Abstract
The invention relates to a weeding composition containing diclosulam. The weeding composition containing diclosulam comprises the following components by weight percentage: 0.5-30% of diclosulam and 2-50% of atrazine. The weeding composition containing diclosulam is mainly used for preventing and treating annual broad leaf weeds in wheat and corn fields, is remarkable in a weeding effect, wide in weeding spectrum and safe on crops and has obvious practicability.
Description
Technical field
The present invention relates to a kind of herbicidal composition.The herbicidal composition that specifically contains diclosulam and atrazine.
Background technology
Diclosulam (diclosulam) is the new high-efficiency weed killer herbicide that before a kind of suitable soybean, Peanut Fields seedling, planting soil is processed, this composition is acetolactate synthestase (ALS) inhibitor, can be absorbed fast by root and cauline leaf by weeds, and play a role.This composition is mainly used in preventing and kill off broad leaved weed.
Atrazine (atrazine) is before interior suction selectivity seedling, herbicide after seedling.Root absorption is main, and cauline leaf absorbs seldom.The same Simanex of herbicide effect and selectivity, easily by rainwater drip washing to soil than deep layer, also effective to some dark root grass, but easily produce poisoning.Lasting period is also longer.The scope of application is applicable to corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land and prevents and kill off lady's-grass, barnyard grass, green foxtail, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, and some perennial weed is also had certain inhibitory action.Atrazine can effectively be prevented and kill off the broad leaved weeds such as the annual gramineous weeds such as wind grass, mouse tail amur foxtail, wild oat, lady's-grass, barnyard grass, annual bluegrass, green foxtail and amaranth grass, german chamomile, knotweed, chickweed, nettle, Veronica.
Summary of the invention
The object of the invention is to the shortcoming for prior art, provide that a kind of herbicidal effect is good, the lasting period is long, consumption is few, dispenser Herbicidal combinations easily.
The technical scheme that realizes the object of the invention is:
A kind of herbicidal composition contains diclosulam and atrazine.
Described herbicidal composition contains diclosulam 0.5%～30%, atrazine 2%～50%.
Described Herbicidal combinations, but microemulsion, aqueous emulsion, suspending agent, wetting powder, effervescent tablet, water-dispersible granules dispersed oil suspending agent can be made, and above-mentioned preparation can be prepared with general method.
Described herbicidal composition is mainly used in preventing and treating wheat and maize Tanaka's annual broadleaf weed.
Embodiment
Following instantiation is in order to further describing the present invention, but the present invention absolutely not only only limits to following these embodiment.In formula, percentage all is weight percentage, and the former medicine that uses and auxiliary agent are other producers and buy.Formulation examples is as follows:
Embodiment 1 (12% microemulsion)
According to the micro-emulsion formulation requirement, active ingredient, solvent, emulsifier are added be stirred to homogeneous transparent in still, after add purified water, continue to be stirred to and form homogeneous transparent liquid.
Embodiment 2 (33% aqueous emulsion)
According to the water emulsion formula requirement, active ingredient and solvent are added be stirred to dissolving in still and form transparent homogeneous liquid, add emulsifier, purified water, add emulsification in the high-shear emulsifying still, make aqueous emulsion.
Embodiment 3 (30% suspending agent)
According to the formula requirement, take water as medium, active ingredient, wetting agent, dispersant, thickener, defoamer etc. are added grind in sand mill, make suspending agent.
Embodiment 4(25% suspending agent)
According to the formula requirement, take water as medium, active ingredient, wetting agent, dispersant, thickener, defoamer etc. are added grind in sand mill, make suspending agent.
Embodiment 5 (32% wetting powder)
According to the formula requirement, with active ingredient, dispersant, wetting agent, filler mix all with after join in ultrafine crusher, make wetting powder after pulverizing.
Embodiment 6 (14% effervescent tablet)
According to the requirement of effervescent tablet formula, former medicine and carrier, acid source, carbon dioxide source, wetting dispersing agent, binding agent, disintegrant, mix lubricant is even, through after meal, again mix, through after air flow super, material is added multiple tablet press machine compacting in flakes.
Embodiment 7 (50.5% water dispersible granules)
According to the formula requirement, active ingredient, wetting agent, dispersant, adhesive, filler etc. are fully mixed in the ratio of formula, after ultra-fine pulverizer disintegrating, add appropriate purified water, make water dispersible granules through kneading, granulation, drying, screening.
Embodiment 8 (40% water dispersible granules)
According to the formula requirement, active ingredient, wetting agent, dispersant, adhesive, filler etc. are fully mixed in the ratio of formula, after ultra-fine pulverizer disintegrating, add appropriate purified water, make water dispersible granules through kneading, granulation, drying, screening.
Embodiment 9 (but 10% dispersed oil suspending agent)
But according to the requirement of dispersed oil suspending agent formula, take methylated vegetable oil as medium, that active ingredient and dispersant, wetting agent, thickener, emulsifier for mixing is even, put into sand mill and grind evenly, but obtain the dispersed oil suspending agent.
Embodiment 10 (but 21% dispersed oil suspending agent)
But according to the requirement of dispersed oil suspending agent formula, take methylated vegetable oil as medium, that active ingredient and dispersant, wetting agent, thickener, emulsifier for mixing is even, put into sand mill and grind evenly, but obtain the dispersed oil suspending agent.
In order to verify whether complex preparation has synergistic effect, the activity of medicament to field thistle, Amaranthus retroflexus after we adopt the check of Colby method mixed, grow to the 3-5 leaf in weeds and carry out during the phase, with after the former medicine dissolving of diclosulam and atrazine, composite and single dose is diluted to the liquid of finite concentration gradient with these.Adopt the Potter spray tower to processings of spraying of weeds cauline leaf, each processes four repetitions, and each repeats to be sprayed to blade surface by medicament moistening even (spray time is 30s approximately).Be treated to blank with the clear water that does not contain medicament.Adopt absolute value investigation method investigation records activity of weeding weeds fresh weight after 21 days, calculate the fresh weight preventive effect that each is processed, calculate E
0And E, work as E
0-E〉10% for synergistic effect; Work as E
0-E＜-10% is antagonism; Work as E
0One E value is addition between ± 10%.
The activity of weeding of table 1 diclosulam and the different proportionings of atrazine
The co-toxicity effect of table 2 atrazine proportionings different from diclosulam to field thistle
The co-toxicity effect of table 3 diclosulam proportionings different from atrazine to Amaranthus retroflexus
Can obviously find out when diclosulam and atrazine, synergistic effect is in various degree arranged all from above-mentioned data, illustrate that the scope of diclosulam 0.5%～30% and atrazine 2%～50% is interior composite, can reach the effect of synergy.
Atrazine and diclosulam complex preparation have not only improved drug effect, and have extended the lasting period, illustrate that all there have been significant raising the quick-acting of this complex preparation and lasting period than single dose, use this complex preparation, can greatly reduce the use cost of peasant household, enlarge the herbicide spectrum, increase economic efficiency.
