Overview
Major tomato pests in Uganda include early and late blights (Alternaria solani and Phytophthora infestans), bacterial wilt (Ralstonia solanacearum), aphids, thrips, mites, and African bollworms (Helicoverpa armigera). Bacterial wilt, which is soil-borne, has no chemical control available in Uganda. The IPM CRSP tomato program carried out on-farm trials to test 3 selected tomato introductions from the Asian Vegetable Research and Development Center (AVRDC) in Taiwan versus 2 older varieties for resistance to bacterial wilt. All 5 test materials showed resistance to bacterial wilt (98.6 – 100%), and were only severely infected by late blight in a few cases. Late blight infection ranged between 15-57.5%.
Objectives
To test newly introduced tomato lines for resistance to bacterial wilt, late blight and major insect pests, and yield potential under Ugandan conditions.
Outcomes
Coming soon
