Abstract


The CIBA-GEIGY Corporation is the U.S. subsidiary of CIBA-GEIGY Limited, Basel, Switzerland, one of the largest agricultural chemical companies in the world. The focus of the Insect Control Sector is toward newer, safer technologies that fit into IPM programs and are socially and environmentally acceptable. As part of this strategy CIBA-GEIGY has major efforts in biological control, with priorities in Bacillus thuringiensis, Beauveria bassiana and Trichogramma spp. research. CIBA-GEIGY's first Bacillus thuringiensis product, coded CGA-237218, is a transconjugate from Bacillus thuringiensis subsp. aizawai and Bacillus thuringiensis subsp. kurstaki parents. This transconjugate strain shows increased lepidopteran activity over that of the parental strains, especially against pests in the genera Heliothis, Spodoptera, Pieris, and Mamestra. EPA approval is expected in 1992. A cooperative effort between CIBA-GEIGY and the University of Florida is in the progress to develop a commercial Beauveria bassiana product for control of the citrus root weevil complex in citrus. CIBA-GEIGY also has cooperative projects underway with Canadian institutions and the USDA to develop the parasitic wasp, Trichogramma minutum, for control of the eastern spruce budworm, Choristoneura fumiferana, an economically important pest of Canadian forests.
