Lily common disease control method

First, soft rot. Damage to the bulb, making the bulb rot, and emitting an unpleasant stench, serious when the temperature is high and humidity is high, the damage is rampant and spreads rapidly. Before planting, select non-invasive bulbs and soak them in 0.1% potassium permanganate aqueous solution for 10 minutes.

Second, blight. Damage to the bulb and root system, so that the bulb rot, root rot, and finally the plant died upright. Before planting, pay attention to select the disease-free bulb, and soak the bulb in 0.1% limewater clarification solution for 10 minutes for disinfection. In the process of field management, it is necessary to increase the application of phosphorus and potassium fertilizer and avoid partial application of nitrogen fertilizer in order to improve the ability of disease resistance. Generally, potassium dihydrogen phosphate or high-efficiency biological phosphorus and potassium fertilizer is applied to the roots once a month, 25ml 30g per plant, mixed with water or retting to make rotten human and animal dung water 2ml 3kg and then drenched. After the disease occurred in the field, the root was irrigated with 600x dimethasone solution or 1000 times cupric sulfate solution, once every 7murl for 10 days, for 3 times in a row, each time about 2ml / plant.

Third, leaf spot. In order to harm the leaves, after the appearance of water-stained dark brown disease spots on the leaf surface, the leaves lost green, yellowed and withered, died and fell off. When dark brown water stains appear on the leaves, it is necessary to spray 1000 times maleic acid dehydration solution, or 1000 times bromozole water solution, or 800x leaf spot clean water solution on the leaf surface continuously for 3 times, once every 10 days, to wet all leaves evenly, so that water droplets begin to drip down the leaves and infiltrate into the root soil, that is, the occurrence and damage of leaf spot can be controlled.

Fourth, gray mold. In order to harm the buds and flowers, after the buds and flowers are covered with yellowish gray mold, the buds shrink and fall off, and the flowers rot and wither. It is easy to get sick in a humid environment. When a yellowish gray mold appears on the buds and flowers, it is necessary to continuously spray 2 Mel 3 times 1000 times Sukeling aqueous solution, or 1000 times Curd aqueous solution, or 1000 times Botrytis cinerea pure water solution, once every 7 times every 10 days, pay attention to spray on the buds and flowers, so that it is appropriate to begin to drip down.

5. Virus. Damage to the whole plant, resulting in no new roots, new leaves are not long, the longer the smaller, the leaves are short clumps, and gradually yellowing, withering, death. In the process of lily growth, it is generally necessary to spray 600 times plant virus vaccine solution or 600 times virus purified solution or 600 times virus solution once a month, about 2k per plant, or wet leaves dripping water, in order to weaken the virus activity in the plant and effectively prevent the disease of the plant.

Aphids, red spiders, scale insects, whitefly. In order to harm leaves, prick and suck juice, spread virus disease, cause plant decline, and affect arrow flowering, 1000 times aphid lice solution, or 1000 times Lex solution, or 1000 times farmland solution, must be sprayed on the leaves once a month to protect the leaves.

Grubs, mole crickets, crickets and small tigers. All of them are underground pests, which bite the underground roots and make the plants lodge and die. The roots must be sprayed once a month with 1000 folds of Lesbon aqueous solution, or 800x trichlorfon aqueous solution, or 25Mel 30x dry and pure plant ash extract, or 10mi 15x retting mature rabbit dung aqueous solution for control, each time each plant solution is about 2k ~ 3kg.
