INSPECTION AND DAMAGE THRESHOED. Infestation is monitored by means of the knockdown test. The brown leaf weevil has occurred in very large numbers in recent years. Knockdown tests with 200-300 brown leaf weevil beetles/100 branches are quite common. 

L ves with notched leaf margins. Cause Japanese weevils. The A", brown adults attack foliage, and the legless white grubs feed on roots. Apply a sticky substance, such as Tanglefoot, to the lower stems to prevent adults from climbing up the plants. Drench the soil around the base of the plant with a solution of parasitic nematodes to control the larvae. Spray leaves several times with pyrethrin for major infestations of adults.
