Affected seedlings wither and die. Is a major disease during the rainy season. It is caused by a (or dry) tomato blight soil-borne and air borne fungus. Symptoms are brownish-black 8 angular spots with concentric circles on the leaflets. Black or (Alternaria solani) brown sunken lesions develop on stems and fruits Symptoms show as necrotic spots on leaves which enlarge Late blight (Phytophtora 9 rapidly to become water-soaked areas on leaves and fruits. infestans) Infestation leads to defoliation and fruit blotches. Rots and cankers are caused by fungi and bacteria that infect tomato stems and roots. Root and stem rot fungus is present in Rots and cankers (Phoma 10 soil and attacks roots, causing collars to rot. The bacteria that spp., Phomopsis spp.) attack plants cause blight and cankers of stems, leaves and fruits. It is the most serious disease of tomatoes. Transmitted by white Tomato yellow leave curl flies feeding on tomato leaves. Plants infected by disease are 11 virus (TYLCV) stunted and turn yellow, and leaves curl. Affected flowers and fruits drop off. Caused by a soil-borne fungus that attacks roots through small wounds (made during transplanting or resulting from nematode 12 attack). Plant wilt from lower leaves and leaves turn yellow and Wilts (Fusarium oxysporum) die; later whole plant wilts and dies. IPM Strategy for Pest Control 4.2 The integrated pest control is the adopted strategy for the fight against pests in Ghana. However, the use of the integrated combat is not widespread despite the efforts undertaken. The use of pesticides is increasing in spite of the high cost of the products relative to the financial capacity of majority of farmers. Research Institutions in have had some good results with regard to the efficient use of products, the alternatives. In actual fact, several institutes (Crops Research Institute, Faculty of Agriculture/KNUST, University of Ghana, Legon, Savannah Agricultural Research Institute (SARI) have conducted projects concerning the integrated management of pests in several operations (maize, cowpea, mangoes, lemon, rice, cucumber, cotton etc), the development of a control system for the use of pesticides for communities practicing urban related agriculture, IPM Kit development, demonstration and transfer of technology in IPM.
