Five trials were conducted during 1985-1987, at Baru and Caisan (Three and two respectively) to test insecticide effectiveness at different dosages and formulations, to control corn soil insect pests. The number of healthy plants were measured 10, 20, 30 and 60 days after planting (DAP), dry grain yield was recorded at harvest. The treatments were: carbofuran 10% G (2000 g a.i./ha at planting (AP); carbofuran 10% G + clorpyrifos 4CE (2000 g a.i./ha + 1300 g a.i./ha AP); clorpyrifos 4CE (1300 g a.i/ha AP); carbofuran 4F (243.2; 120.8; 60.4 and 30.2 g a.i./ha seed treatment (ST); carbofuran 10% G + carbofuran 10% G (1000 g a.i./ha AP + 1000 g a.i./ha 30 (DAP); furathiocarb 666 SCO (243.2; 120 and 62.0 g a.i./ha, ST); furathiocarb 40 SD (238.5 g a.i./ha, ST); carbosulfan 25 STD (159 and 119 g a.i./ha ST). The seed treatment demonstrated a noticeable protective level. Yields with the lowest costs were measured on treatments with carbofuran 4F (30.2 g a.i./ha) and furathiocarb 666 SCO (120.8 g a.i./ha) at Baru; and carbofuran 4F (60.4 g a.i./ha) and furathiocarb 666 SCO (62.0 g a.i./ha) at Caisan. The main soil insect pests were ants (Solenopsis spp.) at Baru, and the white grubs complex (Phyllophaga spp. and Anomalla spp.) at Caisan. These caused the highest damage at 10 DAP.

Se determinó el número de plantas sanas a los 10, 20, 30 y 60 días después de siembra (DDS), y el rendimiento de maíz seco. Los tratamientos fueron carbofuran 10% G (2000 g i.a./ha a la siembra); carbofuran 10% G + clorpyrifos 4CE (2000 g i.a./ha + 1300 g i.a./ha a la siembra); clorpyrifos 4CE (1300 g i.a./ha a la siembra); carbofuran 4F (243.2; 120.8; 60.4 y 30.2 g i.a./ha tratamiento a la semilla, TS); carbofuran 10% G + carbofuran 10% G (1000 g i.a./ha a la siembra + 1000 g i.a./ha a 30 días después de siembra); furathiocarb 666 SCO (243.2; 120.8 y 62.0 g i.a./ha, TS); furathiocarb 40 SD (238.5 g i.a./ha, TS); carbosulfan 25 STD (159 y 119 g i.a./ha TS). De los resultados sobresalieron en el nivel de protección y rendimientos con los menores costos variables los tratamientos a la semilla: carbofuran 4F (30.2 g i.a./ha) para el área de Barú; y el carbofuran 4F (60.4 g i.a./ha) para el área de Caisán. Se determinó que la principal plaga del suelo en Barú son las hormigas (Solenopsis spp.), y en Caisán el complejo gallina ciega (Phyllophaga spp. y Anomalla spp.), las cuales inciden mayormente durante los 10 DDS.  Instituto de Innovación Agropecuaria de Panamá 1990-03-07 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo revisado por pares application/pdf http://www.revistacienciaagropecuaria.ac.pa/index.php/ciencia-agropecuaria/article/view/522 Ciencia Agropecuaria; Núm. 6 (1990); 127-142 2414-3278 0258-6452 spa http://www.revistacienciaagropecuaria.ac.pa/index.php/ciencia-agropecuaria/article/view/522/417
