Embodiment approach

[0015] 1. Drug preparation:

[0016] Potassium permanganate, fulvic acid salt, and sodium sulfonate are prepared into a mixed aqueous solution as a liquid medicine, and each liter of the mixed aqueous solution contains 500-1000 mg of potassium permanganate, 1000-2000 mg of fulvic acid salt, and 1000-2000 mg of sodium sulfonate .

[0017] 2. How to use the medicine:

[0018] In the early stage of the disease, apply liquid to the roots of the diseased plants and nearby plants and spray the leaves of the whole field, or spray the watermelon with liquid during the flowering and fruit setting period, once every 5-7 days, for 2 to 3 days in a row. Second-rate. The amount of medicinal solution for root irrigation is 0.25kg per diseased plant; the whole field is sprayed, every 666.7m 2 The volume of the drug solution is 30-50 L.

[0019] 3. Processing effect:

[0020] Compared with the control without treatment, this method can effectively control the Fusarium wilt of watermelon,...

Abstract

The invention relates to a method for preventing and treating watermelon fusarium wilt, which belongs to the field of prevention and treatment of watermelon diseases. According to the technical scheme, the method comprises the following steps of: preparing a potassium permanganate, fulvic acid and fenaminosulf mixed aqueous solution as a liquid medicine; and performing root irrigation on diseased plants and nearby plants with the solution and spraying the solution to the leaves to all watermelons in the full field in the initial disease period, or spraying the solution to the leaves of the watermelons in the blossoming and fruit setting period in the full field for once every 5-7 days and for 2-3 times continuously. The method provided by the invention has the advantages of simpleness in preparation, low cost, low toxicity, no harm, convenience in use, good effect and the like.

Description

technical field [0001] The invention relates to a method for preventing and treating watermelon wilt, and belongs to the technical field of watermelon diseases. Background technique [0002] Fusarium wilt of watermelon, also known as wilting disease and dead seedling disease, is a systemic disease that is transmitted by soil, invades from roots or root necks, and parasitizes in vascular bundles. It is one of the most difficult diseases to control in watermelon production. Often cause large losses. [0003] The disease often occurs after flowering and fruiting. The damaged plants start from the leaves at the base of the stem. The leaves wilt and droop at noon, as if lack of water, and return to normal sooner or later. dying. The base of the main vine of the diseased plant often splits longitudinally, and the surface has a fatty substance overflowing. When the air is humid, the surface of the diseased part produces a white to pink mold layer. Cutting the diseased stem longi...
