Abstract
The invention discloses a moisture-holding sustained-release seed treating agent for controlling wheat sharp eyespot. The treating agent comprises components in parts by weight as follows: 2.5-3.3 parts of difenoconazole, 9-12 parts of a moisture-holding agent, 10-13 parts of wetting dispersants, 4-6 parts of a film-forming agent, 1-2 parts of dye, 3-5 parts of a sinking agent and 63.7-65.5 parts of a carrier, wherein the difenoconazole is a 95% raw drug, the moisture-holding agent is in the polyacrylamide type, the wetting dispersants are an emulsifier OP-10 and an NNO (naphthalenesulfonic acid/formaldehyde condensation product), the film-forming agent is polyvinyl alcohol 1788, the dye is carmine, the sinking agent is a mixture of argil and xanthan gum in the mass ratio of 3:1, and the carrier is white carbon black. The moisture-holding sustained-release seed coating has the characteristics of good film-forming property, evenness in coating, low toxicity and environment friendliness and can increase the emergence rate of wheat significantly, prolong the lasting period of the agent and increase the utilization rate of soil moisture and the yield of the wheat.
Description
Technical field
The present invention relates to a kind of water-holding slow-release seed treatment preventing and treating wheat sharp eyespot, belong to agricultural technology field.
Background technology
Wheat sharp eyespot is also known as wheat point eye spot disease, and a kind of silborne fungal diseases mainly caused by Rhizoctonia cerealis (Rhizoctonia cerealis), in the world, all there is generation in each Major Wheat producing region to this disease.Since 20 century 70s, along with the replacing of wheat breed and the popularization of High yield Cultivating Technique (as early sowing, dense planting, high fertilizer etc.), this disease generally occurs in China Winter Wheat Area, and becomes one of Major Diseases of Huang-Huai-Hai plain and Yangtze river basin Mai Qu.Meanwhile, due to increasing of China's machinery cross-regional operation in recent years, wheat sharp eyespot is northward extension gradually, and harm is day by day serious, causes extremely important impact to yield and quality of wheat.At present, the main triazole type dressing seed that adopts prevents and treats wheat sharp eyespot, but usually effectively can not control the onset peak of wheat during jointing stage banded sclerotial blight, still needs to carry out the control of spray medicine; And also easily there is poisoning or emerge to wheat and grow producing inhibitory action in this series bactericidal agent improper use.
Sustained-release pesticides is normally carrier with macromolecular compound.Chemical pesticide, by mode that is direct or that combine with macromolecular compound by crosslinking agent, reaches slow release effect in field.Water-loss reducer (SAP) is the high molecular polymer of a kind of superelevation water-absorbing-retaining ability utilizing strong absorptive resin to make, and according to crop water feature, can provide moisture for a long time after water suction.The present invention is directed to the occurrence characteristic of wheat sharp eyespot, the conventional medicament Difenoconazole of control wheat sharp eyespot is combined with water-loss reducer, obtained a kind of seed treatment, this medicament utilizes the feature of water-loss reducer water-absorbing-retaining, both the object of Difenoconazole slow release long-acting had been reached, extend the prevention and control time to wheat sharp eyespot, the invalid evaporation of water consumpation can be reduced again, improve soil to the savings ability of moisture.
Summary of the invention
The object of this invention is to provide a kind of water-holding slow-release seed treatment of applicable control wheat sharp eyespot, this slowly-releasing seed treatment has the feature of water conservation and slow-releasing agent.
The present invention is achieved through the following technical solutions water-holding slow-release seed treatment, and it comprises following raw material: Difenoconazole 2.5 ~ 3.3 parts, water-loss reducer 9 ~ 12 parts, wetting dispersing agent 10 ~ 13 parts, film forming agent 4 ~ 6 parts, dyestuff 1 ~ 2 part, sagging inhibitor 3 ~ 5 parts, 63.7 ~ 65.5 parts, carrier; Described Difenoconazole is 95% former medicine, water-loss reducer is polyacrylamide, wetting dispersing agent is the mixture of emulsifier op-10 and naphthalenesulfonate formaldehyde condensation compound NNO, film forming agent is polyvinyl alcohol 1788, dyestuff is carmine, sagging inhibitor is the mixture (mass ratio 3:1) of carclazyte and xanthans, and carrier is white carbon.
Wherein said water-loss reducer is polyacrylamide, it is the impact of the index such as Water Retaining Agent on Soil Topsoil water change in time and space and Agronomic Characters in Wheat by studying 6 kinds of different manufacturers, different size, filter out water retention property good, and the water-loss reducer of wheat yield can be significantly improved.
Using method is first water-holding slow-release seed treatment is diluted with water to the dispersion that concentration is the water conservation of 1% ~ 2%, carries out dressing coating to wheat seed, makes water-retaining agent colloid and seed mixing, dries, make to disperse adhesion each other between seed.
Water-holding slow-release seed treatment of the present invention, its feature is can slow-releasing agent, does not affect emergence rate, both can play the effect of pesticide slow-release, can improve again field topsoil water-holding capacity, improves water use efficiency.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail.
Embodiment 1:
Each component and the parts by weight thereof of wheat water-holding slow-release seed treatment are respectively:
As above the fabrication processing of the wheat water-holding slow-release seed treatment of proportioning is:
After adopting LD-200 type high-speed multifunctional cracker to carry out preliminary co-grinding to components such as medicament, wetting dispersing agent, carrier and water-loss reducers, then draw the pulverizing of the formula cracker degree of depth with gas, obtained particle diameter is 10 μm, the seed treatment of 2.5% Difenoconazole.
Embodiment 2:
Each component and the parts by weight thereof of wheat water-holding slow-release seed treatment are respectively:
Its fabrication processing, with embodiment 1, is mixed with the seed treatment containing 3% Difenoconazole.
Embodiment 3:
Each component and the parts by weight thereof of wheat water-holding slow-release seed treatment are respectively:
Its fabrication processing, with embodiment 1, is mixed with the seed treatment containing 3.3% Difenoconazole.
Each embodiment was all implemented in 2012 ~ 2013 years in Agricultural University Of Hebei's test garden.Known through seedlings investigation: compared with contrasting with clear water, be used alone the growth that the process of contrast medicament Difenoconazole obviously inhibits wheat, postponed wheat seedling-growing time, emergence rate also decreases; And compare apparently higher than clear water contrast with the emergence rate of the Difenoconazole seed treatment Cotton seeds wheat of same concentration effective dose, and compared with independent Difenoconazole process, average plant height improves 0.99 ~ 1.99cm, fresh weight increases by 0.06 ~ 0.07g.
Wheat heading stage investigation finds, the water-holding slow-release seed treatment preventive effect of Difenoconazole on average improves 10% ~ 20% than the Difenoconazole process being used alone same concentration effective dose, and the lasting period extends about more than one month.And when using water-holding slow-release seed treatment dressing, thousand grain weight of wheat all significantly increases, and mature spike number and grain number per spike also increase to some extent.It is 18.5% that the independent Difenoconazole seed treatment of contrast medicament comparatively contrasts rate of growth.And the average effect of increasing production of each water-holding slow-release seed treatment Cotton seeds is respectively 24.5%, 26.5%, 19.5%, the independent Difenoconazole Cotton seeds of average specific contrast medicament improves 5%.
