Boll Weevil facts are interesting.

Are you interested in knowing about a pest that constantly ruins crops especially cotton productions? We present to the nefarious Boll Weevil.

These insects infect the cotton boll of cotton bolls which effectively means the seed of the cotton plant. When the cotton boll or the cotton bolls are affected, it leads to the destruction of the crop as well as diminishing the cotton-producing capability of the fields. A diminished cotton-producing field means there is a disruption in the production of the cotton industry. Like a domino effect, the cotton industry, as well as the textile industry, can suffer huge losses if these insects are not kept under a check and thus the eradication program is an absolute necessity for these pests.

As a measure for Boll Weevil infestation control, stern measures for the Boll Weevil eradication program are now taking place. Owing to this Boll Weevil eradication, states of the US are now slowly becoming free from this pest. Read on to learn more!
