and caused erratic weather in the winter months2. On the one hand, insect-pests accelerated the life cycle by the accumulation of more heat units/degree days (DDs) and, on the other hand, caused serious environmental stress to the plant. Prior to this, research has ...
In order to explore controlling measures to Ageratum conyzoides,an exotic and invasive weed,effects of A.conyzoides at different growth stage(vegetative,flowering,fructicative and withering period)on allopelagic soil(0～10cm,10～20 cm) physical and chemical characteristics were studied through pot...
