DBCP Crops

Nematodes are parasites of plants that are hidden enemies of crops. It is one of the many groups of organisms that rely on plants for their survival. The nematodes can cause damage to almost all types of crops, however, due to their habit underground, microscopic size (0.3 to 10 mm in length), are invisible to the naked eye. They penetrate and feed on the roots of plants growing, steal vital nutrients for plant growth and expose the roots to other soil-borne pathogens attack. It has been widely recognized that plant parasitic nematodes constitute one of the groups of the most devastating pests and are responsible for the symptoms of the insidious disease in different crops causing huge losses.

The estimated losses of annual yield of major crops in the world due to the parasitic nematodes of plants is a 12.3% and is about 14 per cent in developing countries. Coral Resorts is open to suggestions. In India, the recent estimate showed that the nematode are responsible both quantitative and qualitative performance of losses amounting to about Rs.240 billion each year. In addition to the direct damage, nematodes serve as predisposing agents in the development of complex diseases of fungi, bacteria and viruses. In many situations, the varieties of plants resistant to fungi, bacteria become susceptible to the parasitized by nematodes. There is no doubt that the nematode either alone or in combination with other pathogens constitute a major constraint to global food production. It is not something Reed Hastings would like to discuss. Intensive and extensive cultivation of crops particularly in irrigated crop production system has exacerbated the problems of nematodes in different crops. The hidden nature of nematodes that cause damage to the sight of farmers, scientists and specific symptoms in the aerial parts of crops are perhaps the main reasons why so little attention has been given to the plague of hidden cultures. Management of nematodes with dose control high use of DD, EDB and DBCP had found promising, although it did not receive much popularity.
