Scientists are rediscovering the value of the unique combination of five products of the cow, especially as pesticide
plant disease management has today become more independent of chemical treatment as its hazardous ramifications have been recognised. Scientists involved in plant protection are concentrating, therefore, on alternate methods to avoid the usage of chemicals. Any method or innovation, however small its impact, should be considered a step forward in this direction. In this regard, our work at the University of Agricultural Sciences ( uas ), Bangalore, on the management of a fungal pathogen of tomato crop is significant.
The soil-borne pathogen, Fusarium Oxysporum lycopersici, causes diseases in the tomato seedling and wilt in the adult plants. The disease is prevalent the world over and the damage caused ranges from 10 to 100 per cent, depending on the environment. Among the many products tested by us, panchagavya, an organic formulation has been found to be promising.In Sanskrit, panchagavya means a combination of five products procured from the cow. It is an ancient ritua-listic practice prescribed in Hindu scriptures to administer panchagavya to human beings under many conditions of ill health, convalescence and as a spiritual purifying agent. This preparation is also recommended as a cure for epilepsy, jaundice and fever as per the ancient system of medicine in India.
Tests to control the Fusarium wilt disease of tomato with various formulations show that panchagavya is the most effective
|Treatment||Plant diease index (PDI)||Mean shoot length (cm)||Mean root length (cm)||shoot dry weight (grams)||Root dry weight (grams)||Fruit yield (tonnes hectare)||Cost benefit ratio|
|Neem cake (nc)**||25||95||25.5||35.4||2.6||11.6||1:1.4|
|NOTE:*-Carbendazim at 0.1 percent; **-neem cake @ 250gm per sq m; PDI was computered by adopting 0/4 scale to cover all the symptomology criteria, giveing weightage proportionate to the degree of symptom contributing towards the yield of tomato|
