| Abstract: | Control of Dendrolimus punctatus by 2. 25kg/hm2 of Sulijing with 32 000 DPIU/mg of poisonous coefficient of primitive powder and micro-capsule powder and 200~300 billion fungi/g with the ratio of 1: 40 ~80(light calcium carbonate) : 0. 16 ~0. 3(sodium benzonic acid)resulted 70. 0%~91. 1% of population decrease on the loth day after treatment. but 83. 6%~98. 3% of population decrease on the 25th day, the average reached 94%. Rectified control effect was 68. 9%~96. 8%, average was 88. 6%. Control 'of D. punctatus by Sulijng had advantages of small dose, low cost(28. 05yuan RMB/hm2 ). good effect, protecting natural ennemy and no pollution. |
