Citrus leafminer (Phyllocnistis citrella) is one of the major citrus pests. In 1981, we applied pyrethroid pesticides to control large-scale prevention and control experiments at low dosage, held the appraisal in the autumn to promote the use of the province, and the prevention and treatment effect was remarkable. In 1982, a large area demonstration of evidence was continued and the results of large-scale promotion and use were investigated. Preliminary statistics The province to promote an area of about 20 million mu, accounting for about 40% of the province’s total citrus, reaching an exceptionally significant control effect. MATERIALS AND METHODS 1. Pharmacy categories: 20% fenvalerate emulsion, 20% pyrethrin emulsion (Shanghai Fourteen Pharmaceutical Factory), 20% suicidin (Sumicidin 20EC, Japan), 2.5% (Decis 2.5EC from France), 25% Cypermethrin Emulsion (Cymbush 25EC from England), 25% Quetiaprene Emulsion (from Ekalux 25EC from Switzerland), 50%
