Embodiment Construction

[0019] A carbon disulfide fumigation insecticide, various fumigation insecticides, bactericides, and plant nematodes described in the technical scheme, inert gas carbon dioxide and nitrogen are combined to form various compounding agents. Taking a 10kg sample as an example, each component is weighed on an electronic scale, and the examples are as follows:

[0020] 1 Materials and methods

[0021] 1.1 Materials

[0022] 1.1.1 Diseased wood material

[0023] Black pine (Pinusthunbergii) logs naturally infected with pine wood nematode (B.xylophilus) were collected from Yichang City, Hubei Province, and were peeled and processed into wood segments with a cross-section of 5 cm×5 cm. Put it into a plastic bag and seal it, so that the moisture content reaches a basic balance, and put it under the fumigation temperature condition to balance for 3 days before fumigation.

[0024] 1.1.2 Fumigants

[0025] High-pressure carbon oxysulfide (COS) was purchased from Tianjin Dongxiang Spe...

Abstract

The invention relates to a mixed fumigant and a method for fumigating and killing pine xylophilus. The mixed fumigant consists of the following components in parts by weight: 10-100 parts of carbon oxysulfide, and 1-100 parts of sulfuryl fluoride. The mixed fumigants described above are applied to plant pests and / or their habitat. One-time effective fumigation can be used to treat pests, pathogens, plant nematodes, mites, slugs, etc. The invention is applied to plant quarantine, log, container, soil, scrap steel ship, commodity maintenance, herbarium of animals and plants, grain storage, etc. for fumigation and detoxification treatment, and has great social and economic benefits.

Description

technical field [0001] The invention belongs to the field of pest control, and more specifically relates to a mixed fumigant and a method for fumigating and killing pine wood nematodes. Background technique [0002] With the rapid development of my country's reform and opening up, domestic and international trade has grown rapidly, and the types and quantities of commodities have become more complex and diverse. The probability of spreading harmful organisms such as plant dangerous diseases, insects, nematodes has also increased accordingly, and the time for quarantine release is getting shorter and shorter, and due to the limitation of the type and performance of fumigants, one fumigant cannot comprehensively and effectively deal with pests, nematodes and other harmful organisms. Biological, to ensure the quarantine effect. Repeated treatment prolongs the quarantine release time and increases the cost of fumigation treatment. [0003] Known as the "cancer" of pine trees, ...
