Lilium pest control method
Lily pests are mainly aphids, beetles and so on. In addition, there are root-knot nematodes, ground tigers and other hazards.
Aphids and peaches are the most common aphids in plants. Prevention and control: eliminate the source of overwintering insects, remove nearby weeds, and thoroughly clear the garden and fields. Spray 40% dimethoate or omethoate 1200 times, or aphid pine emulsion 1500 times, or 2.5% fish essence 1000 times 1500 times during the aphid damage period. To protect natural enemies is to protect seven-star ladybugs, aphid flies and lacewings.
Grub is the larva of beetle shell, which is an important underground pest which can harm many kinds of plants in soil.
Prevention and control: deep turning over flower beds and flower bed soil in winter can increase the death of overwintering insects. During the harmful period, you can apply 50% marathon emulsion 800 / 1000 times or malathion 800 / 1000 times, both of which have good results.
Biological control. At present, the use of milky bacteria in foreign countries and Metarhizium anisopliae in China has a good experimental effect on the control of broad-chest rhinoceros, which is a good beginning of using beneficial fungi to control underground pests.
