Interpretive Summary:

Technical Abstract: Pre-plant no-tillage cotton production systems can produce greater net returns than conventional tillage cotton; however, producers are concerned that crop residue on the soil surface will increase insect pest problems. The objective of this study was to determine the effect of conventional tillage and pre-plant no-tillage on silverleaf whitefly populations and boll weevil, bollworm/tobacco budworm plant damage in irrigated cotton during a three-year period. Boll weevil and bollworm percent damage of squares and bolls and silverleaf whitefly populations in the pre-plant no-tillage system were less than or equal to the conventional tillage for each of the three years of the study, indicating that corn or cotton crop residue on the soil surface does not increase boll weevil damage to squares or bolls or whitefly populations in irrigated cotton in south Texas.
