Impact of Anthracnose on Avocado Production in Kenya (original) (raw)

Abstract

Avocado is the leading horticultural export in Kenya. In 2003, Kenya exported about 19,000 t, compared to 23 t in 1970. Most of the fruit is exported to the European markets. There are several constraints limiting production of avocado in Kenya, including limited superior varieties or planting material, poor infrastructure, poor market information, and poor tree crop management. Although several diseases infect avocado, the most important are fruit rot pathogens, such as anthracnose, cercospora, and scab. However, diseases and pests have not been important to avocado production in Kenya. Recently (2004), the constraint limiting avocado production in Kenya is anthracnose, caused by Colletotrichum gloeospoirioides. Little is known in Kenya on the impact of this disease on production and income realized by small-(<1 acre) or large-scale growers. The objectives of this research were to quantify losses attributed to anthracnose in Kenya, determine the current disease control measures,...

Nutrient concentrations of 0 to 400 ppm gave a similar pattern of decrease for P N , E, and g s . Treatment of 50 ppm had the highest P N , E, and g s . The WUE generally increased with increasing nutrient concentration.
