IPM CRSP Goals in Kenya IPM CRSP Goals in Kenya

• Develop improved IPM technologies
• Increase household income
• Improve IPM research and education
• Increase

gender equity and involvement

• f

women in IPM decision making and program design

IPM CRSP

IPM-CRSP Emphasis IPM-CRSP Emphasis

• Multidisciplinary teams
• Multi-institutional teams
• On-farm

research & participatory research The project embraces close linkages between research, extn and farmers.

Constraints Constraints

• Lack of regional coordination and shared strategy
• Lack of an IPM research focus on higher-value

horticultural crops

• Pests (insects, diseases and weeds) priorities were

identified at a stakeholders meeting held in Nairobi

• Priority crops-tomato, passionfruit, onion, banana

Tomato Production constraints

6

Limited technical knowledge on high tunnel tomato production and grafting among the major tomato growers.

• H. tunnel production system considerations

IPM Strategies (Biotic)

Exclusion‐double doors, foot bath, clean seedlings, insect proof netting Sanitation‐Inside and

• utside (weeds, crop

residue, prunings) Scouting and monitoring‐ visual inspection, use of sticky traps Safe control of pests (whitefly bollworm, thrips, mites)

Weather and soil factors (abiotic)

Rainfall‐Affects slope of the structure Temperatures‐choice of material to use (net or plastic), shape and height

• f structure, ventilators.

Wind strength and direction‐wind breakers Soil type‐planting method, irrigation and drainage, nutrition, diseases mgt

LOW COST WOODEN‐A FRAME GOTHIC‐ ARCH

 The open frame is composed of wood, metal or plastic. The frame forms a basic “A” “gothic/arched,”

• r

“Quonset/U‐tunnel” shape. The frame may form a single or multiple, attached (adjacent) units of these shapes. These are made either using frame‐metal, wood, or PVC pipes

Effects of grafting rootstock on tomato plant vigor and yield

• Soil solarization, a non chemical technique that captures radiant

heat energy from the sun was found to control bacterial wilt in tomato grown in a high tunnel.

• Tomato grown in beds where the clear plastic sheet had been

placed for 8 weeks had no bacterial wilt incidence compared to non-solarized tomato bed in Kirinyaga, Kenya (right).

Passionfruit activities

Objectives

• To develop IPM packages for major pests of

passion fruit including Fusarium wilt, dieback, brown spot, viruses and arthropod pests (aphids, leafminers, mealybugs, thrips)

• To transfer knowledge and technology packages

to stakeholders through innovative farmer participatory approaches

Passion fruit activities at Juja, Central Kenya

Dieback disease symptom Initial and late stages of dieback

Evaluation of biocontrol agents and fungicides in control of brown spot disease

• On farm evaluation of T. asperellum, T. harzianum and Cu

in controlling brown spot on PPF and KPF12

• PPF + TA spray; PPF + TH spray; PPF +Cu spray;PPF/Control
• KPF12 +TA spray; KPF12 +TH spray; KPF12 + Cu spray;

KPF12/control

• Site; juja farm

Brown spot disease symptoms

Brown spot on leaves, fruit and stem

Virus symptoms‐ Fruit woodiness, ring spots and leaf curl

and roll, mosaics and crinkling

Validation of virus diagnostic procedure developed at Ohio State university

• Symptomatic and

asymptomatic passion fruit samples for validation of the designed primers have been collected from farms

• Uasin Gishu District
• Nakuru North
