The invention relates to the technical field of edible mushroom planting, and discloses a pleurotus geesteranus culture medium and a preparation method and a culture method thereof, and the pleurotus geesteranus culture medium is prepared from the following raw materials in parts by weight: 60-80 parts of caragana microphylla, 20-40 parts of cottonseed hull, 1-5 parts of lime powder, 6-12 parts of celastrus angulatus rhizome, 3-9 parts of fennel, 10-17 parts of orange peel and 15-20 parts of corncob. Celastrus angulatus rhizome, fennel and orange peel are added into the pleurotus geesteranus culture medium and are all botanical insecticides, insect pests can be effectively prevented and controlled, the yield is increased, and pleurotus geesteranus sporocarp cannot be affected. The celastrus angulatus rhizome has a killing effect on pests in the growth process of pleurotus geesteranus and is a botanical insecticide and a sterilizing agent; anisaldehyde rich in fennel is also an agricultural insecticide; the orange peel has a prevention and treatment effect on springtails.

The invention relates to the technical field of insecticides, in particular to an insecticide composition and a preparation method and application thereof.The insecticide composition is prepared from, by weight, 5-25 parts of neonicotinoid insecticides, 2-15 parts of 4-trifluoromethyl nicotinamide, 2-5 parts of microbial insecticides, 2-20 parts of botanical insecticides and 2-10 parts of sulfonated modified graphene nano powder. 5-15 parts of silicon dioxide-titanium oxide composite powder particles; the microbial insecticide is prepared from bacillus thuringiensis and metarhizium anisopliae; the botanical insecticide is prepared from azadirachtin, veratrine and celastrus angulatus. By matching and combining the raw materials, the prepared insecticide composition can improve the insecticidal effect while reducing the use of neonicotinoid insecticides, and reduces the influence on the farmland environment.

The invention belongs to the field of pesticide preparations, and particularly relates to a celastrus angulatus smoke agent and application thereof. The Celastrus angulatus fuel comprises the following components in percentage by weight: 0.1-2% of Celastrus angulatus, 20-45% of fuel, 5-25% of an oxygen supply agent, 5-15% of a smoke agent, 0.5-2% of a binder and the balance of a flame retardant, the fuel consists of lactose, pulverized coal and saw dust; the oxygen supply agent is composed of ammonium nitrate and potassium chlorate; the smoke agent is composed of ammonium chloride and ammonium bicarbonate; the prepared smoke agent has excellent smoke forming rate and pest control effect, and the dosage of the preparation can be effectively reduced.

The invention provides a medicament for preventing and controlling macadamia nut dichocrocis punctiferalis and a prevention and control method thereof. The medicament is prepared from an antibacterial traditional Chinese medicine extracting solution, a 10% thiotraniliprole suspension, a 10% fluchlorantraniliprole suspension, a 1% celastrus angulatus suspension, prochloraz, potassium fulvate and an organic fertilizer. Before application, the composition is mixed with a surfactant, an antifoaming agent and ethanol to form a microemulsion, and then the microemulsion is sprayed. The macadamia nut-corn interplanting method is combined, dichocrocis punctiferalis is lured to the corn to lay eggs and cause damage, the situation that dichocrocis punctiferalis lay eggs on the macadamia nuts is reduced, pesticide is sprayed in the egg laying peak period, the pesticide can directly make contact with eggs and insect bodies, pests are killed, and therefore the situation that the macadamia nuts are damaged by the insects is reduced, and the purpose of efficient prevention and control is achieved. The agent is mainly prepared from traditional Chinese medicine extract and is compatible with chemical agents, nuts can be protected from being infected by diseases and pests for a long time, meanwhile, the use amount of the chemical agents is reduced, the environment is protected, and the drug resistance of the diseases and pests can be reduced.

The invention discloses a plant nutrition sterilization suspension agent prepared based on natural substances, and particularly relates to the technical field of plant nutrition sterilization, the plant nutrition sterilization suspension agent comprises the following raw materials: a plant mixed extract, a plant ash leachate, a mangosteen shell extract, trace elements, citric acid, hibiscus manihot, animal waste and lotus pond sludge, and the balance of deionized water. The plant mixed extract contains mimosa pudica, celastrus angulatus, garlic, mint, marigold, clove, tea leaves and other raw materials, has a relatively high inhibition effect on wheat powdery mildew, cotton rhizoctonia solani, cucumber angular leaf spot, tobacco mosaic, pythium aphanidermatum and cucumber colletotrichum gloeosporioides, and has the inhibition rate of about 95% on botrytis cinerea and leaf mold of tomatoes; according to the present invention, the antibacterial agent has characteristics of no toxicity, no toxicity and high safety, and the mangosteen shell extract contains more flavonoids and polyphenols, such that the antibacterial effect of the plant can be improved, and the nutritional effect can be provided for the plant.

This invention discloses the application of a compound combination of cypermethrin and Metarhizium anisopliae for the control of the tea leaf beetle. To screen compound agents with synergistic effects against the tea leaf beetle and evaluate their field efficacy, the co-toxicity coefficients of cypermethrin and Metarhizium anisopliae at different ratios were determined using a combined stomach poison and contact toxicity method. Indoor toxicity tests showed that the co-toxicity coefficients of cypermethrin and Metarhizium anisopliae at ratios of 3:2, 4:1, and 7:3 were 178.10, 160.42, and 134.74, respectively, indicating that the compound agent has a synergistic effect on the tea leaf beetle. Considering both co-toxicity and cost, a cypermethrin:Metarhizium anisopliae ratio of 4:1 was selected for field efficacy trials. The results showed that the control efficacy against the tea leaf beetle was 73.98% and 81.87% at 3 and 7 days after treatment, respectively, which was higher than that of single-agent treatments.
