Abstract
The invention discloses a rice weed killer for weeds in upland rice fields adopting direct seeding in districts of Jiangsu and Zhejiang as well as application thereof. As per the characteristics of the weeds in the upland rice fields adopting the direct seeding in the districts of Jiangsu and Zhejiang as well as local climatic and environmental characteristics, weed killers of quizalofop-p-ethyl, Whip Super emulsifiable concentrate, bensulfuron methyl, fomesafen, sulfonylurea and topramezone, which have different functions and characteristics, are reasonably screened out and compounded, and weed killers with various formulas and ingredients are used in terms of various periods of rice growing. The weed killer is not only favorable in weed removing effect, but also low in toxicity, expands herbicide controlling spectrum, remarkably reduces the use amount of the weed killer, lessens times of weed killer application, and decreases the cost of the weed killer application; moreover, the weed killer is convenient to prepare, can be stored for a long time, and has high practical value.
Description
Technical field
The present invention relates to the herbicide technology of paddy rice, especially relate to a kind of Jiangsu and Zhejiang Provinces area direct-sowing dry weeds in paddy field rice herbicide and application thereof.
Background technology
Along with the variation of planting type, the generation kind of weeds in paddy field changes greatly in recent years, and the situation is tense, directly or indirectly threatening paddy growth.Between direct sowing rice field, ruderal species class is many, quantity is large, and different ecological area and different cultivation method, and weeds in field kind differs greatly.Area, Jiangsu and Zhejiang Provinces is due to the otherness of the environmental factors such as its weather soil and culture technique, weeds in paddy field is mainly grass family, sedge family, composite family, Scrophulariaceae, Alismataceae, Lythraceae etc., and the sociales weeds in direct-sowing dry rice field are barnyard grass, the moleplant seed of growing thickly, wild water chestnut, red rice etc.; And with respect to the rice field of transplanting rice seedling by hand, transplanting, rice transplanting, the direct-sowing dry rice field this rice operation mode weeds extent of injury is higher.Rice herbicide correct using that How to choose is suitable are far-reaching research topics.
Summary of the invention
Goal of the invention: high in order to solve in prior art area, the existing Jiangsu and Zhejiang Provinces direct-sowing dry weeds in paddy field extent of injury, the less problem of weed killer herbicide targetedly, the present invention proposes a kind of a kind of Jiangsu and Zhejiang Provinces area direct-sowing dry weeds in paddy field rice herbicide and application thereof that well also can expand herbicide spectrum to the preventive effect of weeds in field.
Technical scheme: to achieve these objectives, the present invention takes following technical scheme: area, a kind of Jiangsu and Zhejiang Provinces direct-sowing dry weeds in paddy field rice herbicide, the bensulfuron-methyl that the prestige despot missible oil that the Quizalotop-ethyl that the mass fraction that comprises the component of following percentage by weight: 5%-20% is 5%, the mass fraction of 0%-15% are 6.9%, the mass fraction of 0%-15% are 10%, the fomesafen of 0%-20%, the sulfonylurea of 0%-15%, the stupid azoles humulone of 3%-20%, the surfactant of 1%-5%, the dispersant of 1%-5%, water surplus.
Further, described surfactant is arene surfactant.
The application of area, above-mentioned Jiangsu and Zhejiang Provinces direct-sowing dry weeds in paddy field rice herbicide in rice cultivation, is specially the application different growing stage of area, described Jiangsu and Zhejiang Provinces direct-sowing dry weeds in paddy field rice herbicide in rice cultivation specifically different:
(a) before sowing: 3-6d before rice growing, drain rice field internal water accumulation, after the weed killer herbicide of filling a prescription has below been prepared, spray to execute and spill: the bensulfuron-methyl that the Quizalotop-ethyl that the mass fraction of 10%-20% is 5%, the mass fraction of 10%-15% are 10%, the sulfonylurea of 5%-15%, the stupid azoles humulone of 3%-5%, the surfactant of 1%-5%, the dispersant of 1%-5%, water surplus; Sprinkling amount is 20-30kg/ mu;
(b) seeding stage: 3-7d after rice seedling, after the weed killer herbicide of filling a prescription has below been prepared, spray to execute and spill: the bensulfuron-methyl that the prestige despot missible oil that the Quizalotop-ethyl that the mass fraction of 5%-10% is 5%, the mass fraction of 10%-15% are 6.9%, the mass fraction of 5%-10% are 10%, the fomesafen of 15%-20%, the sulfonylurea of 2%-10%, the stupid azoles humulone of 15%-20%, the surfactant of 1%-5%, the dispersant of 1%-5%, water surplus; Sprinkling amount is 30-40kg/ mu;
(c) fertilizer application period: 7-10d after the each fertilising of paddy rice, after the weed killer herbicide of filling a prescription has below been prepared, spray to execute and spill: the sulfonylurea of the Quizalotop-ethyl that the mass fraction of 5%-10% is 5%, the fomesafen of 0%-20%, 0%-5%, the stupid azoles humulone of 10%-20%, the surfactant of 1%-5%, the dispersant of 1%-5%, water surplus; Sprinkling amount is 30-35kg/ mu;
(d) tillering stage: in paddy rice 5-7 leaf tillering stage, after the weed killer herbicide of filling a prescription has below been prepared, spray to execute and spill: the prestige despot missible oil that the Quizalotop-ethyl that the mass fraction of 5%-10% is 5%, the mass fraction of 0%-5% are 6.9%, the fomesafen of 0%-10%, the sulfonylurea of 3%-15%, the stupid azoles humulone of 3%-10%, the surfactant of 1%-5%, the dispersant of 1%-5%, water surplus; Sprinkling amount is 25-35kg/ mu.
Quizalotop-ethyl is to have removed the improvement goods after inactive optical isomer in the process of synthetic quizalofopethyl.Its mechanism of action and herbicide spectrum is similar to quizalofopethyl, absorbs by weeds cauline leaf, and Bidirectional Conduction up and down in plant corpus, is accumulated in top and mitogenetic between two parties, suppresses cell fatty acid and synthesizes, and makes weeds necrosis;
Prestige despot missible oil has good removal effect for moleplant seed;
Bensulfuron-methyl is selectivity inner-adsorption conduction-type herbicide; Active ingredient can spread rapidly in water, absorbed by weeds root and blade the each portion of weeds that transfers to, hinder the biosynthesis of the acid of figured silk fabrics base, leucine, isoleucine, division and the growth of prevention cell, responsive weed growth function is obstructed, tender tissue turns to be yellow too early suppresses the growth of leaf portion, hinders root growth and necrosis.It is harmless inert compound that active ingredient enters rapid metabolism in paddy rice body, to rice safety, has good effect for the removal of wild water chestnut;
Stupid azoles humulone is inner-adsorption conduction-type herbicide, the cauline leaf inorganic agent of high selectivity.Can prevent and kill off annual and perennial grassy weed;
Fomesafen is that one has high selectivity herbicide after seedling, can effectively prevent and kill off soybean, Peanut Fields broad leaved weed and the rhizome of nutgrass flatsedge, and grassy weed is also had to certain preventive effect;
Sulfonylurea all has good removal effect to grass family, sedge weed;
Several materials are used as separately weed killer herbicide all can not reach efficient herbicidal effect to Jiangsu and Zhejiang Provinces area direct-sowing dry weeds in paddy field above, composite through screening, and can reach above object for the use that paddy growth different times carries out different proportioning weed killer herbicides.
Beneficial effect: a kind of Jiangsu and Zhejiang Provinces area direct-sowing dry weeds in paddy field rice herbicide provided by the invention and application thereof, for characteristic and the local climatic environment feature of area, Jiangsu and Zhejiang Provinces direct-sowing dry weeds in paddy field, by Quizalotop-ethyl, prestige despot missible oil, bensulfuron-methyl, fomesafen, it is composite that these several weed killer herbicides with different efficacies and characteristic of sulfonylurea and stupid azoles humulone carry out reasonably screening, and at the different times use different formulations of paddy growth and the weed killer herbicide of proportioning, not only killing except effective weeds, and low toxicity, herbicide spectrum expands, significantly reduce dosage, spraying times and drug cost, and weed killer herbicide preparation is convenient, holding time is long, there is very strong practical value.
