| Abstract: | The control effect of 12a-hydroxy-rotenone emulsifiable concentrate (EC) against four pests of cruciferous vegetable (larva of Plutella xylostella, Myzus persicae,Pieris rapae and adult of Phyllotreta striolata) was studied through field experiment.The results showed that 12a-hydroxy-rotenone EC had a great control effect against these four pests showed above.At the third day after treatment,the control efficiency against adult of Phyllotreta striolata,Myzus persicae,Pieris rapae and larva of Plutella xylostella was 93.6%,98.3%,84.3% and 87.6%,respectively.To control these four pests,10% 12a-hydroxy-rotenone EC not only had high control efficiency,but also had faster and longer control effect than that of control (52.5% Nurelle EC).There was no phytotoxicity when applying hish dosage of 12a-hydroxy-rotenone EC,so it is safety to use in the crops.Therefore,12a-hydroxy-rotenone EC is recommended to control the pests of cruciferous vegetable. |
