Forget-me-not root rotdiseaseIn fact, many flower lovers grow flowers to appreciate the above-ground parts. As for what the underground rhizomes look like, it seems to have nothing to do with you, but the growth of the roots is closely related to the stems and leaves of the flowers above ground. Once forget-me-not is infected with root rot, the roots gradually turn black and rot, the absorption capacity decreases, and it is unable to receive nutrients, let alone transport nutrients to the stems and leaves, causing the plant to gradually wilt and turn yellow. Prevention and treatment methodsIf the root rot is not serious, remove the plant from the pot, cut off the rotten part, soak it in potassium permanganate solution, and replant it. Then spray 500 times diluted 60% succinate-fosfosetyl aluminum wettable powder. Forget-me-not brown spotdiseaseThe leaves of common forget-me-not are not obvious and look small and inconspicuous, but leaves are indispensable. Forget-me-not brown spot disease mainly harms the leaves, causing brown spots to appear, yellowing and falling off, affecting the ornamental value. In severe cases, it can damage the stems, causing spots and even rot. Prevention and treatment methodsStrengthen maintenance, do not water too much, increase ventilation and reduce humidity. Remove diseased leaves promptly if found to avoid further infection. In the early stage of the disease, 65% Zineb wettable powder 600-800 times diluted or 50% Carbendazim wettable powder 600-800 times diluted can be sprayed. Forget-Me-Not Pest ControlThe pests of forget-me-nots mainly gather underground, common ones include cutworms, mole crickets, white grubs, etc., but mites are the most serious harm in the home. In addition to directly sucking the sap of the plant and causing damage, they also mainly spread viral diseases. Therefore, early detection and early treatment are necessary, and bactericidal agents should be used for irrigation in time to avoid the occurrence of viral diseases. |
