Soldiers of the 42nd Infantry Battalion found a marijuana plantation of 40,000 square metres, about 4 hectares, near the village of Arriba in the municipality of Badiraguato, Sinaloa, on 25 November 2009.[1] The troops were carrying out ground reconnaissance near the village when they came on the plantation.[1]

The plants were about 1.2 metres tall and grew at a stated density of 15 plants per square metre, which the Defence Ministry’s own figures put at some 600,000 plants over the 40,000 square metres.[1] Soldiers destroyed the plantation by manual work and burned it where it was found.[1] No one was arrested in the operation.[1]

The Secretariat of National Defence said the find was made under the Permanent Campaign Against Drug Trafficking and the enforcement of the Federal Firearms and Explosives Act.[1]
