residual activity, reduces the herbicide damage to crops, delays the herbicide resistance of weeds and community succession, reduces the using amount of herbicides, reduces environmental pollution, is time-saving, labor-saving and money-saving and alleviates the burden on farmers.
Description
Technical field
The present invention relates to a kind of composition pesticide of weeding, especially a kind of Herbicidal combinations that contains nicosulfuron and atrazine.
Background technology
Nicosulfuron is a herbicides special behind the corn field seedling, grassy weed in the corn field and part broad leaved weed there are significant preventive effect, good to the corn safety, but because nicosulfuron is mainly active high to grassy weed, only good to part broad leaved weed activity, it is narrower that it kills the grass spectrum.
Atrazine is before the interior suction selectivity seedling, herbicide after seedling.Root absorption is main, cauline leaf absorbs seldom, be applicable to corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land, Cruciferae, pulse family weeds and some perennial weed all there is certain inhibitory action, and easily by rainwater drip washing to soil than deep layer, also effective to some dark root grass, but easily produce poisoning, the lasting period is also longer.
Summary of the invention
Use the problem that runs into separately in order to solve nicosulfuron and atrazine, the present invention proposes a kind of Herbicidal combinations that contains nicosulfuron and atrazine, this Herbicidal combinations effectively combines the advantage of nicosulfuron and atrazine, improved herbicidal effect, reduced residual activity, reduced poisoning crop, delay the drug-fast generation of weeds and the succession of community, reduction dosage, reduce environmental pollution, save time simultaneously, laborsaving, economical, reduce farmer's burdens.
The present invention realizes in the following manner: a kind of Herbicidal combinations that contains nicosulfuron and atrazine, and said composition is an oil-suspending agent, contains following composition by weight:
Nicosulfuron 3% atrazine 20%
Emulsifier 10% surfactant 20%
Oils 47%
Various components are mixed, in sand mill, be ground to the active ingredient particle diameter less than 3 μ m.
Surfactant in the composition of the present invention and emulsifier can increase stability, wetability and the permeability of composition.
The oils of composition 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 a kind of Herbicidal combinations that contains nicosulfuron and atrazine, effectively combine the advantage of nicosulfuron and atrazine, improved herbicidal effect, reduced residual activity, reduction delays the drug-fast generation of weeds and the succession of community, reduction dosage to the poisoning of crop, reduces environmental pollution, save time simultaneously, laborsaving, economical, reduce farmer's burdens.
The invention will be further described below in conjunction with embodiment.
Embodiment 1
The corn 3-4 leaf phase, weeds 2-3 leaf phase dispenser, 30 days investigation strain preventive effect results are as follows behind the medicine
Test shows: it is suitable with each single agent preventive effect that nicosulfuron and show go to Tianjin to use with, and to crop safety.
Embodiment two
The corn 3-6 leaf phase, weeds 2-5 leaf phase dispenser, 35 days investigation strain preventive effect results are as follows behind the medicine
Test shows: nicosulfuron and show go to Tianjin to use with can to enlarge to kill the grass spectrum, improve the preventive effect to broadleaved herb, and to crop safety.
Claims (2)
1. a Herbicidal combinations that contains nicosulfuron and atrazine is characterized in that, said composition is an oil-suspending agent, contains following composition by weight: nicosulfuron 3%, atrazine 20%, emulsifier 10%, surfactant 20%, oils 47%.
2. according to the described a kind of Herbicidal combinations that contains nicosulfuron and atrazine of claim 1, it is characterized in that: oils is mainly vegetable oil and mineral oil.
