Petioles are so short that leaves seem to be glued to the stem. They become soft and glabrous and somewhat yellow in colour. Affected plants do not bear any flowers or fruits if infection is in early stages of plant growth. However, in cases of late season infections fruits may remain small, become hard and unfit for consumption or marketing.

Both the pre-emergence and post-emergence damping-off symptoms are seen in diseased state. The germinating seeds are infected by fungi at the initial stages. The infection later spreads to hypocotyls basal stem and developing roots. The post-emergence damping off phase is characterized by infection of the young, juvenile tissues of the collar at the ground level.

It is a well documented fact that increased dependence on agrochemicals including fertilizers has led to several ill effects on the environment and human.
Where does eggplant come from?
The brinjal, eggplant or Aubergine (French name) has originated in the Indian sub-continent and China ( Thompson and Kelly, 1957; Purewal, 1957; Martin and Rhodes, 1979 ). Brinjal is an important vegetable crop of the Far East, Bangladesh, India, China and the Philippines. The name brinjal is popular in Indian subcontinents and is derived from Arabic and Sanskrit whereas the name eggplant has been derived from the shape of the fruit of some varieties which are white and resemble in shape to chicken eggs. It is also called aubergine (French word) in Europe. According to the 1994 FAO Production Year book, the world eggplant production areas were 556,000 ha and the total production was 8,979,000 mt. Asia has the largest eggplant production which comprises more than 90% of the world production area and 87% of the world production. (The data did not include India and Bangladesh). Gill and Tomar (1991) reported 299,770 ha of eggplant production area in India and 29,150 ha in Bangladesh in 1992-1993, bringing the Asian total close to 830,000 ha. The brinjal is of much importance in the warm areas of Far East, being grown extensively in India, Bangladesh, Pakistan, China and the Philippines. India is considered to be the centre of origin of cultivated brinjal, from where it spread to the other parts of the world ( Choudhury and Malda, 1968) it is also popular in Egypt, France, Italy and United States. In India, it is one of the most common, popular and principal vegetable crops grown throughout the country except higher altitudes.
