The present application relates to a kind of insecticidal compositions containing flonicamid and celangulin, wherein the weight percentage of effective component flonicamid and celangulin is 1-80:10-0.1, which can be further preferred as 10-60:5-0.1.The total mass of two effective components flonicamid and celangulin accounts for 1%-90% of the mass of the entire preparation, which can be further preferred as 10-60%, and the rest is the common adjuvant or filler in pesticides.The insecticidal composition of the present application can be prepared into suspension concentrate, water dispersible granules, water emulsion, microemulsion, emulsifiable concentrate and wettable powder and other dosage forms.The present application carries out binary compounding of flonicamid and celangulin, has obvious synergistic effect, and the quick-acting and long-acting properties of pesticide are good, and reduces production cost and use cost, and is especially suitable for the prevention and treatment of thrips.

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.
