Sandy soils and lower rainfall averages usually need lower planting rates and heavier, clay soils and higher rainfall typically have higher seeding rates to obtain maximum yields. Field research has been conducted in fields in Calhoun, Refugio and Victoria Counties revealing different results. … Read More →

Both of these insecticides were found to be effective at controlling sugarcane aphids when applied to populations below 350 per… Read More →
