The Department of Agriculture in Thailand is warning farmers in Chachoengsao Province about a severe outbreak of four-legged coconut mites, a pest that can cause significant damage to coconut production. The mites, which are not visible to the naked eye, cause deep grooves in the fruit, leading to small, atrophied, and falling coconuts. The mites can reduce yield by up to 70%. Due to the location of the mites within the fruit poles, spraying is not an effective control method. The Department of Agriculture is surveying the damage and providing training to farmers on prevention and control measures. Farmers with questions can contact the Mites and Spider Research Group.
