  1. POSITIVE PRODUCTS FOR CONTROL OF INSECT PESTS , DISEASES AND WEEDS IN RICE(Dr RK Wanjogu and CM Kambo) Presentation during the NIB / Collaborators research findings Workshop, Kenya School of Monetary Studies, 3rd to 4th July, 2014.

  2. Introduction • Rice (Oryzae sativa) is the third most important food crop in Kenya after maize and wheat • National rice consumption is estimated at 400,000 metric tonnes • Annual production range of 45,000 to 80,000 metric tonnes • Low production is caused mainly by poor natural resource management • And continuous monoculture leading to accumulation of, weeds, diseases and insect pests

  3. PADDY FIELD

  4. Objectives • To evaluate the efficacy of 6 selected Insecticides against rice pests • To evaluate the efficacy of 4 selected Fungicides against weeds paddy fields • To evaluate the efficacy of 5 selected Herbicides against weeds paddy fields

  5. Justification • Target pests: Insect pests, diseases and weeds • If uncontrolled, may cause upto 100% yield losses • Evaluation of pest control products should be a continuous processes • For effective pesticide resistance management insecticide screening is necessary

  6. Materials and methods • Field experiments : Conducted at MIAD Research Centre between 2012 and 2014 • Rice variety, Basmati 370 was planted at a spacing of 15 cm x20 cm • Plot size – 5m by 1 m : In RCBD with 4 replicates • Treatments: 5 including, Local check & untreated control

  7. Example: East trap 4G

  8. Efficacy of East trap 4G against Rice pests

  9. Recommendation • East trap 4G at the rate of 15 kg to 20 kg per hectare effectively controlled the shoot borers, root borers, leaf folders and gall midges in rice fields. • In addition, significantly more tillers were recorded in plots treated with East trap 4G at 20 kg ha-1 and Cyclone 505 EC 1.0 L ha-1 (Local check) as compared to the untreated control plots • East trap 4G at 20 kg ha-1 recorded significantly taller plants as compared to the local check and untreated control plots • Two season results: East trap4G at 15-20 kg ha-1 may be recommended for the control of shoot borers, root borers, leaf folders and gall midges in rice fields.
