| Abstract: | Six pesticides were used to prevent the elder nymph of Drosicha corpulenta in a field experiment, from which four effective methods were confirmed, including 40% monocrotophos, 40% raw omethoate daubing the trunk, 1000-fold of 25% buprofezin WP spraying the crown and trunk,and 150 g of 3% carbofuran particles fertilizering the roots of each tree.Their recti-fying efficacies were 95.0%, 92.9%, 76.0% and 61.6% respectively after 7 days of application. |
