Cladode and Fruit Rots of Prickly Pear (Opuntia ficus-indica L. Mill.) in Egypt
|

Abstract: Abstract:
Cladode and fruit rots of prickly pear cactus (Opuntia ficus-indica L. Mill.) were observed in some commercial orchards located at the major producing areas of four governorates in Egypt. Symptoms initially begin as brown to dark spots on the affected cladode and fruit tissues, rot and discoloration of internal tissues with exudates oozing from the affected tissues. The survey proved that the disease was found in the inspected orchards at various degrees according to the locality. Alternaria alternata; Botryodiplodia theobromae and Fusarium solani were consistently isolated from infected tissues and were pathogenic to both cladodes and fruits of prickly pear. This is the first report of the later two fungi on prickly pear in Egypt. The study on the effect of different fungicides on the growth of the three pathogens revealed that Topsin M70, Bellis and Tecto were the best treatments against the fungi. The same fungicides were used to control cladode rot disease on detached cladodes. Tecto, Bellis and Topsin M70 were the most effective to control the disease.
Key words: Cladode rot, Opuntia ficus-indica and prickly pear cactus.
