Pheromone trap@1 for 400 sq.m. + weekly release of 50,000 to 60,000 Trichogramma chilonis + two sprays of  BT @1ml/L at 10 days interval at peak flowering.

IIHR has   developed  a biological control strategy for management of Helopeltis antonii infesting Guava by using  fungal pathogen Beauveria bassiana.  Weekly spraying of this bio- pesticide @ 1x109 spores/ml with suitable adjuvants  recorded significant reduction in the pest damage that was comparable with the chemical pesticides.

Application / Use:

This is a bio-pesticide useful for the management of fungal pathogens such as Fusarium species and Phytophtora species as well as nematodes.

Specific Benefits:

This is an eco-friendly component of management. It is useful for the management of nematodes and fungal pathogens

Description:

The IPM package given below will take care of fruit borer, leaf miner, mite and insect vector.

Nursery:

• Raise Marigold (Tall African variety golden age bearing yellow and orange flowers) nursery 15-20 days before tomato nursery
• One week after germination of seeds, spray the seedlings with (imidacloprid 200 SL @ 0.3 ml/l or thiomethoxam 25 WP @ 0.3 g/l)

Before transplanting:

Application / Use:

The soaps prepared from neem oil and pongamia oils respectively and are in concentrate from. These have to be diluted with water (10 g/litre) and sprayed on plants to control insect pests just like insecticides. The soap sprays can be used as a substitute for synthetic insecticides and can be used as a component of IPM in many vegetable crops and as organic input.

Specific Benefits:

Organic input and production of pesticide free vegetables.

Unit Cost:

• Sanitation: Sanitation is to be maintained for eliminating the sources of seed borer infestation.  Collection and destruction of the off season stray mature sapota fruits after main harvest till November will bring down the  pest incidence.
• Use of light traps: Erecting light traps in the field during cropping season will attract adult moths and will minimize the incidence.
