Embodiment 1

[0015] The distribution ratio of each component in the oligosaccharide-containing nematicide composition 100g of the present embodiment is respectively:

[0016] Oligochitosan 5g

[0017] Abamectin 0.9g

[0018] Emamectin benzoate 0.5g

[0019] N,N-Dimethylformamide 3g

[0020] Xylene 3g

[0021] Emulsifier 1602 5g

[0022] The balance is water

[0023] Put the above materials into a 200ml beaker and stir to fully dissolve various ingredients, mix evenly, and pack separately. When using this product, add water to dilute this product 1000 times before or during crop planting and mix it with soil or root irrigation.

[0024] The oligosaccharide-containing nematicide of the present invention was tested on cucumbers, and the nematicide Tuxiansan commonly used in the market was used as a control, and there was also a blank control, a total of 3 treatments, 3 repetitions, random arrangement, in Treat the soil before planting. From the four indicators of plant height, number ...

Embodiment 2

[0029] The distribution ratio of each component in the oligosaccharide-containing nematicide composition 100g of the present embodiment is respectively:

[0030] Sodium Alginate Oligosaccharides 5g

[0031] Abamectin 0.9g

[0032] Xylene 3g

[0033] The balance is water

[0034] The oligosaccharides and sodium alginate were dissolved in water in equal proportions respectively, and then the oligosaccharide solution dissolved with abamectin was slowly dropped into the sodium alginate solution to prepare microcapsules. When using this product, mix with the soil and apply 2-5kg / mu.

[0035] The oligosaccharide-containing nematicide of the present invention was tested on cucumber. The commonly used nematicide Tuxiansan in the market was used as a control, and there was also a blank control, a total of 3 treatments, 3 replicates, arranged randomly, and the soil was treated before planting. From the four indicators of plant height, number of leaves, number of roots, and root-kno...

Embodiment 3

[0040] The ratio of each component in the oligosaccharide-containing nematicide composition 100g of the present embodiment is respectively:

[0041] Oligochitosan 5g

[0042] Abamectin 0.9g

[0043] Sodium Alginate Oligosaccharides 5g

[0044] Xylene 3g

[0045] The balance is water

[0046] The oligosaccharides and sodium alginate were dissolved in water in equal proportions respectively, and then the oligosaccharide solution dissolved with abamectin was slowly dropped into the sodium alginate solution to prepare microcapsules. When using this product, mix with the soil and apply 2-5kg / mu.

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. ...
