preparation example Construction

[0038] The application of shan pepper extract for the preparation of nematicides. The nematicide contains 10% to 30% of the mountain pepper extract by mass. The preparation method of the mountain pepper extract includes: the mountain pepper extract is pulverized and then extracted with an organic solvent to obtain a concentrated solution equivalent to 1kg dry powder / kg; the organic solvent extraction method is ultrasonic extraction, and the extraction temperature is 30° C., the leaching time is 0.5 to 1 hour, and the mass ratio of mountain pepper to the organic solvent is 1: (5 to 10). The particle size of the pulverized pepper fruit is 1-5 mm; the organic solvent is methanol.

[0039] A mountain pepper nematicide, the nematicide is mainly composed of a mountain pepper extract, and the mass percentage of the mountain pepper extract is 10% to 30%.

[0040]The preparation form of the nematicide is an emulsifiable concentrate, and the auxiliaries of the emulsifiable concentrate...

Embodiment 1

[0062] Example 1 Preparation of 20% Mountain Pepper Extract Microemulsion

[0063] Take by weighing 20kg of mountain pepper concentrate, be dissolved in 30kg methanol, add 15kg calcium dodecyl benzene sulfonate, 5kg styrene acid polyoxyethylene ether, 5kg ethylene glycol, mix under high-speed stirring, be heated to 40 ℃ about; add 25kg of deionized water dropwise under high-speed stirring, control the dripping speed of the water, and keep the temperature at about 40°C; after the addition of water dropwise, heat up to 50°C and stir for 1 hour to obtain 100kg of 20% mountain pepper extract microemulsion . The stability and appearance of the preparation meet the requirements of commercial preparations.

Embodiment 2

[0064] Example 2 Preparation of 20% Mountain Pepper Extract Soluble Liquid

[0065] Take by weighing 20kg of mountain pepper concentrate, be dissolved in 30kg methanol, add 15kg sodium dodecyl benzene sulfonate, 4kg ethylene glycol, 0.3kg polyvinyl alcohol under stirring, make up to 100kg with deionized water, after mixing, Stirring at a stirring speed of 800-1000 revolutions per minute for 10-30 minutes, 100 kg of the soluble liquid preparation of the bell pepper extract can be prepared. The stability and appearance of the preparation meet the requirements of commercial preparations.

Abstract

The invention discloses a lindera glauca nematicide and a preparation method and application thereof.The preparation method comprises the steps that lindera glauca fruits are smashed and processed to prepare lindera glauca extract nematicidal soluble liquid, microemulsion and fumigant, and the lindera glauca extract nematicidal soluble liquid, microemulsion and fumigant can be used for preventing and controlling meloidogyne incognita on crops such as tomatoes, pumpkins and cucumbers; white) Chitwood, and can also be used for preventing and treating potato stem nematode Ditylenchus destructor on crops such as potatoes, sweet potatoes and the like, and also can be used for preventing and treating potato stem nematode Ditylenchus destructor. The preparation contains 10-30% of lindera glauca extract and the balance of auxiliaries. The nematicide disclosed by the invention not only has a good nematicidal effect, but also is safe to the environment, people, livestock, natural enemies of pests and other beneficial organisms. The nematicide is simple in preparation process, low in cost and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the field of plants and applications thereof, and in particular relates to a mountain pepper nematicide, a preparation method and applications thereof. Background technique [0002] Meloidogyne incognita (Kofold&White) Chitwood is an important parasitic nematode with a wide host range and can harm hundreds of plants. When the incidence of root-knot nematode is mild, there is no obvious change in the aerial part of the plant, so it is not easy to detect. When the disease is serious, the leaves of the plant turn yellow, wilt, the plant is dwarfed, the fruit yield decreases, the quality decreases, and even the plant dies. The control of root-knot nematodes is very difficult due to the characteristics of adaptability, fecundity, concealment and chemical resistance. According to statistics, plant diseases caused by M. incognita each year will directly or indirectly cause economic losses of about 50 billion in different industries a...
