As can be seen from Table 2, rotenone and indenes worm prestige are mixed, and co-toxicity coefficient is greater than 100, show that rotenone and indenes worm prestige rationally are mixed and have synergistic effect.
Embodiment 12 rotenone and indenes worm prestige mixed insecticide preparation effect experiment result:
Experiment one: after 15% rotenone and indenes worm prestige microemulsion, 2.5% rotenone emulsifiable solution and 15% indenes worm prestige suspending agent diluted 5000 times, 500 times, 1500 times respectively the diamond-back moth spraying is handled, then investigation in the 1st, 3,7,14 day and calculating preventive effect after medication.
5000 times of 15% rotenone and indenes worm prestige microemulsion to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 70.2%, 87.5%, 98.9%, 90.7%; 500 times of 2.5% rotenone emulsifiable solution to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 18.7%, 55.0%, 71.1%, 73.2%; 1500 times of 15% indenes worm prestige suspending agent to the diamondback moth larvae medication after the 1st, 3,7,14 day preventive effect be respectively 56.7%, 69.5%, 84.3%, 65.8%.
Experiment two: after 3% rotenone and indenes worm prestige missible oil, 2.5% rotenone emulsifiable solution and 15% indenes worm prestige suspending agent diluted 1500 times, 500 times, 1500 times respectively the prodenia litura spraying is handled, then investigation in the 1st, 3,7,14 day and calculating preventive effect after medication.
1500 times of 3% rotenone and indenes worm prestige missible oil to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 72.2%, 89.2%, 98.3%, 93.3%; 500 times of 2.5% rotenone emulsifiable solution to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 28.7%, 45.3%, 61.7%, 76.2%; 1500 times of 15% indenes worm prestige suspending agent to the Spodoptera litura larvae medication after the 1st, 3,7,14 day preventive effect be respectively 55.7%, 68.3%, 85.1%, 66.7%.
From above-mentioned test of pesticide effectiveness explanation agricultural chemicals that the present invention was mixed and the contrast of former agricultural chemicals, the lasting period that the control of insect is had remarkable control efficiency and length.
