How to manage thrips in onion crop?

31/03/2020Posted on

It is a small insect which causes the most damage to the onion crop. Both its infant and adults suck the juice by hiding it in the cheekbones of the leaves. This forms yellow-white spots on the leaves, and in the later stages, the leaves shrink. This insect is yellow in their initial stages which turns dark brown later. Its lifespan is of 8–10 days. Adults live in a dormant state on an onion field, on the grass and other plants. In winter, thrips go into tubers and act as a source of infection the next year. These pests appear in large numbers on onion tubers during March-April. They suck the juice from leaves which makes them spiral and limits the plant’s growth. Sometimes their infestation remains on the tubers even during the storage.

Preventive measures –

-For control of thrips in onion, deep ploughing should be done in summer.

-Do not use nitrogen fertilizer in excess.

–Spray Profenophos 50 E.C. @ 45 ml or lambda-cyhalothrin 4.9% c.s. @ 20 ml or spinosed @ 10 ml or fipronil 5 s.c. with 15 litres of water per acre.

Good news for farmers, government lifted the ban on onion exports

Gramophone's onion farmer

To protect the interests of farmers, the government has lifted the six-month-old ban on the export of onions on 26th February. This decision will provide farmers with a big market for their onion crop and thus they can earn more profit. There was a major need for such step as the prices are likely to fall heavily due to bumper production of rabi crops especially onion.

It should be noted that in September 2019, the government had imposed a ban on the export of onions due to the rapid increase in its prices. But the conditions have changed now and the onion rates had stabilized. Along with this, there has been a rapid growth of onions this year in the country, because of which, Food Minister Ram Vilas Paswan has announced to lift the ban on the export of onions.
