Abstract

The herbicide compounded with benzene thiazole humulone and rimsulfuron, is related to technical field of herbicide production, active ingredient is made up of benzene thiazole humulone and rimsulfuron, using suspending agent or wettable powder as product forms.Composition herbicide raw material weight per distribution ratio is benzene thiazole humulone 1~15%, and rimsulfuron 1~50%, auxiliary agent content is 2~25%, and filer content is 10~96%.It is a kind of weeding agricultural chemical compositions, shows the efficient, herbicidal performance of wide spectrum, mainly applied in corn field annual grassy weeds is prevented and kill off, crop is had no adverse effects.

Description

The herbicide compounded with benzene thiazole humulone and rimsulfuron

Technical field

The present invention relates to herbicidal composition technical field.

Background technology

Corn is the main food long-term cropping in China, and national corn seeding area is stablized at 4.5 hundred million mu always for many years Left and right.Corn planting distribution is wide, there is two kinds of planting patterns of spring maize and summer corn.Field weed community is because of local natural conditions With farming feature and it is different, can substantially be divided into 6 crop smotherings such as northeast Spring Maize weeds area, Huang-Huai-Hai corn field of summer weeds area Area.Corn field weed occur it is universal, main weeds have lady's-grass, barnyard grass, green bristlegrass, eleusine indica, Amaranthus retroflexus, purslane, acalypha copperleaf, Rhizome of nutgrass flatsedge etc..Chemical herbicide has point of steriland herbicide and selective herbicide at present, and selective herbicide has soil again Inorganic agent and cauline leaf process agent are not, and have point of contact-type and conduction type.Different components, the herbicide of different cultivars, it is killed Grass spectrum, adaptability and the sensitiveness to crop have difference, but in the market corn field herbicide is multifarious, and peasant does not often know How road selects, and many peasant households, which falsely drop, misuses herbicide, and unnecessary harm is caused to corn growth.So understand herbicide Species and it is proper use of be corn control of weeds key.

Benzene thiazole humulone is a kind of using PPO as the ultra high efficiency of action target, low toxicity, low-residue green herbicide, be can be used for Corn field prevents and kill off a variety of broad leaved weeds.

Rimsulfuron is a kind of special efficacy selective herbicide for being currently used primarily in corn weeding, for preventing and kill off in milpa Annual or perennial grass family and broad leaved weed, as creeping thistle, iron shepherd's purse, the rhizome of nutgrass flatsedge, curled dock, johnson grass, wild oat, Digitaria ischaemum (Schreib.) Schreib. Ex Mubl, barnyard grass, Itanlian rye, piemarker, Amaranthus retroflexus, clearvers, corn poppy, chickweed.To early stage after annual grassy weeds bud Using it is further preferred that, recommend 5~15g of dosage active ingredients/hm.For corn weeding；It is most safe to spring maize to corn safety.Sulfone Half-life period of the Sulfometuron Methyl in corn is only 6h, and when being handled with 2~4 times of recommended dose, corn is still very safe.Pressed in corn field 5~15g of recommended dose (a.i.)/hm2 [every mu 0.33~1.09 (a.i.)].During use, succession crop is had no adverse effects.

The content of the invention

The purpose of the present invention is for a variety of deficiencies existing for current wide spectrum, highy potent herbicide shortage and existing herbicide Part, there is provided one kind has the efficient, herbicide of broad spectrum weeding function using suspending agent or wettable powder as formulation.

The present invention is made up of active ingredient and auxiliary agent, filler, and active ingredient is made up of benzene thiazole humulone and rimsulfuron, benzene Thiazole humulone accounts for the 1~15% of herbicide gross mass, and rimsulfuron accounts for the 1~50% of herbicide gross mass, and it is total that auxiliary agent accounts for herbicide The 2~25% of quality, filler account for the 10~96% of herbicide gross mass.

The present invention is compounded using benzene thiazole humulone and rimsulfuron, has efficient, broad spectrum weeding function, while expand and remove Careless scope, the weeds such as corn field lady's-grass, moleplant seed, polygonum flaccidum, cyperus iria, Amaranthus retroflexus are shown with excellent preventive effect, more than benzene The use of two single dose kinds of thiazole humulone and rimsulfuron.To crop safety, cost is low, preventive effect is good.Prove after tested, this hair Bright herbicidal composition chemical property is stable, high-efficiency broad spectrum, and obvious broad-spectrum weed-killing and complementary work are shown to control object With.

Advantages of the present invention：Benzene thiazole humulone and rimsulfuron both combination of active principles use, expand weeding model Enclose and herbicidal effect.Determined through experiment：Benzene thiazole humulone is used to prevent and kill off a variety of broad-leaved resistant weeds, but grassy weed is prevented Imitate poor.And although rimsulfuron is a kind of broad-spectrum herbicide, annual to corn field after seedling and perennial grassy weed prevents Except all having good effect.Therefore benzene thiazole humulone and rimsulfuron composition endanger institute to corn field for main resistant weed The wide spectrum and synergistic effect reached is the most notable.Secondly use cost reduces, and benzene thiazole humulone and rimsulfuron single dose make at present Higher with cost, it is not again fine that effect, which is used alone, in low dosage, therefore preventive effect is applied in combination in benzene thiazole humulone and rimsulfuron Improve, reduce agriculture sheet again.

Further, benzene thiazole humulone of the present invention accounts for the 3% of herbicide gross mass, and rimsulfuron accounts for the total matter of herbicide The 12% of amount.

The benzene thiazole humulone accounts for the 8% of herbicide gross mass, and rimsulfuron accounts for the 12% of herbicide gross mass.

The formulation of product of the present invention is wettable powder or suspending agent.

When formulation is wettable powder, described auxiliary agent auxiliary agent is made up of dispersant 1~20%, wetting agent 1~5%, Dispersant uses lignosulfonates, NNO, one kind of pull open powder or any two or three of mixture.Wherein, lignin sulfonic acid Salt selects calcium lignosulfonate or sodium lignin sulfonate；Wetting agent uses sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate.Filler is adopted It is silica-based using clay, kaolin and diatom with a kind of or mixture in silica-based, precipitated calcium carbonate, white carbon Soil etc..

When formulation is suspending agent, described auxiliary agent is by dispersion moisture agent 1~15%, antifreeze 0.3~3%, thickener 0.4~5%, defoamer 0.3~2% forms, and dispersion moisture agent uses polyoxyethylene tri-styryl phosphenylic acid salt, or alkylnaphthalene One kind or mixture in sulfonate, or APES；Antifreeze uses alcohols using antifreeze, from the third two Alcohol or glycerine or ethylene glycol；Thickener uses xanthans or aluminium-magnesium silicate；Defoamer uses organic silicon defoamer；Filler is adopted Use water.
