Description
Technical field
The present invention relates to the novel form of a kind of disinfectant use in agriculture of pesticide field, specifically polyoxin water dispersible granules, its preparation method and application.
Technical background
The occupation mode of tradition agricultural chemicals is mainly missible oil and pulvis.The level of the productive forces is not, in very high situation, in order to prevent damage by disease and insect, to capture agricultural foison in the past, and this occupation mode ensures that people's lives have played irreplaceable effect.But; along with the raising of living standards of the people; to the quality requirements of agricultural product also corresponding raising; and international community requires also corresponding raising to the cry of ecological environmental protection and implementation sustainable development; by contrast; the application drawback of missible oil and pulvis is also apparent, and slowly changes to green pesticide form.
Water dispersible granules is a kind of novel formulation, and domestic and international R&D institution, enterprise relatively paid close attention to the research of this formulation in recent years.Water dispersible granules is to use from natural world or synthetic filler to add suitable auxiliary agent, forms through special process granulation, has avoided pulvis to cause in process of production the drift of dust, and environment and operator are worked the mischief.Water dispersible granules is easy to use, and to the mankind and Environmental security, is easy to control release and directed.Water dispersible granules is convenient to packing, metering, transportation and is stored simultaneously, and the residual quantity of packing material is less, so water dispersible granules is a kind of optimal selection that substitutes traditional missible oil and pulvis.
It is the metabolite that streptomyces aureus produces that polyoxin belongs to, and belongs to broad-spectrum antibiotics series bactericidal agent, has the interior conduction of inhaling preferably.Its mechanism of action is to disturb the chitinous biosynthesis of germ cell wall, makes somatic cells wall can not carry out biosynthesis and causes germ death.After germ tube contacts medicament with mycelia, cell inclusion is expanded, breaks, overflowed in part, and can not normal development, causes death.Also there is the effect that suppresses germ product spore and scab expansion.Stable in neutral and weakly acidic solution, in alkaline medium, easily decompose inactivation.

The present invention relates to the former medicine of polyoxin produces voluntarily content by our company and reaches more than 75%, company to polyoxin produce bacterium streptomyces aureus through plasma inject, the method such as genetic engineering modified further improved it and produced plain ability, by the improvement to polyoxin B purifying technique, be further purified B constituent content, the former medicine of 75% above content can be produced, the needs of formulation can be met.
Water dispersible granules in the present invention is to grow up on the basis of wetting powder and suspending agent, this formulation has overcome the shortcoming of suspending agent and wetting powder, have both the advantage that environmental protection and use cost are low, in processing and use procedure, reduce the pollution to environment, and reduced peasant's use cost.The present invention has developed using mineral substance, plant or has contained earthfill rockfill concrete riprap RCC material as carrier, adds auxiliary agent etc., and making it granulating and forming is water dispersible granules.This water dispersible granules can rapid disintegration disperse to form suspension in water.Overcome that wettable powder agent content is lower, filler is more, suspending agent easily lumps and is unfavorable for the shortcomings such as transportation.
Be compared with the prior art, advantage of the present invention and good effect are as follows.
1, neither need with organic solvent, there is no again dust drift, can not burn, can not explode, can save petroleum resources and alleviate environmental pollution, produce and use procedure in to operator and Environmental security.
2, the preparation of high-load be can be processed into as required, packing, storage, cost of transportation saved.
3, physics, stable chemical nature, is difficult for decomposing rotten.
4, finished product is granular solids, good fluidity, and sticky wall after toppling over, can not remain in formation secondary pollution in packing container.
5, available papery packing, is convenient to reclaim and destroys or natural degradation.
6, it is superfine that powder is disperseed rear diameter, is conducive to target and fully absorbs and play a role, and can reduce effective ingredient consumption, improves effect.
7, in the present invention owing to having added the auxiliary agent of heterogeneity, make the present invention there is active component content high, environmental pollution is little, disintegration rate is fast, the good and hot storage of dispersive property steady performance, drug effect is high, safety is good.

Embodiment 6 50% polyoxin water dispersible granules are to cladosporium leaf and fruit mould of tomato control test
Controlling object: cladosporium leaf and fruit mould of tomato, cause of disease is Fulvia fulva(Cooke) Cif., belonging to Deuteromycotina Fulvia fulva belongs to, different name is yellow cladosporium Cladosporium fulvumCooke, and main harm blade also endangers stem, flower and fruit when serious, blade morbidity, initial stage there is yellow green, the unconspicuous spot in edge in face of blade, and the mould layer of canescence appears in leaf back, and rear mould layer becomes light brown to dark brown; When high humidity, blade surface scab also can grow mould layer.Disease is often first fallen ill by lower blade, and gradually to vertical spread, the mould layer when serious of falling ill is covered with blade back, leaf rolling, and it is withered that whole strain blade is yellowish-brown.Tender stem with on carpopodium, also can produce similar scab, floral organ morbidity easily comes off.Fruit morbidity, forms black circle or irregular patch near base of fruit or on fruit face, and sclerosis depression, can not eat.
Experimental field be selected in Cui Gongdi village, Anxin County, Baoding, Hebei province, the tomato variety of planting is that heavenly steed starts 54,2013 year August 23, and medication three times, is respectively August 23, August 31 and September 7, every minor tick 7 days.
Reagent agent 10% polyoxin wetting powder, 50% polyoxin water dispersible granules (sample of embodiment 3), clear water contrast.
For trying multiple: be all diluted to 150ppm according to content and compare.
Investigation content and statistical method: the sick level of investigation blade before the 1st spray medicine, make a record, before spraying medicine, investigate sick grade after 1 spray medicine later at every turn, examine or check medicament to testing the safety of crop, the situation that affects on experiment plant growth, leaf look after visual observations dispenser.Calculate disease index and actual control efficiency.
Severity Scaling standard is:
1 grade: blade is without scab
2 grades: fragmentary little scab appears in blade
3 grades: lesion area accounts for 1/6～1/4 of Ye Erji
4 grades: lesion area accounts for leaf and amasss 1/4～1/2
5 grades: lesion area accounts for leaf and amasss more than 1/2 or cause fallen leaves
Drug effect is calculated
50% polyoxin water dispersible granules is prevented and treated cladosporium leaf and fruit mould of tomato control efficiency (table one)
There is not precipitation or block the phenomenons such as spray holes occurring in 50% polyoxin water dispersible granules in use in use, after 10% polyoxin wetting powder in use repeatedly blocks spray holes and is finished, in sprayer chamber, there is a large amount of fillers and serious wall sticking phenomenon, affect result of use.
In drug effect control, in same 150PPm situation, 50% polyoxin water dispersible granules control efficiency is better than 10% wetting powder, embodies in use many superiority.
