| Abstract: | The grain bulk was covered with 0.2mm thick PVC in large warehouse (The decline half time was 153s).AlP(6kg) was applied in grain bulk (7866m 3).The results showed that the effective concentration of PH 3 can maintain above 32 days.It can kill all the resistant insects,and had good controlling effect on ovum and pupa,and no insects can be found in 2 years by applyin only once.The concentration ratio of PH 3 reached 0.75 in 31 hours.It also can save 50% costs. |
