Introduction
• Tomato (Lycopersicon esculentum) is
among the most important vegetable
grown in Kenya, ranked eighth in
terms of value among the
agricultural foods produced in the
country, (FAOSTAT, 2010), where it is
used in salads, or cooked as a
vegetable or processed into tomato
paste, sauce and puree, ( Bio-vision,
2005)
• There are two broad categories that are
grown in Kenya: For fresh market varieties which
includes; money maker, mar globe,
marmade, elgon dume, onyx, eden and
beauty
while for processing are; rome vf, cal J
and MP2, (KARI, 2005).
• Cal J variety being popular for fresh market
for its good quality in shelf life, colour and
disease resistance against early blight.
Objectives
General objective:
• To increase the tomato yields realized thereby
contributing to food and nutritional security
and improved livelihoods of farmers by
generating income from the sale of the
produce.
Specific objectives:
• To evaluate the most effective fungicides in
the management of early blight of tomato.
• To evaluate the impact of the disease on the
yield and quality of tomato.
Problem statement
• Tomato productivity in Kenya 12ton/ha,
compared to country like Zimbabwe
where production of up to 100tons/ha
is being realized. (Bio-vision 2005).
Justification
• Early blight caused by Alternaria solani
is the most important disease of
tomatoes causing yield losses up to 80%
(Singh, 1985; Mathur and Shekhawat,
1986; Chandravanshi et al., 1994).
Materials
• Fungicides being used are:
Antracol®WP 70 – it is a broad spectrum
protective fungicide, active ingredient propineb
700g/kg. Application rate of 50g per 20 liters of
water.
Rodomil® 68 WG – it is a systemic fungicide with
metalaxyl-M 40g/kg + Mancozeb 640g/kg.
Application rate of 50g/20 liters of water.
Daconil® 720 SC – It is a broad spectrum contact
fungicide with the active ingredient Chlorothalonil
720g/lt.
Application rate of 40ml/20liters of
water.
Methodology
 The field experiment will be laid out in Randomized
Complete Block Design (RCBD) with 4 treatments and 3
replications for each treatment during the month of
December 2012 and April 2013 at College of
Agriculture and Veterinary Science (CAVS) field station.
 Cal J variety of seedlings will be raised in nursery bed
and 28 days old seedlings will be transplanted into the
field with 60 cm inter and 60 cm intra row spacing in
plots measuring 1.8 x 1.2 m.
 All other cultural and pest control practices will be
followed as recommended in package of practices
(Anon 1998).

Data analysis
• Data will be subjected to analysis of variance
using Genstat.
• The least significant difference will be used to
compare the differences among treatments
means.
• The correlation coefficient among the different
parameters will be analyzed using statistical
package for social science (SPSS), statistical
software.
• Analysis of data collected using variance (ANOVA)
will be carried out using the SPSS.
