In recent years cotton growers of the Mid-South have seen an increase of early season spider mites infestations. To better understand the effects of spider mites infestations on cotton development, experimental plots were established in two planting dates (early and late) during the summer of 2013. Cotton plants were artificially infested with twospotted spider mites during cotyledon and 4th true leaf. Within each infestation time, cotton plants were exposed to mites for 3 days, 10 days, and continuously until squaring. Results will be discussed.
