“Battling Potato Pests: Protecting Your Potatoes from Common Culprits”

Greasy Cutworm/ Black cut worm:  

The young larvae of these pests eat the outer layer of the potato plant leaves, while the older larvae, which are active during the night, cut the stems of young plants. Additionally, they can damage the tubers by partially consuming them.

Chemical Management 

Drench Chlorpyriphos 50% EC @ 1-2 ltr/Acre or Chlorpyriphos 50% + Cypermetrin 5% EC @ 1-2 ltr/Acre.

Potato tuber moth: 

The potato tuber moth is a pest that affects both potato fields and storage areas. The larvae of this moth cause wilting by digging tunnels in the leaves, stem, and tubers of potato plants. They create galleries near the eyes of the tubers. These tunnels make the tubers unsuitable for use as seed or for human consumption. Additionally, infested tubers are prone to rotting due to microbial infection. The extent of damage to stored tubers can vary from 20% to 85%.

Chemical Management

Spray Broflanilide 300G/L SC @ 17-25 ml/Acre  or  Tetraniliprole 200 g/L @ 0.5 ml/ltr Water or Cartap hydrochloride 75% SP @ 1 gm/ltr Water.

White grubs: 

Symptoms of feeding damage occur on roots and tubers. Grubs also feed voraciously during night time.

Chemical Management 

Drench Chlorpyriphos 50% EC @ 1-2 ltr/Acre or Chlorpyriphos 50% + Cypermetrin 5% EC @ 1-2 ltr/Acre

Tobacco Caterpillar: 

The young tobacco caterpillar larvae gather together and scrape the leaves, while the older larvae spread out and may eat all of the leaves, which can cause stunted plant growth.

Chemical Management Spray Pyridalyl 10% EC @ 1.5-2 ml/ltr Water or Novaluron 5.25% + Indoxacarb 4.5% w/w SC @ 1.5-2 ml/ltr Water.
