Evaluation of IPM Modules for Tomato

Evaluation of IPM Modules for Tomato

Tomato (Lycopersicon esculantum Miller) is one of the most popular solanaceous vegetable crop widely grown in the world, because of it’s wide adaptability to different climatic conditions and high yield potential.

The productivity of tomato crop in India is alarmingly low, when the production potential of the crop in the developed countries is taken into consideration. There are many constraints for lower production of tomato amongst the pest infestation is major one. There are number of insect pests recorded infesting tomato crop by different research workers in India, but out of them some play a major role in reducing yield. They include tomato fruit borer (Helicoverpa amigera Hubner), whitefly (Bemisia tabaci Gen.), thrips (Thrips tabaci Lind.), aphids (Aphis glossupii Glov.), mites (Tetranchus urticae Koch.) and root-knot nematode (Meloidogyne incognita). Among all these pests tomato fruit borer (Helicoverpa armigera Hubner) and whitefly (Bemisa tabaci Gen.) are the most important pests.

In present studies, evaluation of IPM modules for tomato was conducted at ASPEE Agricultural Research and Development Foundation (ARDF) Farm.

Out of 20 cultivars cultivar PKM-1 was found significantly less susceptible to whiteflies while the cultivars pusa. Early Dwarf, Sun-7611, DPLT-14 and BWR-5 were found most susceptible to Bemisia tabaci Gen.

All the varieties showed distinctly different reaction against tomato fruit borer H. armigera. Among 20 cultivars screened against fruit borer the variety BT-1 was less preferred by fruit borer (1.020 larvae/ plant) whereas the variety Pusa Early Dwarf was the most preferred (2.58 larvae plant).

The percent fruit infestation was minimum in BT-1 (15.62%) while it was highest in variety Pusa Dwarf (25.29%). The variety ‘Sonali’ recommended for Konkan region was found moderately resistant with 1.377 larvae per plant and 17.13 per cent fruit infestation.

The present experiment was aimed at finding out an alternative with maximum emphasis on ecofriendly pesticides such as Agroneem, HaNPV, Bt and biocontrol agent such as Trichogramma pretiosum Riley with minimum use of chemical pesticides. Though the results have indicated superiorness of insecticidal module (M1) on reduction of larval population in H.armigera, 3 and 7 days after treatment, the module M2 consisted of Agroneem, HaNPV and Trichogramma pretiosum Riley with minimum use of chemical pesticides was at par with insecticidal control (M1 ).
