Last Updated: 2024/11/25, Botrytis cinerea, anthracnose and blight are common diseases in Liliaceae. If it is not prevented in time, it will lead to a reduction in production. The main results are as follows: (1) Botrytis cinerea, also known as leaf blight, belongs to semi-known fungi. It mainly occurs on stems, leaves and flowers, which often harms the tip of young leaves and makes the growth point of the stem soft and rotten. If it occurs in the leaves, yellow or reddish brown spots will be formed, and the periphery is flooded. The weather is humid and the disease department produces gray mildew. Prevention and treatment: spray 1V / 150 Bordeaux solution or mancozeb 600 / 800 / 800 times at the initial stage of the disease and spray continuously for 2 ~

Botrytis cinerea, anthracnose and blight are common diseases in Liliaceae. If it is not prevented in time, it will lead to a reduction in production.

The main results are as follows: (1) Botrytis cinerea, also known as leaf blight, belongs to semi-known fungi. It mainly occurs on stems, leaves and flowers, which often harms the tip of young leaves and makes the growth point of the stem soft and rotten. If it occurs in the leaves, yellow or reddish brown spots will be formed, and the periphery is flooded. The weather is humid and the disease department produces gray mildew. Prevention and treatment: at the initial stage of the disease, spray 1V 150 times Bordeaux solution or mancozeb 600 times 800 times, spray 2 times continuously for 3 times.

(2) anthrax is a semi-known fungus, which mainly infects leaves, flowers and bulbs. The disease occurred in the leaves, resulting in oval, light green, surrounding yellowish-brown spots and central depression. Bulb disease, the lateral scales produce reddish irregular spots, the boundary between disease and health is obvious, and then the spots become dark brown and sclerotic. Prevention and treatment: choose disease-free bulbs as seeds, and disinfect the planted bulbs. The disease in the field can be irrigated with 1000 times of carbendazim.

(3) Phytophthora is also a kind of fungal disease. Can impregnate leaves, stems, flowers, bulbs. Stem damage, the emergence of water-stained light brown disease spots, gradually upward and downward expansion, resulting in stem rot, leaf withering and death. When the disease is serious, the flowers, stem bases and scales can be killed, resulting in the destruction of the whole field, and the disease is serious in the hot and humid season. Prevention and treatment: spraying 25% Ruidu 800 times liquid at the initial stage of the disease, and then spraying metalaxyl manganese zinc, Yimaoling and other agents, the cross-use effect is better.

(4) the main pest of mountain lily is aphid. Aphids often gather on tender leaves and flower buds to draw juice, resulting in stem atrophy, poor growth and affected flowering and fruiting. Spraying 40% dimethoate emulsion 800-1000 times during the occurrence period has an excellent control effect.
