Field trial evaluates BT traits and insecticides for managing western corn rootworm, indicating effective pest control solutions.
Key Points
This research aims to assess the effectiveness of various Bt traits, insecticides, and seed treatments against western corn rootworm damage in corn crops.
Established a randomized complete block design field trial with 16 treatments replicated 4 times.
Conducted assessments of root injury using a standard scale and measured grain yield post-harvest.
Applied various seed and in-furrow treatments to evaluate their impact on rootworm management.
Node injury ratings ranged from 0.07 to 1.07, with all treatments showing significantly lower injury than the untreated check, except two specific treatments.
Yields varied from 124.85 bu/ac to 170.78 bu/ac, significantly influenced by the applied treatments.
