From hawkins@empm.cdpr.ca.gov Tue Jul 26 23:07:18 1994 Date: Tue, 26 Jul 1994 11:32:23 -0800 From: Lyndon Hawkins To: sanet-mg@ces.ncsu.edu Subject: Use of hot water to control insects, nematodes, weeds I received a call about the possible use of hot water for control of insects, particularly scales, mealybugs, whiteflies, aphids, etc. on trees, vines and shrubs. I am interested in recent research results indicating efficacy. Please note any recent literature citations or personal experiences. I am familiar with hot water treatments for weed control and hot water dips for nematode control, but I haven't seen anything for insects. Also, is there anyone doing research on efficacy and evaluating different types of equipment for delivering the hot water? Lyndon S.
