Technical Field

The invention relates to a nematicide taking turpentine as a carrier and application thereof.

Background

Plant pathogenic nematodes cause serious damage to crops and forest resources in our country. Such as root-knot nematodes (Meloidogyne spp.), cyst nematodes (Heterodera spp.), Aphelenchoides besseyi and the like, cause crop yield reduction, are serious in harm and are extremely difficult to control. In forestry, Pine wilting disease (Pine wilting disease) is a devastating disaster caused by infestation of Pine trees by vector insects carrying Pine wood nematodes (Bursaphelenchus xylophilus). Pine wood nematodes are listed as key quarantine objects at home and abroad, once the disease occurs, the disease is difficult to be restrained, and the survival range is expanded and gradually moves to the north, so that the pine wood resources in China are greatly damaged, and serious economic loss and immeasurable indirect loss are generated.

At present, chemical control is still an effective measure for controlling plant pathogenic nematodes, but safety, environmental and health problems caused by the use of pesticides are not negligible, and people need to try to reduce the pollution to the environment on the premise of having to perform chemical control. At present, most of solvents used for dissolving pesticides are organic solvents, and the organic solvents have toxic and harmful effects on plants and human health and have long-term potential safety hazards due to the fact that the organic solvents are difficult to degrade.

Although relatively safe aqueous preparations have been developed, the advantages of stable preparations and good drug action of emulsifiable concentrates have not been ignored. In addition, in the process of controlling the pine wood nematodes, water is mostly adopted as a solvent for dilution when a plurality of nematocides are prepared into working solution, so that the nematocides cannot be well dissolved with turpentine, and cannot be transported and conducted in pine bodies sufficiently. The drug can not fully contact the pine wood nematodes parasitizing in the resin tract of the pine, so that the drug effect can not be fully exerted, and the development of the disease in the forest can not be controlled. Therefore, the problem can be further solved by developing a green substitute which can be dissolved with rosin and is a light aromatic solvent, so that the pathogenic nematodes of the agricultural and forestry plants represented by the pine wood nematodes can be better prevented and controlled.

Disclosure of Invention

The invention aims to solve the problems that most of solvents used for dissolving pesticides are organic solvents which are difficult to degrade and are toxic to plants and human health, and the existing nematicide liquid medicine cannot be well dissolved with turpentine and then cannot be transported and conducted in pine bodies sufficiently so that the pesticide effect cannot be exerted sufficiently, and provides a nematicide taking turpentine as a carrier and application thereof.

The invention relates to a nematicide taking turpentine as a carrier, which consists of 0.1-85% of nematicide, 0.1-20% of cosolvent, 0.1-35% of emulsifier and the balance of turpentine according to mass fraction.

The invention relates to a nematicide taking turpentine as a carrier, which is applied to the prevention and treatment of plant pathogenic nematodes.

The turpentine oil as solvent can stabilize drug effect, and has good stabilizing effect on ultraviolet resistance, strong sunlight resistance, and cold and hot storage of preparation. In addition, the turpentine is a terpene compound, is related to pine resistance, has a repellent effect and has good lipid solubility. The high content of alpha pinene and beta pinene in the turpentine oil is more helpful for pine trees to resist the infection of pine wood nematodes. In the application process of the nematicide taking turpentine as a carrier, turpentine solutions (0.1-99.9%) with different contents are selected to dilute original drugs according to the parasitic habits of different pathogenic nematodes. The method can solve the problem that the nematicide liquid medicine is difficult to dissolve with turpentine, and ensure that the nematicide is fully transported and dispersed in the pine body. Therefore, the application of the nematicide taking turpentine as a carrier not only has no toxic action on pine trees, but also solves the problems that pesticides are difficult to fully dissolve, transport and disperse in the turpentine on the premise of reducing pollution, ensures that the pesticides are fully dissolved, and fully exerts the pesticide effect.
