The invention discloses an application of a low peat substrate in Australian fox tail cultivation. The planting substrate is prepared according to the EC value of the mushroom residues and is not limited by the decomposition degree of the mushroom residues. When the EC value of the mushroom residues is less than or equal to 2.0 mS / cm, the safe range of the addition volume ratio is less than or equal to 30%; the EC value is (2.0-3.0) mS / cm, and the safe range of the addition volume ratio is less than or equal to 20%; the EC value is (3.0-4.0) mS / cm, and the safe range of the addition volume ratio is less than or equal to 5%; the EC value is (4.0-5.0) mS / cm, and the safe range of the addition volume ratio is less than or equal to 3%; eCgt; 5.0 mS / cm, and no mushroom residue is added; meanwhile, an aqueous solution of carbendazim, spring Leiyujin A particles and efficient cyfluthrin is used for rooting water, and a complex agent of trichoderma harzianum and a matrine aqueous solution is thoroughly watered on the tenth day after field planting. The method has extremely high industrial application value, and can ensure stable potted flower cultivation quality.

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.
