| Abstract: | The experiment showed that the control effect of low volume spray of 16 000 IUmg Bt WP at the dosage of 1 500 ghm~2 and 1 200 ghm~2 against Apocheima cinerarius in the natural forests of Populus erphratica by Y-5B airplanes was high and longlasting.The application of 1 200 ghm~2 can kill 97% of the pest.The harm of Apocheima cinerarius in the natural forests of Populus euphratica decreased rapidly.And the cost was lower. |
