The Empedobacter brevis GXW15-4 pesticide Is a new type of bacterial pesticide and its insecticidal effect is good.The pesticide is no chemical residue and its safe for people、livestock、birds and Pests natural enemies.It can widely used in preventing and curing the Lepidoptera.Using the Empedobacter brevis GXW15-4 pesticide in pollution-free agricultural products production process can avoid chemical pesticide contamination and improve the quality of agricultural products. The applied range of the Empedobacter brevis GXW15-4 pesticide is wide ,inculding: (1)vegetables:The main pests inculding cabbage caterpillar 、diamondback moth 、noctuid、grain moth、hellula undalis fabricius and Mythimna separata（Walker).Pests of this kind usually feed the leaves of vegetables and affect the normal growth of vegetables.The advanced age Prodenia litura（Fabricius）also can drill in the inside of tomato and green pepper that impacting the quality of the vegetables and market value seriously . (2)rice:The main pests inculding Cnaphalocrocis medinalis Guenee、Sesamia inferens、Chilo suppressalis（Walker）、Tryporyza incertulas (walker) and Casinaria colacae Sonan.The Cnaphalocrocis medinalis Guenee and the Casinaria colacae Sonan seriously affect the photosynthesis of rice by feeding mesophyll of rice, and affect the output final.Sesamia inferens、Chilo suppressalis（Walker）and Tryporyza incertulas (walker) usually drill in the inside of rice and damage nutrition conducting tissue of rice and make the plant dead or can't heading. (3)other botanical beverages:The control efficiency of the Empedobacter brevis GXW15-4 pesticide on other Lepidoptera such as Pyrausta nubilalis (Hubern)、Helicoverpa armigera、pink bollworm、Leguminivora glycinivorella Matsumura 、Cifuna 10cuples Walker、ClanisbilineatatsingtauicaMel1、 Papilio xuthus Linnaeus 、pine moth、Hlyphantria cunea（Drury） and Clostera anachoreta need further development study. (4)Compared with the similar biological pesticide:Compared with the similar biological pesticide Bt ,the Empedobacter brevis GXW15-4 pesticide has some superiorities:①the poisonous force is high, the control effect is good. The relatively toxicity index of the Empedobacter brevis GXW15-4 pesticide is higher than Bt 9% according to the determination result by Nanjing Agricultural University.②Selective insecticidal:the Control target of the Empedobacter brevis GXW15-4 pesticide is Lepidoptera and it's safe for beneficial insect.In the situation of using the Empedobacter brevis GXW15-4 pesticide same amount as Bt unit area（16000IU/mg,that is per hectare using 750 ml）, the average control effect of the Empedobacter brevis GXW15-4 pesticide is 80.24% while the Bt is 76.86%,so the control effect of the Empedobacter brevis GXW15-4 pesticide is higher than Bt 3.38%. So the control effect of the empedobacter brevis gxw 15-4 pesticide is higher than Bt 3.38%.of the empedobacter brevis GXW15-4 pesticide is Lepidoptera and it's safe for benefocial insect.in the situation of |
