[0015] Biological Assay Example 1: Indoor Toxicity Determination of Crabgrass by Allyl Isothiocyanate and Dimethyl Disulfide Complex

[0016] Test object: crabgrass (Digitarias anguinalis (L.) Scop), collected from the field, select plump and consistent seeds, and germinate them for later use.

[0017] Test method: prepare allyl isothiocyanate and dimethyl disulfide into 5 series of mass concentrations according to the test ratio, namely 50μg / mL, 25μg / mL, 12.5μg / mL, 6.25μg / mL, 3.125μg / mL, and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. Put 600g of field soil in a 2L desiccator, add 30mL of the prepared medicinal solution into each desiccator, and sow 50 weed seeds that are germinated. The treatment time was 5 days, and the air was opened for 4 days after opening the cover, and the bud length of each treated weed was measured to calculate the control effect.

[0026] Bioassay Example 2: Indoor Toxicity Determination of Root-knot Nematode Compound Allyl Isothiocyanate and Dimethyl Disulfide

[0027] Test object: root-knot nematode (Meloidogyneincognita), the soil where nematode occurred over the years was collected for future use.

[0028] Test method: prepare allyl isothiocyanate and dimethyl disulfide into 5 series of mass concentrations according to the test ratio, namely 50μg / mL, 25μg / mL, 12.5μg / mL, 6.25μg / mL, 3.125μg / mL, and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. Put 600g of field soil into 2L desiccators, add 30mL of the prepared medicinal solution into each desiccator, and the treatment time is 5 days, open the air for 4 days after opening the cover, use centrifugation to measure the number of nematodes in each treatment, and calculate Control effect.

[0038] Test object: Watermelon Fusarium wilt (Fusariumoxysporumf.sp.niveum.), the soil where Fusarium oxysporum f.sp.niveum. occurred over the years was collected for future use.

[0039] Test method: prepare allyl isothiocyanate and dimethyl disulfide into 5 series of mass concentrations according to the test ratio, namely 50μg / mL, 25μg / mL, 12.5μg / mL, 6.25μg / mL, 3.125μg / mL, and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. Put 600g of field soil in 2L desiccators, add 30mL of prepared medicinal solution into each desiccator, and treat for 5 days, open the air for 4 days after opening the cover, and measure the number of Fusarium in each treatment by plate dilution method , to calculate the control effect.

Abstract

The invention relates to a composition for soil fumigation, the effective components of which are allyl isothiocyanate (A) and dimethyl disulfide (B) in a mass ratio of 1:1-1:100. The composition provided by the invention is used for soil fumigation of melons and vegetables, medicinal materials, strawberries, tobacco, fruit trees, and nurseries.

Description

technical field [0001] The invention relates to a composition for soil fumigation, belonging to the field of plant protection, in particular to a composition compounded by allyl isothiocyanate and dimethyl disulfide. Background technique [0002] Soil-borne diseases, nematode hazards and continuous cropping obstacles have become the key factors restricting modern agriculture. The pathogens of soil-borne diseases are parasitic in the soil. Once enough pathogenic bacteria accumulate, they can infect the roots and stems of crops, causing devastating effects on crops. The pathogens have strong stress resistance and can generally remain in the soil for several years. As long as such diseases have occurred in the field, they will continue to occur in the future. For the increasingly serious infectious diseases, there is no effective therapeutic agent in the market yet. [0003] Nematodes are also a very harmful type of disease. Some crops are even difficult to grow and produce b...
