Description

A kind of Herbicidal combinations

Technical field

The invention belongs to pesticide field more particularly to a kind of Herbicidal combinations and a kind of undesirable plant growths of control Method.

Background technique

World food production is huge because of disease, worm, crop smothering loss every year, and the entire season of growth of crop nearly all will receive respectively The infringement of kind weeds, Weed infestation are also the key factor for restricting crop yield.Therefore, the prevention and treatment of agricultural weed is always agriculture It is concerned about the most and important problem in industry production.

Protecting crops from the weeds for inhibiting crop growth and the infringement of other vegetation is asking of persistently occurring in agricultural Topic.To solve this problem, the chemicals of many control weed growths and chemicals use in business.

Rice is one of world's staple food crop, in the world nearly half population, including almost entire East Asia and Southeast Asia Population, be all food with rice, production is throughout each continent in addition to the South Pole, and in China, rice is also that most important grain is made Object.China's rice growing area accounts for the 1/4 of national cereal crops, and yield then accounts for more than half.No matter cultivated area and yield, It all ranks first in China cereal crops.

The prevention and treatment of agricultural weed is always to be concerned about the most in agricultural production and important problem.The entire season of growth of crop It nearly all will receive the harm of various weeds.All rice workspaces in China always have a large amount of weeds, and weeds in paddy field type is very More, various regions are maximum with barnyard grass occurring area and harm in these weeds because the factors weeds such as weather, soil type is different, also There are the hazard areas such as difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, semen euphorbiae, bog pondweed, Monochoria korsakowii and severity to take second place.

Halosulfuronmethyl (Halosulfuron-methyl, CAS NO.100784-20-1) belongs to sulfonylurea herbicide, pure Product are white powdery solids, 175.5-177.2 DEG C of fusing point, are insoluble in water, in most solvents such as n-hexane, acetone, dichloromethane Alkane, toluene, the solubility in ethyl acetate equal solvent are also smaller.Halosulfuronmethyl is the chloro- 5- of 3- [[[(4,6- dimethoxy -2- Pyrimidine radicals) amino] carbonyl]] amino] sulfonyl] -1- methyl-1 H- pyrazoles -4- carboxylate methyl ester adopted name.Halosulfuronmethyl For sulfonylurea rice field selective inner-adsorption conduction-type herbicide.Halosulfuronmethyl is mainly absorbed by root system, can also be passed through Cauline leaf absorbs, and shifts rapidly in weeds plant body, inhibits weed growth, and weeds are gradually dead.The weeding of halosulfuronmethyl is living Property is described in The Pesticide Manual, Fourteenth Editioni, 2006.Halosulfuronmethyl controls rice, jade Many broad-leaveds and nut nutgrass flatsedge in rice, sorghum, sugarcane, nut and turf.

The use of chemical herbicide is the one of the important signs that of agricultural modernization, and in recent years, the sales volume of herbicide increases year by year Add, administration area also expands year by year.But as the large area of numerous herbicide kinds persistently uses, many is led to the problem of, Such as Weed Resistance problem starts to show especially, the resistance problem of especially elder weed is especially prominent；In addition, herbicide single dose effect side Formula is single, the lasting period is short etc..Therefore, it is wide, selective strong and lesser to herbicide resistance pressure that presently, there are weeding ranges The urgent need of release weedicide and combinations thereof.

But as numerous herbicide kinds are persistently used in paddy field large area, also lead to the problem of many: (1) miscellaneous Careless resistance is prominent, wherein more prominent with resistance of the barnyard grass to herbicides such as propanil, butachlors, there are also sedge weeds to sulphonyl The resistance problem of carbamide herbicides also gradually appears；(2) elder weed and perennial weeds harm become major issue, especially Above the average age for marriage barnyard grass and Cyperaceae perennial weeds are more prominent；(3) effect of herbicide kind is single, and the lasting period is short.

In some cases, have shown that herbicidal active component is more effective in combination compared with being administered alone, this claims For " synergistic effect ".Synergistic effect is two or more factor interactions, so that effect ratio is based on applying respectively upon combination Effect desired by response with each factor is good.

CN103392724A discloses the purposes that a kind of cassava field herbicide composition is used to prevent and treat the rhizome of nutgrass flatsedge, and described removes Careless agent composition is the ternary combinations of herbicides by halosulfuronmethyl, Oxyfluorfen and acetamide-group herbicides for active constituent Object, acetamide-group herbicides are one of butachlor, propisochlor, S-metolachlor.

Evaluation to the mixed synergistic effect for applying middle display of two or more herbicidal active components is to be based on “CalculationSynergistic and Antagonistic Response of Herbicide Combinations” What Colby ' s method described in (Weeds15/1 (1967), S.R.Colby) determined.

In formula, X is (a) when using a single dose to the fresh weight inhibition rate of target weeds.

Y is (b) when using a single dose to the fresh weight inhibition rate of target weeds.

E₀To the theoretical value of target weed fresh weight inhibition rate for (a) and when (b) two kinds of pharmacy mix.

To the measured value of target weed fresh weight inhibition rate when E is (a) and (b) two kinds of pharmacy mix.

If the actual control of weeds rate (E) observed in biologic test is more than to be calculated using Colby ' s method Desired value (the E arrived₀), then it represents that the effect of Herbicidal combinations is greater than the summation of each agent effectiveness, it means that composition has Synergistic effect.
