Treatment of Lycopersicon esculentum and Lagenaria siceraria plants, with phytoproteins, isolated from roots of Boerhaavia diffusa and leaves of Clerodendrum aculeatum, mixed separately with bio enhancer, could significantly prevent the infection and spread of tomato mosaic/tomato leaf curl virus. It was revealed that the potential of CA phytoprotein mediated induction of resistance was increased, in plants treated with CA phytoprotein along with bio enhancer M9 and M3. The CA phytoprotein mixed together with M9 was found to be more efficacious in protecting crops against viruses than Clerodendrum aculeatum alone. On the other hand, potential of Boerhaavia diffusa phytoprotein was also enhanced by the addition of bio enhancers M9 and M3, in inducing systemic resistance in Lycopersicon esculentum and Lagenaria siceraria plants, against natural infection of tomato mosaic/tomato leaf curl or cucumber mosaic virus respectively. Higher degree of modified systemic resistance was induced by BD phytoprotein, mixed with bio enhancers as compared to BD phytoprotein alone. However, BD phytoprotein in combination with M9 was found to be more effective than BD alone or BD with M3.
