The method has extremely high industrial application value, and can ensure stable potted flower cultivation quality.

The invention relates to a Lipu taro pest control method and pesticide spraying equipment, and the method comprises the following steps: carrying out primary ploughing on a planting land, and exposing the soil in the sun for 15-20 days; turning over for the second time, and meanwhile, applying fully decomposed farmyard manure and plant ash; a groove is dug in the edge of the planting field, a water storage tank surrounding the planting field is constructed, and water guided into the water storage tank is disinfected; preparing a liquid medicine from metalaxyl or carbendazim according to a set proportion, soaking the seed taros for 15-30 minutes, sterilizing, airing, and sowing; according to the method, dimethomorph, cymoxanil or fluopicolide propamocarb are prepared into liquid medicine according to a set proportion, and the liquid medicine is sprayed to the taros once every 7-10 days through spraying equipment and is continuously sprayed for 2-3 times; hymexazol or metalaxyl mancozeb is selected for root irrigation treatment, and 200-300 ml of hymexazol or metalaxyl mancozeb is metered for each plant. Compared with the prior art, repeated epidemic diseases are prevented, and the epidemic disease control effect is improved.

The present invention relates to a method for identifying drug-resistant Candida albicans and an identification kit. Candida albicans is a common pathogen. Clinical treatment for fungal infections should first be carried out on the strains for typing detection, and appropriate antifungal drug treatment should be selected based on the drug sensitivity results. Currently, drug sensitivity culture requires a long time. To address this shortcoming, the present invention provides a method for identifying drug-resistant Candida albicans. The strain to be identified is incubated with MKT077 and benomyl, and the degree of rightward shift of the red fluorescence of the strain after incubation is detected. The strain showing a significant rightward shift is Mdr1-type Candida albicans. This identification method has good specificity and fast detection speed. Its application in clinical testing can effectively shorten the time required for detection and has promotional value.

This application relates to a fungicide composition containing tetraflufenazole and benomyl, the composition comprising: (a) a liquid tetraflufenazole active ingredient at room temperature; (b) a solid benomyl active ingredient at room temperature; (c) a [2,4,6-tris(1-phenylethyl)phenyl] ether polymerized from ethylene oxide and propylene oxide; and (d) an optional functional surfactant. The [2,4,6-tris(1-phenylethyl)phenyl] ether polymerized from ethylene oxide and propylene oxide effectively solves the storage compatibility problem between the two different forms of tetraflufenazole and benomyl, especially addressing the issue of mutual aggregation and sedimentation between the oil droplet form of tetraflufenazole and the particulate form of benomyl during dilution after storage, reducing the risk of sprayer clogging. The fungicide composition of this application effectively solves the compatibility problem between the liquid tetraflufenazole active ingredient and the solid benomyl, and the prepared product exhibits good performance in storage stability.

The invention discloses a solid-liquid separation process for producing carbendazim, and belongs to the field of pesticide production. The solid-liquid separation process comprises the following process steps: preparing carbendazim through a methyl chloroformate synthesis method to obtain an original feed liquid, performing primary membrane separation, mixing an ethanol water solution, performing secondary membrane separation, recovering and drying to obtain a carbendazim solid. A two-time membrane separation method is adopted for classified screening, primary membrane separation can quickly separate most of carbendazim crystals with conventional sizes in original feed liquid, large-particle-size crystals are prevented from blocking tiny pores of secondary membrane separation, then the carbendazim crystals are blended with an ethanol water solution, the solubility of organic impurities is improved, and the separation efficiency is improved. The method comprises the following steps of: separating crystals by using a membrane, effectively stripping impurities on the surfaces of the crystals, deeply washing the crystals, finally separating by using a secondary membrane, intercepting submicron fine crystals, deeply intercepting the microcrystals in a targeted manner, effectively adsorbing and removing the impurities, and improving the yield and the purity of products.

The invention provides a three-in-one efficient solidago canadensis prevention and treatment method with seasonal pertinence, which comprises the following steps: firstly, cutting an overground part in a full-bloom stage or before autumn, and spraying glyphosate in spring to prevent residual seeds in a soil seed bank from germinating; then, in winter, benomyl is applied to break interaction of arbuscular mycorrhizal fungi and solidago canadensis, and after overground branches germinate in spring, a glyphosate solution is sprayed to leaves; and finally, after the overground part is withered, removing residual vigorous subterranean stems to prevent recurrence in the next year. According to the method, invasion weed prevention and control are carried out by trinity comprehensive utilization of physical, chemical and biological prevention and control methods and combination of growth characteristics of plants and microorganisms in different seasons from seed diffusion of solidago canadensis, overground plants and interaction relation between subterraneous stems and soil microorganisms, the prevention and control effect is excellent, the cost and labor force can be reduced, and the method is suitable for large-scale popularization and application.
