Embodiment

[0035]The following formulation examples and examples are given to illustrate the present invention, but these are merely examples for illustrating the present invention, and the present invention is not limited to these formulation examples and examples.

preparation example 1

[0037] Fill the weighed 1000g methyl iodide into the high-pressure gas cylinder, then fill with liquefied carbon dioxide gas for dissolving, thereby preparing a fumigant for wood parasitic nematodes whose concentration of methyl iodide in the liquefied carbon dioxide gas is 50% by mass.

Embodiment 1

[0039] Red pine logs parasitized with pine wood nematodes were made into 15cm square timber, 10cm square timber and 2cm×10cm plate, and were cut into 1m lengths respectively. Appropriately place each timber in a tubular frame, stacked to reach 1m 3 volume. Cover the tubular frame with fumigation sheet to make 2.0m 3 volume tent. 160g / m 3 The methyl iodide preparation prepared in formulation example 1 (80g / m in terms of methyl iodide) 3 ) sprayed into the tent for dosing, and fumigated at 15°C for 24 hours. After fumigation, open the tent and place the test wood for 1 week. Nematode investigation was carried out by the Baermann method. The wood in which 10,000 or more pine nematodes were parasitized per 100 g of wood chips in the inspection before the fumigation treatment was used as the object of study. Three pieces of 15cm square, 10cm square, and three planks were tested respectively, and 100g of wood chips were collected from more than 3 positions of each piece of wo...

Abstract

The invention provides a wood parasitic nematode fumigant, which is characterized in that methyl iodide dissolved in liquefied carbon dioxide gas is used instead of destructive matters from an ozonosphere, to use bromomethane limited in the world range; or, the methyl iodide is used together with any, or two or more compound of the sulfuryl fluoride, the methyl isothiocyanate, the phosphine, the ethylene oxide, the carbonyl sulfide and the propylene oxide; the invention also provides a wood fumigating method, which can kill the wood parasitic nematode by using the fumigant.

Description

technical field [0001] The invention relates to a fumigant for wood parasitic nematodes. In more detail, the present invention relates to methyl iodide (CH 3 1) Fumigants and wood fumigation methods for wood parasitic nematodes formed by dissolving in liquefied carbon dioxide gas. Background technique [0002] From the point of view of plant epidemic prevention, agricultural and forestry crops imported into Japan must be inspected, and if necessary, harmful animals and plants must be expelled through fumigation, etc., in order to prevent the invasion and reproduction of harmful animals and plants that do not survive in Japan. For imported wood, from the same point of view, the standards for disinfection methods are also given by the imported wood quarantine clauses, and disinfection must be implemented. As the treatment method of imported wood that has been practically used at present for this purpose, a treatment method using chemical agents such as methyl bromide, a phys...
