Tricogreen: to fight wilting

November 6, 2017 - Article blog News Research

Bawang merah/shallot is no stranger in our cuisines. It is present in almost every dish. Shallot production can take place in temperate zones to the tropics. Indonesia, a tropical country, is the largest producer of this commodity in Southeast Asia.

According to the official report from the Ministry  of Agriculture (29/08/17), in  2016 the area of harvest in the country reached up to 149.6 thousand ha, with the production of 1.45 million metric tons. The latter represents a 22.5% increase from the previous year. The target for 2017 is to increase by 17.7% from 2016. But this optimistic target is not without fear of crop failure.

One of the most significant diseases in shallot production is wilting caused by the fungus Fusarium oxysporum. This fungus attacks the base of the bulb and destroys root formation. The early indicator of infestation is the yellowing as well as twisting of leaves. The weakness or absence of root causes plants to dislodge easily from the ground. Another indicator is the white spots on the base of the bulb. Further cutting into the bulb will expose decaying layers that originate from the base and spread in all directions.

To combat this dreadful pest, Indmira produces Tricogreen. This biofungicide is made from trichoderm fumgus that is known to be very effective in controlling the growth of pathogenic fungi in the soil. This product is in a powder with greenish white color and eco-friendly, and as such, it is harmless to humans, animals, and the environment.

The applications of Tricogreen are as follow:

  1. Seeding:
