The pathogen is a fungus that is a semi-known fungus of the genus Botrytis. The bacterium sclerotia or conidia overwintered in the soil with the diseased plant residues. Under high temperature and rain conditions, it is conducive to diseases.
1. Injury symptoms
1.1 The disease can cause rotten leaves, stems and flowers in various parts, causing the plant to die.
1.2 First of all, dark green, water-stained markings appear on the margins of the leaves and gradually spread to the entire leaves. The leaves are brown and dry.
1.3 When the humidity is high, the gray mold layer grows in the decayed part, and the petiole and pedicel will also be mild and rotten, resulting in a moldy layer.
2. Control technology
2.1 Using new soil or disinfecting soil, the soil is disinfected with equal amounts of quintozene and zinc sulphate and mixed in the noodles, with a dosage of 8 to 10 grams per square meter.
2.2 Timely?[Except for diseased leaves or diseased plants, they are destroyed centrally.
2.3 control room temperature and humidity, pay attention to ventilation.
2.4 In the early stage of disease, 1:1:200 equal amount of Bordeaux mixture can be used; or 65% of Zeisonic Zinc WP can be used 500 times; or 50% of carbendazim WP can be sprayed and controlled 500 times. Every 7 to 10 days, 2 or 3 times in a row.
Trichloroethylene Recycling Machine
Trichloroethylene Recycling Machine,Calstar® Solvent Recovery Machine Recyclable: washing solvent, acetic acid esters, halogenated hydrocarbons, three ethyl chloride, trichloroethylene, solvent oil, isopropyl alcohol, acetone, butanone and cyclohexanone, days that water, wash water gun, banana water, plate washer water, wash water network, wash water, white oil, hand washing water, diluent, washing water, ink cleaning agent, ethyl acetate, toluene, xylene, toluene three, four toluene, banana water, alcohol, ethanol, butanol, two glycol solvent waste and dirty etc..
Calstar® solvent recovery machine using the distillation principle: by heating the evaporation of solvent into a gaseous state, the steam into the cooling system to flow out, so that the recovery of organic solvents. So as to make the waste, dirty, old organic solvent recycling, recycling and reuse. Both can save a lot of procurement costs, but also to reduce the pollution of the environment.
