Abstract

The invention discloses a nematicide composition containing oligosaccharides and application thereof. The composition contains a controlling-effective amount of oligosaccharides and nematicide; the content of the oligosaccharides accounts for 1 to 10% of the gross weight of the composition, and the oligosaccharides comprise chitosan oligosaccharide, sodium alginate oligosaccharide and pectin oligosaccharide; and the content of the nematicide accounts for 0.5 to 30% of the gross weight of the composition, and the nematicide is one or more selected from the group consisting of avermectin, carbosulfan, emamectin benzoate, methomyl, chlopyrifos, trichlorfon, lambda-cyhalothrin and phoxim. The composition is applied to field crops, commercial crops and fruits and vegetables suffering from damage by nematode and can effectively prevent occurrence of nematode; as the oligosaccharides capable of inducting disease resistance of plants and promoting root growth are introduced into a nematode controlling drug, growth and nutrient absorption of plants are promoted and a controlling effect is exerted on soil-borne diseases while nematode is killed.

Description

technical field

[0001] The invention relates to the field of agriculture, more specifically to an oligosaccharide-containing nematicide composition and the application of the composition to field crops, economic crops, and fruit and vegetable crops that are harmed by nematodes. Background technique

[0002] Nematodes are one of the major factors affecting the production of melons, vegetables, bananas, etc. In addition to directly causing more than 20% yield reduction, the combined infection caused by nematodes and other pathogens such as Fusarium wilt will also aggravate other soils such as banana Panama disease. The hazards of infectious diseases, resulting in greater economic losses. The current nematode control agents on the market, such as Fufuduo, Haoniandong, etc., are mostly imported from abroad, and are mainly highly toxic and high-residue organophosphorus and carbamate products. Due to environmental and food safety issues Has been banned in more and more regions. ...
