IPM in Soybean Dr. Amar N. Sharma Principal Scientist (Entomology) Directorate of Soybean Research (ICAR) Indore (MP)

IPM !!!!!!!!!!!

Integrated Pest Management Integrated use of all possible measures to keep insect-pest population below ETL

Limitations in adoption of IPM  Lack of awareness  Easy access to chemical insecticides  Inadequate production of bio-control agents  Farmers’ economic status  Lack of incentives  Limited area under IPM Then why IPM ?????

Demonstrated Feasibility and economics

Multi-location IPM Module 1: Recommended dose of fertilizers, Seed treatment with Rhizobium, PSB and Trichoderma, Bird-perches Pheromone traps Removal of girdle beetle, Spodoptera and D. obliqua infested plants/plant parts, Foliar application of Bt or B. 1.0 kg/ha, and Need based application of chemical insecticides

Module 2: Recommended dose of fertilizer, Seed treatment with Rhizobium, PSB and Trichoderma, Spray of Ha NPV or Sl 250 LE/ha, Spray of N. rileyi or 1.0 l/ha, Spray of 5%, Need based application of chemical insecticides

Measures to reduce insect infestation Deep summer ploughing Selection of proper variety Balanced nutrition Proper seed rate & spacing Use of Improved Light Traps

Use of Pheromone Traps

Bird perches

Management of Soybean insect-pests Removal of infested plants

Use of Microbial insecticides Bt based: Dipel, Biobit, Halt, 1.0 kg/ha, or Bb based: Biorin, Biosoft, Larvocel, 1.0 kg/ha, or Virus based: HaNPV / 250 LE/ha

Comparative Performance of B.t. Formulations Larvae / mrl (Mean 10 DAT) Average Larval Population on 1 DBT = /mrl

Overall Performance of B.t. Formulations Larvae / mrl Average Larval Population on 1 DBT = 9.13 / mrl Average Larval Population in Control = / mrl

Compatibility of Bt with Chemical Insecticides Bt based microbial insecticides are compatible with chemical insecticides like – Monocrotophos, Thiamethoxam, Methomyl and Lufenuron, And with fungicides like – Carbendazim, Thiophenate methyl and Triadimefon Mixture of Bt and Monocrotophos is also compatible with Carbendazim and Thiophenate methyl

Exploitation of Natural Enemies

Natural enemiesHost insectPotential Parasitoids (Appanteles, Trichogramma, Brachymeria, Bracon, Sturmia spp.) C. acuta, D. orichalcea, S. litura, H. armigera 5 to 30 % larval mortality Predators (Cantheconidia furcellata, Chrysoperla carnea) C. acuta, D. orichalcea, S. Litura 10 to 12 % larval predation Insect Pathogens (B. bassiana. N. rileyi, Bt & NPV) C. acuta, D. orichalcea, S. litura, H. armigera 15 to 100 % larval mortality Potential of Natural Enemies

Success Stories in biological control Papaya mealy bug (Paracoccus marginatus) control through Acerophagus papayae) Sugarcane woolly aphid (Ceratovacuna lanigera) control through predators (Dipha aphidivora or Micromus igorotus)

Entomopathogenic nematodes (EPNs) Symbiotic bacteria associated with EPNs:  Xenorhabdus sp. with Steinernematids,  Photorhabdus sp. with Heterorhabditids
