  1. THRIPS MANAGEMENT PRACTICES IN FRENCH BEAN PRODUCTION AND EFFICACY OF INTEGRATED PESTICIDE APPLICATION REGIEMES IN EMBU EAST Benard Ouma Ogala-University of Nairobi Supervisors Dr. James Muthomi -University of Nairobi Prof. John Nderitu-Mount Kenya University Dr.Faith Torotich -University of Nairobi

  2. 1.Introduction 1.Inputs-Not affordable 2.EU regulation-Barriers to trade MRL-10% sample per consignment 150000-200000 Ksh per shipment 3. Private standards e.g. Global GAP: Smallholder farmers have problems in meeting the costs

  3. 2. Objectives Broad To develop an integrated thrips management regime suitable for small scale growers. Specific • To determine pest management strategies used by small scale French bean farmers in Embu • To evaluate the efficacy of integrating biological, synthetic and botanical pesticides in management of thrips.

  4. 3. Determination of current pest control practices 3.1Sampling procedure • Sample size-70 farmers • Multistage sampling technique • Farmers randomly selected from the list of French bean farmers • Structured questionnaire 3.2Data collected • Challenges to French beans production • Farmers knowledge of pests and their management practices. • French bean varieties grown, harvesting and post harvest • Marketing channels and certification status of farmers

  5. 3.3: ResultsFigure 3.1: Constraints to French beans production

  6. Figure 3.2:Important pest as perceived by farmers

  7. Figure 3.3:Methods of control

  8. Table 3.1:Record keeping and storage of pesticides

  9. Table 3.2:Marketing, marketing channels and certification status of farmers in Embu East district

  10. 4. Effects of integrating biological, synthetic and botanical pesticides on pod quality and yield of French beans 4.1Design-RCBD, 4 replicates 4.2 Treatments • chemical plus biological pesticides - at 50% flowerinng, 8 days later, 16 days • chemical plus botanical pesticides - at 50% flowerinng, 8 days later, 16 days • conventional pesticide - at 50% flowerinng, 8 days later, 16 days • botanical plus biological - at 50% flowerinng, 8 days later, 16 days • Biological pesticide - at 50% flowerinng, 8 days later, 16 days • Control plots - no pesticide application. 4.3 Data collected • Growth parameters • Thrips population • Pod quality • Pod yield

  11. 4.4 ResultsTable 4.1:Effects of pesticide spray regiemes on thrips population- F.spp

  12. Table 4.2:Effects of pesticide spray regiemes on thrips population-Megalulothrips and larvae

  13. Table 4.3:Effects of pesticide spray regiemes on pod quality of French beans
