Trichoderma spp. are tolerant and compatible with fungicides, biofertilizers and other bio pesticides. Integrating fungicide resistant antagonists with suitable fungicide treatment has importance in the frame work of integrated disease management. Incorporation of natural products provides a viable solution to the environmental problems caused by synthetic pesticides. Identification of these compounds and their further testing may be an effective approach to minimize the use of hazardous chemicals

A wide range of pathogens (fungi, bacteria, and viruses) affect the productivity of cucumber crop, which renders its production uneconomical. Therefore, an integrated approach was developed for the management of prevalent diseases of cucumber like damping-off and downy mildew using strategies such as growing border crop, use of reflective mulches, soil application and spray of fungicides and insecticides.

Compatibility of biocontrol agents viz., Trichoderma viride, T. harzianum and P. fluorescens were studied with four Fungicides viz., Thiram @0.3%, Carbendazim @0.1%, Captan @0.3%, fosetyl AL @0.2%, in favour of tolerance to fungicides. It was indicated that radial growth of fungal biocontrol agent Trichoderma viride was significantly inhibited (100%) with Thiram (0.3%) and Carbendazim (0.1%). Growth of T. harzianum was also 100 per cent inhibited with Carbendazim (0.1%). Whereas, both fungal biocontrol agents had recorded compatible with Fosetyl AL (0.2%), which have less (57.59% and 1.

Downy mildew caused by Pseudoperonospora cubensis is one of the most widely spread and economically important disease of cucumber. The present investigation was carried out to evaluate the efficacy of different fungicides and biocontrol agents for the management of the disease. Soil application of Trichoderma harzianum through farm yard manure (enrichment – 1kg / 100kg for 15days), seed treatment with Metalaxyl (2.0g/kg seeds).

Stem rot of rice, caused by Sclerotia oryzae is a serious threat to rice production in India. Fungicides only provide limited control of this pathogen but also have ill effects on the environment. In an attempt to develop better integrated strategies for management of this disease, a field study was conducted during rabi 2017-18 to evaluate the strategies of integration of effective fungicide Hexaconazole (0.2 %) and the bacterial antagonistic isolate P.F-4 which were effective against S. oryzae in vitro studies.

The present experiment was planned integrated management of root rot pathogen in chickpea. Occurrence of root rot disease has become a major constraint in recent years for successful and profitable cultivation of chickpea. The efficacy of Bio-agent viz. Tricoderma viride, Organic amendment viz. neem cake, Plant extract, garlic, and Fungicide, Carbendanzim applied through seed treatment and soil application were evaluated against Macrophomina phaseolina causing root rot disease of Chickpea.

The present investigation was carried out in crop season of Rabi 2013 with the wheat variety of Pusa 402. Leaf blight of wheat is an important disease of wheat in northern and eastern region of India. Use of Fungicide and bioagent can be minimized by the integrated approach towards the management of plant diseases. Treatment of foliar spray with propiconazole @500 ml/ha was found best for reduce disease intensity, higher shoot length, root length, root weight, shoot weight, number of tiller, yield/ha.
