| Abstract: | The test focused on the crystal trichlorfon 90 percent of litura of the effects of pests.The results showed that 90% trichlorfon crystal fresh leaves of the vegetable pests in the 1~3 age of the nymph had best effect,the average effect of up to 85%,the maximum reached 97.8%,we adopted tests also proved that the vegetable leaf trichlorfon pests toxic effects of the stomach was very strong,its effect to an average of 90% or more up to 97%,while BT and microbial pesticides emulsion of the compound was better.T... |
