What are the control methods for lily pests?

The main lily pests include aphids, scarab beetles and others. In addition, there are also damage from root-knot nematodes, cutworms and others.

The peach aphid is the most widespread aphid pest on plants. Control: eliminate overwintering sources of the pest, clear away nearby weeds, and carry out thorough clearing of the garden and field. During the aphid damage period, spray 40% dimethoate or omethoate at 1200 times dilution, or aphid-killing pine emulsion at 1500 times, or 2.5% fish essence at 1000-1500 times. Protect natural enemies, that is, protect the seven-spot ladybird, hoverflies and green lacewings, etc.

White grubs are the larvae of scarab beetles; the larvae that mainly live in the soil and can harm many kinds of plants are important underground pests.

Control: deep-dig the soil of flower nurseries and flower beds in winter, which can increase the death of overwintering insects. During the damage period, shallow application of 50% malathion emulsion at 800-1000 times or malathion at 800-1000 times both give good results.

Biological control. At present, the use of Milky Disease bacteria abroad and the use of Metarhizium anisopliae for scarab beetles in China to control the broad-breasted rhinoceros beetle have both shown good experimental results, and this is a good beginning for using beneficial fungi to control underground pests.
