Description
Technical field
The present invention relates to a kind of Herbicidal combinations of corn field, be made up of active component nicosulfuron, florasulam and atrazine and auxiliary agent, belong to technical field of compounded pesticide.
Background technology
China's corn planting mainly concentrates on northeast, North China and southwest, roughly forms a plagioclase maize culture band from northeast to southwest.Wherein Heilungkiang, Jilin, Liaoning, Hebei, Shandong, Shanxi, Henan, Shaanxi, Sichuan, Guizhou, Yunnan, Guangxi etc. are main provinces and regions.Corn field weed occurs general, and weeds are of a great variety, mainly contain broad leaved weeds as kitchen garden, Amaranthus retroflexus, acalypha copperleaf, lamb's-quarters, piemarker, Siberian cocklebur, black nightshade, field bindweed, field thistle, dayflower etc.; Grassy weed is as lady's-grass, green foxtail, eleusine indica, barnyard grass, Bermuda grass etc.; Sedge weed is as the rhizome of nutgrass flatsedge etc.Weeds and crop fight for moisture, nutrient, illumination and space, affect crop normal growth, even can cause Severe Reduction.Chemical weed control economy, effective, laborsaving, but because most of weed killer herbicide herbicide spectrum own is limited, and Long-Time Service easily causes the generation of Weed Resistance, and by herbicide mixtures different for the mechanism of action, herbicidal effect and herbicide spectrum can be improved, delay the generation of Weed Resistance.
Nicosulfuron, sulfonylurea herbicide, English name is nicosulfuron, and chemical name is: 2-(4,6-dimethoxypyridin-2-base carbamido group sulphonyl)-N, N-dimethyl nicotinamide.Nicosulfuron is interior absorption, high efficiency corn weed killer herbicide, with effectively preventing and kill off multiple annual gramineous weed in corn field after low dosage bud, also has certain preventive effect to broad leaved weed and sedge weed.It is absorbed rapidly by leaf and root, and is conducted rapidly by xylem and phloem.The synthesis of branched-chain amino acid is stoped by acetolactate synthestase.Use rear weeds to stop growing immediately, 4 ~ 5 days young leaves fade, downright bad, and progressively expand to whole plant, under general condition, process plant death in 20 ~ 25 days.This medicine not only has cauline leaf process effect, also has activity of weeding before bud.Corn has good drug resistance to this medical instrument, occurs temporary transient chlorisis or slight hypoevolutism, but generally can recover rapidly and the not underproduction after process.
Florasulam, English name is florasulam, and chemical name is: the fluoro-5-ethyoxyl of 2', 6'-bis--8-fluorine [1,2,4] triazole [1,5-c] pyrimidine-2-sulfonanilide.Florasulam is triazolopyrimidine sulfonamides inner sucting conduction type super-high-efficient weed killer herbicide, can conduct to weeds complete stool, and thus herbicide is thorough, can not recur.Efficacy stability at low temperatures, even still can ensure stable drug effect 2 DEG C time, this point is that other weed killer herbicides are incomparable.Broad leaved weed is prevented and kill off for corn field.Florasulam broad weed-killing spectrum, the most of broad leaved weed of corn field can be prevented and kill off, comprise the difficult anti-weeds such as kitchen garden, Amaranthus retroflexus, acalypha copperleaf, Siberian cocklebur, field bindweed, field thistle, dayflower, and in corn field the most difficult prevent and kill off lamb's-quarters, piemarker, Siberian cocklebur, black nightshade, field bindweed, field thistle, have extraordinary inhibitory action.
Atrazine, English name is atrazine, and chemical name is: the chloro-4-ethylamino-of 2--6-isopropylamino-1,3,5-triazines.Atrazine is before selectivity inner sucting conduction type seedling, herbicide after seedling, and based on root absorption, cauline leaf absorbs seldom, is transmitted to rapidly plant meristematic tissue and leaf portion, and interference photosynthesis makes weeds lethal.In the resistance crop bodies such as corn, resolved into innocuous substance, thus to safety such as corns by corn ketolase.Its lasting period is longer, broad weed-killing spectrum, prevents and kill off corn field annual weed, mainly better to the preventive effect of corn field broad leaved weed.Atrazine easily by rainwater drip washing to soil comparatively deep layer, also effective to some dark root grass, but easily produce poisoning.When weeds generation density is higher, or when plant is larger, it is difficult to thoroughly kill weeds.When atrazine is used alone, dosage is large, relatively poor to grassy weed effect, has certain influence to second stubble crop wheat and other broad leaf crops.
Nicosulfuron, florasulam and atrazine triple combination, advantage compared with binary combination is: with regard to the binary combination of nicosulfuron and florasulam, after adding atrazine, nicosulfuron and florasulam can be filled a vacancy to the sealing process of Weeds in Spring-maize Field, reduce the new weeds radix that is unearthed, reduce the demutation of weeds, kitchen garden can be solved simultaneously, grass thorough problem waited for death by Siberian cocklebur, field bindweed, field thistle; And add the preventive effect that florasulam is resistance broad leaved weed effect such as wild muskmelon seedling, piemarker, Siberian cocklebur, the black nightshade that can strengthen summer corn and Spring Maize compared with the advantage of nicosulfuron and atrazine binary combination, drug effect can be strengthened in addition and kill deep-rootedness weeds such as field thistle, field bindweed etc.
Applicant finds still do not have the composition patent that nicosulfuron, florasulam and atrazine three are composite at present through retrieval.Find, by nicosulfurons different for the mechanism of action, florasulam and atrazine, to there is obvious synergistic effect through test simultaneously, significantly improve the control efficiency to corn field weed, expand herbicide spectrum, reduce dosage, reduce cost accounting, improve crop safety.
