example 1

[0014] Bioassay Example 1: Indoor toxicity assay of crabgrass complexed with allyl isothiocyanate and chloropicrin

[0015] Test object: Crabgrass (Digitaria sanguinalis), collected from the field, selected plump and consistent seeds, and primed for germination.

[0016] Test method: Allyl isothiocyanate and chloropicrin were prepared into 5 series of mass concentrations according to the test ratio, namely 50 μg / mL, 25 μg / mL, 12.5 μg / mL, 6.25 μg / mL, 3.125 μg / mL , and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. Load 600g of field soil into a 2L dryer, add 30mL of the prepared medicinal solution to each dryer, and sow 50 germinated weed seeds. The treatment time was 5 days, and the air was opened for 4 days after the cover was opened, the bud length of each treated weed was measured, and the control effect was calculated.

[0017] The formula for calculating the control effect is:

[0025] Bioassay Example 2: Indoor virulence assay of allyl isothiocyanate and chloropicrin complex against root-knot nematodes

[0026] Test object: Meloidogyne incognita, the soil from which the nematodes occurred over the years was collected for future use.

[0027] Test method: Allyl isothiocyanate and chloropicrin were prepared into 5 series of mass concentrations according to the test ratio, namely 50 μg / mL, 25 μg / mL, 12.5 μg / mL, 6.25 μg / mL, 3.125 μg / mL , and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. 600g of field soil was placed in a 2L desiccator, and 30mL of the prepared medicinal solution was added to each desiccator. The treatment time was 5 days. After opening the cover, the air was opened for 4 days. The number of nematodes in each treatment was determined by centrifugation. control effect.

[0036] Bioassay Example 3: Indoor virulence assay of allyl isothiocyanate and chloropicrin complex against Fusarium

[0037] Test object: watermelon fusarium wilt (Fusarium oxysporum f.sp.niveum.), collect the soil that has suffered from fusarium wilt over the years for use.

[0038] Test method: Allyl isothiocyanate and chloropicrin were prepared into 5 series of mass concentrations according to the test ratio, namely 50 μg / mL, 25 μg / mL, 12.5 μg / mL, 6.25 μg / mL, 3.125 μg / mL , and a single-dose control and a blank control were set at the same time, and each treatment was repeated 3 times. 600g of field soil was placed in a 2L desiccator, and 30mL of the prepared medicinal solution was added to each desiccator. The treatment time was 5 days. After opening the cover, the air was opened for 4 days. The plate dilution method was used to determine the number of Fusarium spp. in each treatment. , calculate the control effect.

Abstract

The invention relates to a synergistic soil fumigation composition, the effective components of which are allyl isothiocyanate (A) and chloropicrin (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 synergistic soil fumigation composition, belonging to the field of plant protection, in particular to a composition compounded by allyl isothiocyanate and chloropicrin. Background technique [0002] Soil-borne diseases, nematode damage 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 are accumulated, they can infect the roots and stems of crops, causing devastating effects on crops. The pathogens are highly resistant to stress and can generally survive in the soil for several years. As long as such diseases have occurred in the fields, they will continue to occur in the future. For the increasingly serious infectious diseases, there is currently no effective therapeutic agent in the market. [0003] Nematodes are also a very harmful type of disease. Some crops are even difficult to gro...
