Abstract
The invention discloses a herbicide composition containing florasulam and 2,4-butyl ester. The effective components of the herbicide composition are florasulam and 2,4-butyl ester, and the mass fraction of the florasulam and the 2,4-butyl ester in the composition is 1:1 to 1:80. According to practical application, the composition disclosed by the invention can be prepared into a suspension concentrate, an oil suspension, wettable powder or a water dispersible granule, and is applied to control broadleaf weed in wheat fields; the effect of controlling broadleaf weed in wheat fields is obviously better than that of a single component used alone, and the herbicidal spectrum is increased. Besides, the consumption of the herbicide composition is reduced, the generation of herbicide resistance is delayed, and pollution to the environment is reduced.
Description
Technical field
The present invention relates to agricultural chemicals Herbicidal combinations and application thereof, is specifically the composite Herbicidal combinations of active ingredient with florasulam and 2,4-d butyl ester, is applied to the control of wheatland broad leaved weed.
Background technology
Chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because some weed killer herbicide kind large area are used separately, caused a lot of weeds to produce pesticide resistance.Meanwhile, while occurring due to weeds, grass is complicated, of a great variety mutually, and single variety is used can not effectively solve farmland weed, all can show defect in a certain respect.And the use that is mixed of variety classes weed killer herbicide, have herbicidal spectrum wide, promote preventive effect, delay the plurality of advantages such as weeds develop immunity to drugs, save time, saving of labor.
Florasulam (florasulam), belongs to triazolopyrimidine sulfonamides herbicide, has interior suction conduction, can conduct to weeds complete stool, thereby herbicide is thorough, can not recur.Efficacy stability at low temperatures, even still can guarantee to stablize drug effect in the time of 2 ℃, this point is that other weed killer herbicides are incomparable.Be mainly used in controlling broad leaved weed in wheat field, as clearvers, corn gromwell etc.
2,4-d butyl ester (2,4-D butylate), belongs to hormone herbicide, has stronger interior suction conductivity.Drug effect is high, and under very low concentrations, (< 0.01%) can suppress plant normal growth growth, occurs deformity, until dead.After being mainly used in seedling, cauline leaf is processed, and plate-out ability is good, and permeability is strong, easily enters in plant corpus, is difficult for by rain drop erosion, responsive to broadleaf weed, to cereal crop safety.Mainly be applicable to the gramineous crop fields such as wheat, barley, highland barley, corn, Chinese sorghum and gramineous forage grass ground, prevent and kill off broad leaved weeds such as broadcasting ma wormwood artemisia, lamb's-quarters, knotweed, leaf mustard, ion grass, chickweed, Amaranthus retroflexus, rule grass, meadow pine, denticulate ixeris herb, field thistle, Siberian cocklebur, field bindweed, kitchen garden, invalid to grassy weed.
By the screening of different pesticide species compounded formulas, select outstanding formula and can effectively improve the actual control efficiency to disease, worm, crop smothering, reduce dosage, reduce costs, delaying disease, worm, the drug-fast generation of crop smothering, is the important means of the upper disease of agricultural, worm, the crop smothering comprehensive regulation.The inventor conducts in-depth research the compounded formula screening of florasulam and 2,4-d butyl ester, finds florasulam and 2,4-d butyl ester carries out composite, in certain compound proportion scope, wheatland broad leaved weed is had to synergistic effect, after further study, completed the present invention.
Not yet find at present the relevant report that florasulam and 2,4-d butyl ester are composite and apply.
Summary of the invention
When the object of the invention is to solve prior art Pesticides single dose and using separately to wheat weeds easily develops immunity to drugs and actual control efficiency is poor problem, a kind of efficient, wide spectrum, economy, safety are provided, are conducive to the Herbicidal combinations of the wheat weeds comprehensive regulation.
Technical scheme of the present invention: a kind of florasulam and 2 contained, the Herbicidal combinations of 4-d butyl ester, active ingredient is florasulam and 2,4-d butyl ester, all the other are in agricultural chemicals, to allow to use and acceptable auxiliary element, florasulam and 2,4-d butyl ester in composition ratio of quality and the number of copies be 1:1～1:80.
