Description
Technical field
The invention belongs to soil technical field of pesticide, be specifically related to a kind of DMDS, chloropicrin and AVMComposite soil fumigant and the application in control root-knot nematode and soil-borne disease thereof.
Background technology
Soil disinfection technology be one can kill efficiently, rapidly pathogenetic bacteria in soil, fungi, weeds, nematode withAnd subterranean pest-insect also can suppress the technology of its growth. Along with further expansion and the high added value crop of warmhouse booth cultivated areaCultivation year after year, the problem of soil-borne disease is more and more outstanding, often cause the underproduction reduce product quality. Therefore soil disinfection technologyA kind ofly can effectively control one of important measures of soil-borne disease.
Traditional method of preventing and treating soil-borne disease has breeding for disease resistance, carries out crop rotation, ploughs deeply grafting, uses chemical pesticide etc.Wherein the most frequently used is also that effective method is to carry out soil-fumigating sterilization, and fumigant used mostly is methyl bromide. Methyl bromide soilEarth sterilization can be eliminated nematode in soil, fungi, insect, weeds etc. well, and crop yield is remarkable, is deeply subject to peasant joyous in productionMeet, domestic and international application is extensive. But due to the methyl bromide material that damages the ozone layer, united state classifies United Nations Environment Programme (UNEP) limit control material asTo ban use of in 2015.
Have for the alternative chemicals of Celfume at present multiple, wherein conventional have chloropicrin, 1.3-dichloropropylene,Metham-sodium, dazomet, DMDS, iodomethane etc. But the result of use of single dose is not obvious, and broad spectrum activity is not strong, as DMDSSoil is passed to nematode good effect, but poor to the effect of disease fungus and bacterium, chloropicrin has disease fungus and bacteriumWell effect, but poor to nematode effect. Therefore, suitable soil fumigant is used in combination to expanding prevention spectrum and controlEffect, becomes a significant research topic.
Summary of the invention
The object of the present invention is to provide a kind of DMDS, chloropicrin and abamectin compounded soil fumigant.
The present invention also aims to provide above-mentioned soil fumigant at control soil-borne disease fungal pathogens, in nematode and weedsApplication.

Beneficial effect of the present invention: soil fumigant of the present invention adopts DMDS, chloropicrin and AVM multipleThe composition of joining, can effectively prevent and treat soil-borne disease fungal pathogens, and nematode and weeds, have broad spectrum activity. Composition of the present invention is to rootTie lines worm, reaping hook belongs to fungi, Phytophthora fungi, pythium fungi, beak load belongs to fungi, Colletotrichum fungi, the mould genus of post fruit is trueBacterium, must belong to fungi by shell spore, and silk core belongs to fungi and wheel branch belongs to fungi, and weeds in field all has obvious synergistic effect, use conveniently,To crop safety, meanwhile, it is residual that three kinds of medicaments all do not have in soil, to crop safety.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
Embodiment 1
The reagent that the present embodiment adopts is:
DMDS (DMDS, Shanghai Yuan Ji Chemical Co., Ltd.)
Chloropicrin (Dalian dye chemical industry Co., Ltd)
AVM (Shanghai Yuan Ji Chemical Co., Ltd.)
For examination soil sample be:
Tomato is planted more than 5 years by Guan County, warmhouse booth band pathogen and nematode soil sample. Soil moisture is 18.71%: soilEarth unit weight is 0.86:, the quality of soil is sand grains 81.824%, powder 16.221%, clay 1.955%. Fumigation time is15d, the soil temperature when stifling is 20 DEG C-28 DEG C.
Evaluation index and method are:
Meloidogyne incognita Meloidogyneincognita., adopts centrifugal process;
Fusarium Fusariumspp., adopts Komada method to separate;
Phytophthora Phytophthoraspp., adopts Masago method to separate;
Must belong to Pyrenochaeta by shell spore;
Verticillium dahliae Verticilliumdahliae;
Piemarker Abutilontheophrasti, adopts vernier caliper measurement bud long;
Lady's-grass Digitariasanguinalis, adopts vernier caliper measurement bud long;
Lolium temulentum Loliumtemulentum, adopts vernier caliper measurement bud long;
Artemisiifolia Commenrag-weed, adopts vernier caliper measurement bud long.
Test method
1, dose setting
Press DMDS (active ingredient) and soil quality ratio design concentration for the treatment of 60mg/kg (40g/m2)；
Press chloropicrin (active ingredient) and soil quality ratio design concentration for the treatment of 30mg/kg (20g/m2)；
Press AVM (active ingredient) and soil quality ratio design concentration for the treatment of 1.5mg/kg (1g/m2)；
The each processing of experimental group is as follows:
2, process of the test
Take the ready soil sample of 600g, put into 2.5L drier. Each processing is the program request lady's-grass kind of vernalization respectively20 of sons, 20, piemarker seed, 20, lolium temulentum seed, 20, artemisiifolia seed, then by DMDS, chloropicrin and avermitilis strainElement accurately pipettes with liquid-transfering gun respectively. Stifling 5d at 25 DEG C. Spacious gas 1d after stifling end, then separates nematode and soil-borne disease former trueBacterium, the bud of simultaneously measuring lady's-grass, piemarker, lolium temulentum and artemisiifolia is long. And space management is set, each processing repeats for 3 times.
3, computational methods
Root-knot nematode survival rate and corrected mortality calculate with following formula:
The total borer population of survival rate %=100 × survival nematode number/confession examination
Corrected mortality %=100 × (processing the death rate-contrast death rate)/(1-contrasts the death rate)
Pathogen inhibiting rate calculates with following formula:
Inhibiting rate %=100 × (check plot pathogen quantity-chemicals treatment district pathogen quantity)/check plot pathogen numberAmount
Weeds inhibiting rate calculates with following formula:
Inhibiting rate %=100 × (blank weeds bud length-chemicals treatment weeds bud is long)/blank weeds bud is long
Calculate preventive effect the field efficacy with actual measurement according to Colby method (1966) formula, easy, effectively evaluate mixtureSynergy effect. Computing formula is:
E＝X1×X2...×Xn/100(n-1)
E is the theoretical preventive effect of mixture; N is the quantity of mixed medicament; X1Represent to use the 1st kind of preventive effect after medicament; X2RepresentUse the 2nd kind of preventive effect after medicament medicament; XnRepresent to use the preventive effect after n kind medicament. When the actual preventive effect of mixture is greater than theoryWhen preventive effect, represent synergy; In the time that the actual preventive effect of mixture is less than theoretical preventive effect, represent antagonism.
