چکیده
Two types of Trichoderma longibrachiatum Tr58 propagules, conidia and chlamydospores, were added to soils with different moisture levels. The survival dynamics in determined. There are positive linear relationships between soil levels germination rates the two propagules. In natural non-sterilized soil, more than 95% 60% chlamydospores was inhibited, while a high content sterilization beneficial spore germination. inhibitory effect 80% on almost completely eliminated after sterilization. Twelve months inoculated propagules decreased continuously, which hastened lower near zero 24 later, all soils. chlamydospore-amended soils, generally showed dynamic process decreasing first month, increasing 2nd then gradually. average 5, 10, 20, 40, 19.2 times that conidia-amended at 12 months. At months, about 2.2% initial 114 20% content. However, for content, 0.0038% Tr58. According results this study, 10–20% most favorable long-term Tr58, ability stronger had greater application potential disease control.

The use of pesticides in modern agriculture is unavoidable because they are required to control weeds. Pesticides are poisonous; hence, they are dangerous if misused. Understanding the fate of pesticides will be useful to use them safely. Therefore, contaminations of water and soil resources could be avoided. The fates of pesticides in soils are influenced by their sorption, decomposition and m...
