Node Counts as an Indicator for Termination of Insecticide Treatments in Cotton

J.L. Bernhardt, J.R. Phillips, and N.P. Tugwell


 
ABSTRACT

These data indicate that node counts are a viable method to assess a decline in bloom production and boll set, a decline in set bolls producing harvestable bolls, a point in the cumulative percent lint yield after which less than 2% of the final yield will be set, and a point where micronaire approaches the lowest values of the season. Data indicate that an average node count value of 4 ± 0.2 was the point at which less than 2% of yield remained to be set on plants for early planted cotton, and less than 1% of yield for the average planting date in Arkansas. Node counts could be a valuable part of a management program through the reduction in the number of late season insecticide applications without a major loss to yield.
