Bio-efficacy of sincocin AGTM to controlTylenchulus semipenetrans (Tylenchida,Nematoda) in citrus orchard

Field experiment was conducted at a site naturally infested withTylenchulus semipenetrans to explore the effect of sincocin AGTM as a biocidal agent at 2000 ppm in controlling citrus nematodes. Sincocin AGTM significantly reduced citrus nematode population in both soil and roots ofCitrus sinesis, and enhanced both growth of orange trees and soil mites especially the mesostigmatide mites. In treated soil, the nature nematode feeders, mesostigmatide mites were increased by 140% and 243%, one month and two months, respectively, post application.
