Abstract
Smallholder famers in Sub-Saharan Africa (SSA) have been encouraged
to produce horticultural crops as an agricultural and rural development strategy to
enhance incomes and improve household nutrition. In Uganda, intensifi ed production
of marketed vegetable crops has led to changing agricultural practices, including
crop and input-intensifi cation, a changing set of pests, and increased use and
reliance on synthetic pesticides to manage these pests. Beginning in 2002, the IPM
CRSP team in Uganda implemented a participatory IPM program with smallholder
farmers to develop and disseminate alternative pest management strategies for managing
priority pests and reducing pesticide usage on tomato. The major pest constraints
addressed were late blight, bacterial wilt, viruses, bollworm, aphids, thrips
and white fl ies. Baseline farmer surveys indicated that farmers were spraying a variety
of pesticides 12–24 times per growing season. The component technologies
developed into a package and disseminated to farmers included a bacteria wilt resistant
tomato variety MT56, mulching, staking, and a minimum spray schedule of 3–4
pesticide sprays per season. Impact assessments indicated that yields were 40 %
higher when the package was used and reduced production costs (by reducing the
number of sprays) that led to higher net revenues for IPM-practicing tomato farmers.
Use of MT56 and mulching led to a 21 % reduction in production costs and led
to an internal rate of return of 250 % if adopted. Use of tomato variety MT56 reduced
production cost by 21 % with a Benefi t: Cost ratio of 770. Other IPM technologies
developed included grafting using bacterial wilt resistant rootstocks; seedling production
using low tunnel systems for pest/vector exclusion; and good nursery management
practices.
