In vitro sensitivity of antagonistic Trichoderma atroviride to herbicides BABT
Santoro,Patricia Helena; Cavaguchi,Silvia Akimi; Alexandre,Talita Moretto; Zorzetti,Janaina; Neves,Pedro Manuel Oliveira Janeiro.
Trichoderma atroviride was tested in vitro for its sensitivity to different herbicides. The dosages tested were recommended dosage (RD), half dosage (½RD), and double dosage (2RD). Germination, colony-forming units (CFU), radial growth, and spore production were evaluated. Carfentrazone-ethyl and sulfentrazone inhibited the germination at RD and 2RD. A reduction in the CFU was observed for glufosinate-ammonium, atrazine, carfentrazone-ethyl, diuron + paraquat dichloride, imazapyr, oxyfluorfen, and sulfentrazone at each of the tested dosages. Radial growth was influenced by ametryn, atrazine, carfentrazone-ethyl, oxyfluorfen, and sulfentrazone herbicides, with an 80% reduction of the colonial area. Spore production was affected by carfentrazone-ethyl,...

Non-pesticide Methods for Controlling Plant Diseases andInsect Pests in Chinese Taipei Taiwan Agricultural Research Institute
Tze-Chung Huang.
[[abstract]]Located in subtropical area, Taiwan has warm and humid climate that is suitable for the occurrence of plant diseases and insect pests. Farmers in Taiwan were used to controlling diseases and insect pests with pesticides that might result in problems of chemical residue, pesticide resistance and environmental pollution. In order to minimize the negative effects caused by the use of pesticides, plant protection institutions have started intensive researches and extensions of non-pesticide methods since early 1970¡¦s. The top authority of plant protection, Council of Agriculture (COA), has set the development and extension of non-pesticide methods as a national strategic plan since 1984. With the efforts over the past few years, we have promoted...
