humidity favours the spread of the disease and severity. The fungus has the ability to overwinter in plant debris and remains in the field for long time [...] dark brown margins. The spots may enlarge to 1 cm to more and later coalesce. The spots dry up results in shot-hole appearance to the leaves. Severely infected [...] Veni GoKlean at the rate 1.25 to 1.5 ml per litre of water at 12-15 days intervals as preventative spray and or after recognition of the disease symptoms

Brown root rot, corky root rot

rot. Damage symptoms The first signs of this disease, are poorly looking plants in localized areas of the greenhouse or field. The affected plants may wilt [...] gradually break off. The corky areas often occur as horizontal bands on the roots with lengthwise cracks. No discoloration is present in the xylem tissues which [...] survives in the soil and in buried tomato roots as microsclerotia. The microsclerotia germinate and produce mycelium that in turn infect the roots of tomato

Black rot of carrots

spores surviving in the soil are the main source of infection. Especially wheat and barley reduce the number of surviving conidia in the soil. Use resistant [...] General The only known stage in all Alternaria species is the asexual stage. Conidia and mycelium overwinter in the soil and on crop residues and cause [...] seed-transferred carrot disease. The seeds are the main source of primary infection and this may lead to death of seedlings. From the primary infection of leaves

No fruit formation if the infection occurs early. Disease cycle Powdery growth of the fungus consists of mycelium, conidiophores and [...] favourable conditions for the pathogen severity.

The spots on leaves and pods are round, on the stems they are more elongated. The lesions are light brown, sunken and [...] surrounded by a dark brown to red-brown border. The first infection is often on the primary leaves. The fungus is seed borne and thus also causes post-

The specks grow into brown spots that look like scab. These spots may be surrounded by a halo. In pepper, the spots on the leaves are also [...] also round and small to start with and slightly raised from the leaf surface. They occur on the abaxial (underside of) leaf surfaces and may enlarge into

The fungus produces ascospores and conidia, but their role in the epidemic has not yet been established [...] spot of strawberry and fruit rot reported mainly from Brazil. The genus is quite complex, so the taxonomy may change. Pestalotiopsis clavispora is also called
