常见的菊花蚜虫有菊蚜(Aspiraecolap)和棉蚜(Aphis gossgpii Glover)蚜虫常群集于菊花嫩梢、花蕾和叶背,使叶片皱缩反卷,花朵减少或变小。菊苗受害后延迟生长发育,重者干枯死亡。蚜虫在危害时又不断排泄蜜露,涂布在叶面,阻碍菊花正常生理作用,并易引起病菌寄生,对菊花的生产影响更大。 15％涕灭威颗粒剂,为内吸杀虫、杀螨、杀线虫的药剂。在植物生长期,可埋入土壤或花盆土中施用,药被植物根部吸收后,传导到植物地上部分,对蚜虫、螨类、粉虱、介壳虫、蓟马等刺吸口器害虫防治效果显著。 试验曾选有蚜虫危害的盆栽菊花(花盆内径20公分、内高11公分),每1组处理选用10盆,在花盆内土中,距植株3点对称,挖4—5公分深的穴,各组合每盆分别施0.5、1、2克剂量的涕灭威,然后埋土、灌水、同时设不施药植株为对照。
Common chrysanthemum aphids with aphids (Aspraecolap) and aphids (Aphis gossgpii Glover) aphids often clustered in chrysanthemum shoots, buds and leaves back, so that the leaves shriveled, the flowers reduced or reduced. Jumiao delayed growth after injury, severe cases of death. Aphids also continue to excrete honey dew in the damage, coated on the foliage, hinder the normal physiological role of chrysanthemum, and easily lead to parasitic germs, chrysanthemum production greater impact. 15% aldicarb Granules, for insecticidal, acaricidal, nematicidal agents. In the plant growth period, it can be buried in the soil or pot soil application, the medicine is absorbed by the plant roots, conduction to plant parts of the aphids, mites, whitefly, scale insects, thrips and other stinger suction pest control effect Significant. Aphids have been selected to test the harm of potted chrysanthemum (flower pot diameter of 20 cm, 11 cm high), the treatment of each group selection of 10 pots, pots in the soil, 3:00 from the plant symmetry, dug 4-5 cm deep Points, each combination was applied 0.5,1,2 g dose of aldicarb, and then buried, irrigation, and set no plant as a control.
