How to choose effective pesticide for tomato?

Tomato is mainly affected by Fruit borer, aphid, whitefly, leaf miner, thrips, nematode, mite, Diamond back moth, caterpillar, and beetle.

Here we share a table which can help you select pesticide based on its effect.

We have classified pesticides in five types based on their site of action Viz.

• Nerve and Muscle
• Respiration
• Midgut
• Growth and
• unknown-nonspecific.

If you have once tried pesticide with action on nerve and muscle, next time you should use pesticide which is acting on respiration or midgut or growth. Pesticides with unknown or non-specific action are mostly used as preventive sprays. 

 

Here is an example: 

if you are looking for control of Fruit borer on Tomato using a pesticide that affects nerve and muscle, you have a choice of following pesticides

1. CARBARYL 50% WP
2. CHLORANTRANILIPROLE 18.5% SC
