Abstract
An agricultural chemical as a smoking tablet for effective control of vegetable's gray mold is prepared from the mixture of Sukeling and chlorothalonil, combustion adjuvent, ammonium nitrate as oxidant, pottery clay as cooling agent and sulfur as synergist through coarse crushing, mixing, pulverization, press for shaping and packing.
Description
The invention belongs to and contain the bactericide field that postpones or continue to discharge the composition that distributes smog, particularly a kind of smoke agent and production method thereof that contains Sukeling and tpn.
In recent years, China's protection ground growing vegetables area enlarges rapidly, also has the trend that continues development from now on.Because the special ecotope in protection ground helps infecting of disease and popular; so multiple diseases such as gray mold, downy mildew takes place serious day by day and becomes the limiting factor that vegetables are given stable high yields irrespective of drought or water logging; wherein the loss that causes of the gray mold that causes with Botrytis cinerea is generally 20-30%, can reach 50% or more when serious even has no harvest.It is not only domestic important disease, also is a kind of worldwide disease.The chemical control of relevant gray mold is subjected to domestic and international agricultural chemicals circle always and payes attention to.Be that the benzimidazole germicide of representative is succeeded in developing latter stage in the sixties with the carbendazim, once played a significant role to preventing and treating various eliminating vegetable botrytis, but delivered the drug-fast report of this series bactericidal agent after several years both at home and abroad in succession, and genetics of resistance is very stable.Middle nineteen seventies is that the dicarboximide fungicide of representative is succeeded in developing with the Sukeling, has improved the chemical control level of gray mold greatly.This series bactericidal agent not only has high selection toxicity to ash arrhizus bacteria, and prevents, controls anti-and interior suction conduction in addition, therefore generally is subjected to vegetable grower's welcome and becomes the first-selected medicament of preventing and treating gray mold.But because continuous several times is used this class medicament, pathogen has produced pesticide resistance to some extent.For delaying and overcoming resistance; usually protective fungicides such as promotion and mancozeb, tpn are rotated or are used alternatingly; or directly Sukeling and this class medicament to be processed into the wetting powder be the mix preparation of feature, and wetting powder provides advantage because of raising leaf table microclimate relative moisture for pathogen infection.
The object of the invention is to provide clear smoke agent of a kind of grey mold and dry-pressing formed production technology thereof, and this smoke agent can effectively be prevented and treated eliminating vegetable botrytis.
For reaching above-mentioned purpose, the present invention adopts following technical scheme: the clear smoke agent of grey mold, contain parts by weight 10-30 part Sukeling, tpn mixture, 20-50 part combustion adjuvant, 30-60 part oxidant and 3-10 part cooling agent.
The synergist sulphur that also contains 2-10 part.
Sukeling, tpn weight ratio are 1: 1-1: 8, and combustion adjuvant can be wood powder, sawdust, peanut skin or cotton straw; Oxidant can be ammonium nitrate, potassium nitrate; Forming agent can be potter's clay, land plaster, talcum powder, titanium dioxide or starch.
The dry-pressing formed production technology of the clear smoke agent of grey mold comprises following operation successively: material coarse cutting, mixing are pulverized, compression moulding, and material coarse cutting should carry out respectively, and control granularity to the 40-100 order, and compression moulding operation pressure is the 6-20 ton.
Pack fast with plastic sack after the compression moulding.
Sukeling, two kinds of effective ingredients of tpn are mixed use among the present invention, can delay and overcome the pesticide resistance that continuous use Sukeling is produced, and the control eliminating vegetable botrytis is had the notable synergistic effect.Make smoke agent, use simple, and because flying away of soot dust granule improved medicament greatly at the plant surface coverage, also overcome wetting powder and provide the weakness of advantage for pathogen infection because of having improved leaf table microclimate relative moisture, therefore not only can bring into play the prophylaxis effect of bactericide to greatest extent, and can reduce dosage, be easy to welcome, accept into numerous vegetable growers.This smoke agent is mainly used in gray mold, the stalk break of control protection ground vegetables.Can lay according to canopy chamber size during use and put smoke point, the taking-up smoked sheet is directly lighted and is got final product, every mu of each 300-200 gram of using dosage, and dispensing in 7-10 days is once.Dispenser should be carried out between the lights, puts behind the cigarette airtight 12 hours of canopy chamber.
Field test results: the protection ground tomato early flowering season with the clear smoke agent of 15% grey mold; every mu 300-200 gram, continuous dispenser in seven days is three times at interval, and control efficiency is 88.6-81.8%; obviously surpass Sukeling and the agent of tpn list, this medicine to tomato safely, find no any poisoning effect.
Embodiment gets 35 parts in ammonium nitrate, 3 parts in sulphur, and 7 parts in potter's clay is broken into fritter respectively and is respectively charged into the cracker pulverizing again, and smashing fineness is 100% mistake, 40 mesh standard sieves.
Get 12 parts of tpns again, 3 parts of Sukelings, 40 parts of wood powders and above-mentioned composition be all by cracker one time, pulverizes mixed material and enter mixer and fully mix.
Compound enters dry-pressing formed machine and is packing after the extrusion modling under 16 tons of pressure.
Should guard against damp in the production process, gas defence, fire prevention.
