A new trend for controlling tomato leaf-miner, Tuta absoluta (Meyrick).

Abstract

The tomato leafminer, Tuta absoluta causing a huge economic problem in Egypt. The effects of Agree 50% WG, Avaunt 15% EC, Excellent 1.9% EC, Titan, Castor aqueous extract, K.Z oil, and Alboleum oil against the tomato leaf- miner, T. absoluta (Meyrick) were evaluated. Avaunt 15% EC is succeeded in T. absoluta management since it is initially reduced of the infestation were 80.42 and 78.29, respectively. Meanwhile, the total mean of reduction after 1, 3, 10, and 15 days were 79.20, and 79.26 respectively, for the 1st and 2nd spray. While the initial reduction of Excellent 1.9% EC, Agree 50% WG, Castor aqueous extract, Titan, K.Z oil, and Alboleum oil were 80.68, 80.38, 79.70, 71.62, 72.44, and 70.68, respectively for 1st spray. Furthermore, the initial reduction of Excellent 1.9% EC, Agree 50% WG, Castor aqueous extract, Titan, K.Z oil, and Alboleum oil were 80.76, 77.23, 77.30, 72.58, 70.00, and 69.98 for 2nd spray, respectively. The total mean of reduction for Avaunt 15% EC, Excellent 1.9% EC, Agree 50% WG, Castor aqueous extract, Titan, K.Z oil, and Alboleum oil were 79.20, 74.71, 74.59, 72.72, 70.35, 69.15, and 64.96 for 1st spray, respectively. Although, the total mean of reduction for Avaunt 15% EC, Excellent 1.9% EC, Agree 50% WG, Castor aqueous extract, Titan, K.Z oil, and Alboleum oil was 79.26, 74.73, 73.88, 73.40, 68.49, 67.47, and 62.27 for 2nd spray, respectively.
