Experiments controlling corn ear di bailey wallace (2 risultati)

Paperback. Condizione: New. Print on Demand. This book presents insights into methods of controlling pests that infest sweet corn ears destined for shipment to markets during the winter months. Historically, sweet corn production has been a summertime activity in the northern half of the United States due to the voracious appetite of the corn earworm. The author presents experimental results for the individual and combined effectiveness of various clipping, covering, and insecticidal treatments against three major pests of sweet corn in Puerto Rico: corn earworm, fall armyworm, and corn-silk fly. Strengths and weaknesses of various methods and combinations for managing each pest are analyzed to aid corn producers in developing appropriate pest management strategies. The author ultimately advocates for treating ears with a mixture of pyrethrum extract and mineral oil, supplemented by manually removing the very ends of the dried silks and husks, as the most efficient method for controlling all three pests.
