Abstract
The invention relates to a weedicide composition containing glyphosate and carfentrazone-ethyl, which comprises active ingredients, assistants and stuffing, wherein the active ingredients are glyphosate and carfentrazone-ethyl which can be made into a suspending agent, wettable powder, water-dispersible granules and other conventional preparations; and the weight proportion of the glyphosate to the carfentrazone-ethyl is 1:1-20:1. The weedicide composition of the invention overcomes the defect of single ingredient in the prior art and obviously enhances the efficiency. The weedicide composition can prevent and kill most gramineae and broadleaf weeds in bare place, and has the characteristics of quick acting, broad spectrum, low residual, less consumption and the like.
Description
Technical field
The present invention relates to a kind of uncultivated area herbicidal composition.
Background technology
A kind of organophosphorus herbicide of glyphosate (glyphosate), formal name used at school N-(adjacent acyl group methyl) glycine.The herbicidal properties of glyphosate is to be found by U.S. D.D. Baird etc. in 1971, by Monsanto Company's Development and Production, has become the important kind of world's weed killer herbicide to the eighties in last century, and its structural formula is:
Molecular formula: C
3H
8NO
5P molecular weight: 169.07
Glyphosate is a kind of natural disposition inner sucting herbicide that goes out, and broad weed-killing spectrum absorbs and the conduction complete stool by the weeds cauline leaf, makes weeds withered.Glyphosate is prevented and kill off effect to the plant of section more than 40, comprises plants such as unifacial leaf and dicotyledonous, annual and perennial, draft and shrub, and is very strong to the underground organization destructive power of perennial dark root weeds, can reach the general agricultural machinery degree of depth that is beyond one's reach.Be applicable to that crops such as orchard, tea place, mulberry field, forest, farmland are to use fallow land, limit, field, road, railway etc., but glyphosate is for the sealing process of germination seed is not bad in the soil, and the preventive effect to broad leaved weed is lower than grassy weed, the present invention is intended to find a kind of good and can suppress the medicament of seed germination to the broad leaved weed preventive effect, with glyphosate and this composite reagent, grassy weed, broad leaved weed can be effectively prevented and kill off, and the sprouting of weed seed can be suppressed for a long time.After using such complex preparation, the weeds plant can be effectively killed, the sprouting of weed seed can be suppressed again, guarantee need not use other weed killer herbicides in 65-90 days.
Azoles humulone (carfentrazone-ethyl) is a kind of selectivity contact killing type weed killer herbicide, CAS number: 128621-72-7, chemical name: ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxygen-1H-1,2, the 4-triazol-1-yl]-the 4-fluorophenyl } ethyl propionate, structural formula is as follows:
Molecular formula: C

The azoles humulone is by inhibition protoporphyrin oxidase, thereby makes the film division.On cereal crop, use, be used for leaf surface treatment behind the seedling, remarkable to multiple broad leaved weed preventive effect, the broad leaved weed conduction is obstructed and very fast withered death.To cereal crop safety such as wheat, corns.To having special efficacy, to succession crop safety in long-term weeds of using sulfonylureas weed killer herbicide area to develop immunity to drugs.
By the Searches of Patent Literature, the domestic composite patent that does not have glyphosate and azoles humulone at present, therefore, this herbicidal composition has certain novelty.The present invention not only improves two kinds of composite reagents drug effect but also has prolonged the lasting period, has especially strengthened the preventive effect to some resistant weed, reduces peasant's use cost greatly.
Summary of the invention
The objective of the invention is to the shortcoming at prior art, provide a kind of and can prevent and kill off the herbicidal composition of single, double cotyledon weeds simultaneously, herbicidal effect is good, the lasting period is long, safety, wide spectrum.
The technical scheme that realizes the object of the invention is:

In order to verify whether complex preparation has synergistic effect, we adopt the check of Gowing method to use the activity of back medicament to chickweed, shepherd's purse with.Weeds are grown seedlings in the artificial culture case with small flower, every basin is selected 10 strain weeds of the same size, and all the other weeds are rejected.The former medicine dissolving back of glyphosate and azoles humulone is become these composite and single dilution agents with 0.1% Tween 80 the soup of finite concentration gradient.Adopt the Potter spray tower to processings of spraying of weeds cauline leaf, each handles 3 repetitions, and each repeats to be sprayed to blade surface by medicament moistening even (the about 30s of spray time).Be treated to blank with the clear water that does not contain medicament.Each processing is moved to the artificial culture case, 28 ℃, to cultivate under the 25000Lux condition, 21 days " Invest, Then Investigate " record activity of weeding weeds fresh weights calculate the fresh weight preventive effect that each is handled, and calculate theoretical survival rate E
0With actual survival rate E.Work as E
0-E＞10% is synergistic effect; Work as E
0-E＜-10% is an antagonism; Work as E
0-E value is addition between ± 10%.
E=(contrast fresh weight-processing fresh weight)/contrast fresh weight * 100%
E
0＝X+Y(100-X)/100
E wherein
0The theory of using with for glyphosate and azoles humulone suppresses growth percentage, and the percentage of the inhibition growth that X uses for the glyphosate list, Y are the percentage of the inhibition growth used of azoles humulone list.
The activity of weeding of table 1 glyphosate and the different composite proportionings of azoles humulone
The different proportionings with the azoles humulone of table 2 glyphosate are to the co-toxicity effect of chickweed
The different proportionings with the azoles humulone of table 3 glyphosate are to the co-toxicity effect of Amaranthus retroflexus
Data in above table can obviously find out when glyphosate and azoles humulone are composite, synergistic effect is in various degree arranged all, illustrate that glyphosate and azoles humulone are composite in 1: 1～20: 1 scopes, can reach the effect of synergy.From the table data as can be seen, glyphosate and azoles humulone proportioning are more obvious a synergy in 1: 1 to 2.5: 1.
Therefore, compare with single agent, glyphosate and the synergy of azoles humulone complex preparation are obvious, can reduce dosage, enlarge and kill the grass spectrum, and obviously improve the preventive effect of antagonism weeds.
