The invention discloses a pesticidal main agent and a pesticide by compounding destruxins of Metarrhizium anisopliae and high-efficiency cypermethrin. The mass ratio of the destruxins of Metarrhizium anisopliae to the high-efficiency cypermethrin in the main agent is 7-1:3-9. The invention adopts pyrethroid pesticide with high efficiency, low toxicity, low residue and broad spectrum activity, namely the high-efficiency cypermethrin, and entomopathogenic fungi with obvious disinsection effect, namely the destruxins of Metarrhizium anisopliae, for compounding to obtain the pesticidal main agent, and determines the preferable compounding ratio of both through a large number of experiments. The pesticide has brand-new action mechanism different from the prior pesticides and obvious disinsection effect, particularly has obvious toxic action on prodenia litura which has severe harm, and has the characteristic of environmental protection at the same time.

The invention relates to the use of tubatoxin in preparation of drugs treating acute kidney injury. After treatment with a small dose (250ppm) of tubatoxin, the mouse kidney injury situation can be obviously improved, and the levels of blood urea nitrogen (BUN) enzyme and creatinine (Cr) are obviously lowered.

The invention discloses a Serratia marcescens PS-1 strain isolated from Flea beetle flavus and application thereof. The present invention directly isolates a strain of Serratia marcescens (Serratia marcescens) strain from the body of the diseased flea beetle larva for the first time, which was preserved in the General Microbiology Center of China Microbiology Culture Collection Management Committee on July 22, 2013. The number is CGMCC No.7948. The Serratia marcescens PS-1 strain has strong pathogenicity to the larvae and adults of the flavonoid beetle and the larvae and adults of the beet armyworm, and can effectively control the development of the experimental population of the beet armyworm. The invention provides a technical basis for the field population control of the flea beetle and the beet armyworm, and is important for safely, effectively and sustainably controlling the flea beetle and the beet armyworm, and effectively ensuring the yield and quality of vegetables practical significance and practical value.

The invention relates to the field of plant breeding, in particular to a polyploid induction method of juncus effusus. The method is characterized in that in the process of mutagenesis, a sterile explant is selected, pretreated with a high-concentration mutagenic agent firstly and then transferred to a proliferation medium containing a low-concentration mutagenic agent for culture, and mutagenic test-tube seedlings are obtained in the shortest time. The method has the advantages of being good in stability, convenient to operate and high in mutation efficiency.

The invention belongs to the technical field of botanical pesticides, and discloses a botanical compounded insecticide for root-knot nematode incognita and a preparation method thereof. The water extract of chrysanthemum chrysanthemum, lice grass water extract and Houttuynia cordata water extract, the present invention realizes the synergistic effect of killing root-knot nematodes by compounding various plant extracts, shortening the time of killing insects, It can effectively increase the mortality of pests while reducing the amount of pesticides. Moreover, only neutral distilled water needs to be used as the extractant in the preparation process, which saves cost and is easy to operate.

The present invention discloses a pesticide compounding beauveria bassiana fungus and destruxin. The pesticide is prepared by mixing the beauveria bassiana fungus, the destruxin and solvent, the concentration of live conidia of the beauveria bassiana fungus after mixing ranges from 10<7> to 10<11> conidia per liter, and the pesticidal effect is better when the concentration of the destruxin ranges from 10 mg / L to 100 mg / L. The preparation method for the pesticide comprises the following steps: preparing conidial suspension of the beauveria bassiana fungus, preparing destruxin stock solution, mixing the conidial suspension and the destruxin stock solution, and the like. The invention selects the beauveria bassiana fungus to be used with the destruxin in a mixing way for synergic action, and the pesticide has the completely new function mechanism different form the prior pesticide, has an excellent pesticidal effect particularly in poisoning and killing bemisia tabaci gennadius with serious harm, and meanwhile is environment-friendly.

The invention relates to a ZIF-L-based epoxy resin composite coating, a preparation method, and a coating product, and relates to the technical field of coatings and surface coatings. The main technical scheme adopted is: the epoxy resin composite coating based on ZIF-L comprises: two-dimensional metal organic framework material ZIF-L nanoparticles, 8-hydroxyquinoline-terminated aniline trimer, epoxy resin coating body . Wherein, in the epoxy resin composite coating based on ZIF-L: the mass fraction of the two-dimensional metal-organic framework material ZIF-L nanoparticles is 0.1-10wt%; the 8-hydroxyquinoline-terminated aniline trimer The mass of 2D metal-organic framework material ZIF‑L nanoparticles is 5‑50%.
