Abstract
A biochemically synergistic herbicide composition relates to the technical field of agricultural production and comprises effective components, an assistant and a filler, and the effective components comprise Sclerotium rolfsii and quinclorac. The composition adopting Sclerotium rolfsii compounding has a high efficiency and a broad-spectrum weeding effect, has an excellent control effect on many broadleaf weeds and sedges of directly seeded drought rice, and weeds in fields externally invading by weeds, and has a better effect than respective use of Sclerotium rolfsii and quinclorac. The composition has the advantages of safety to crops, low cost and good control effect. Test proves that the herbicide composition has stable chemical properties, high efficiency and broad spectrum, and has an obvious synergistic effect on control objects.
Description
Technical field
The present invention relates to field of agricultural production technologies, particularly the preparing technical field of weed killer herbicide.
Background technology
The economic loss that China causes because of Weed infestation is every year more than hundred billion, and control the means of crop smothering at present owing to not having biological weed killer product, be mainly also the use of dependence 100,000 tons of chemical herbicides, chemical herbicide usable floor area is more than 1,000,000,000 mu.Thus, a large amount of chemical weed control causes the problem such as poisoning and Practice for Pesticide Residue in Agricultural Products of soil and water pollutions, herbicide resistance, crop.Only cause weed killer herbicide usage amount year to increase by 10,000 tons with regard to herbicide resistance, this exacerbates the pressure of environmental pollution, reduces herbicidal effect.It is key element the most key in current various cultivation technique that crop smothering in Rice Production controls.The no water layer of the processes such as live, transplanting covers and dry wet alternating environment is that the outburst of weeds provides condition, can cause the grain drop in production of 50-91% time the most serious.Usually needing use to eliminate for 2 ~ 3 times could basic controlling crop smothering, also often causes serious poisoning due to improper use etc.
The new herbicides of development based on biological weed killer, by biological insect control and chemistry except combining, minimizing chemical herbicide consumption meets sustainable agriculture development direction on the one hand, also fills up the blank of China's product; Poisoning that chemical herbicide causes, pesticide resistance and the problem such as residual can be overcome on the other hand because the high security of biological weed killer, environment friendly, the fast adaptability of microbial inoculum own and lasting period are long etc.
Sclerotium rolfsii for raw material, adopts fungi fermentation technology, straw decomposing technology etc. with agricultural byproducts such as agricultural crop straws, has weeding, applies fertilizer, returns crop stocks to the field, identifies and prevent and kill off exotic invasive weed, improve the effects such as soil property.Be applied to agricultural plant chemoproection field, the multiple broad leaved weed of direct-sowing dry paddy rice, nutgrass flatsedge and the weed control by Alien Weeds invasion ground can be widely used in, and to gramineous crop and turfgrass safety.
Dichloro quinolinic acid is the special efficacy selective herbicide of control barnyard grass in paddy field, remarkably productive to 4 ~ 7 leaf phase barnyard grasses.Selectivity is strong, and the amplitude broad in dispenser period, a dispenser can control the barnyard grass of whole growth period duration of rice.Effectively can also prevent and kill off Monochoria vaginalis, Chinese celery etc.Poor to the control efficiency of sedge weed.This compound can be absorbed by seed, root and the leaf portion of sprouting, and has the feature of hormone herbicide, similar to the effect symptom of auxin substance.The detailed mode of action in plant corpus is still among research.There is slight chlorosis phenomenon in barnyard grass of being injured tender leaf, blade occurs longitudinal stripe and bends.After sandwich barnyard grass is injured, leaf chlorosis becomes puce to withered; Active ingredient can be decomposed, thus to rice safety by the root of paddy rice.This compound has larger mobility in soil, can be decomposed by edaphon.
Summary of the invention
The object of the invention is the multiple weak point existed for current wide spectrum, efficiency biological weed control agent shortage and existing chemical herbicide, providing a kind of is formulation with granule, has herbicidal composition that is efficient, broad spectrum weeding function simultaneously.
The present invention is made up of active ingredient and auxiliary agent, filler, and active ingredient is made up of Sclerotium rolfsii and dichloro quinolinic acid.
Described Sclerotium rolfsii accounts for 1 ~ 40% of herbicidal composition gross mass, and dichloro quinolinic acid accounts for 1 ~ 30% of herbicidal composition gross mass.
The present invention adopts Sclerotium rolfsii composite, there is efficient, broad spectrum weeding function, excellent preventive effect is shown to the multiple broad leaved weed of direct-sowing dry paddy rice, nutgrass flatsedge and the weed control by Alien Weeds invasion ground, exceedes the use of Sclerotium rolfsii and dichloro quinolinic acid two single dose kinds.To crop safety, cost is low, preventive effect good.Proving after tested, herbicidal composition stable chemical nature of the present invention, high-efficiency broad spectrum, revealing obvious synergistic effect to preventing and kill off Object table.
Advantage of the present invention: Sclerotium rolfsii and these two kinds of combination of active principles of dichloro quinolinic acid use, and have both played the biological weed control performance of new bio weed killer herbicide Sclerotium rolfsii, and have embodied again the quick-acting of chemical herbicide dichloro quinolinic acid, improve herbicidal effect.Therefore Sclerotium rolfsii and dichloroquinoline acid composition to the multiple broad leaved weed of direct-sowing dry paddy rice, that nutgrass flatsedge prevents and kill off reached synergistic effect is the most remarkable.Secondly use cost reduces, current Sclerotium rolfsii and dichloro quinolinic acid single dose use cost higher, it is not again fine that low dosage is used alone effect, and therefore Sclerotium rolfsii and dichloro quinolinic acid combinationally use and both improved preventive effect, again reduce agriculture this.
The formulation of product of the present invention is water dispersible granules.
Described auxiliary agent accounts for 2 ~ 25% of herbicidal composition gross mass, and filler accounts for 5 ~ 96% of herbicidal composition gross mass.
Described auxiliary agent by account for respectively herbicidal composition gross mass 0.5 ~ 10% dispersant, the wetting agent of 0.5 ~ 5%, the adhesive of 0.5 ~ 5%, 0.5 ~ 5% disintegrant composition.
Dispersant can adopt the one of lignosulfonates, NNO or any two kinds of mixtures.Wherein, lignosulfonates select calcium lignosulfonate or sodium lignin sulfonate; Wetting agent adopts sodium alkyl benzene sulfonate or alkyl benzene calcium sulfonate; Adhesive adopts soluble starch or polyethylene glycol; Disintegrant adopts amine sulfate or urea etc.Filler adopts kaolin, precipitated calcium carbonate etc.
