“…Spraying of NPV on trap crops leaving cotton efficiently checked the population of H. armigera. The effective control of larvae on okra with NPV is in conformity with observations made by Praveen [33] . The ineffectiveness of HaNPV on cotton particularly on variety MCU 5 is in accordance with the report by Rabindra et al [34] .…”

Insecticide resistance in Helicoverpa armigera (Hubner) is a major threat to cotton production in India. The virus infection was found to increase the susceptibility of H. armigera to the insecticides. But, use of Nuclear Polyhedrosis Virus (NPV) on a larger scale and on cotton due to leaf alkalinity poses certain practical problems. Hence, studies were carried out to assess the effects of push-pull strategy with trap crops, neem and NPV in cotton for the management of insecticide resistant H. armigera. Field experiments were conducted on cotton (MCU5) with trap crops (okra and pigeonpea) and neem was used to diversify the pests to trap crops whereby the control of these pests was assessed with the application of NPV. The preference of H. armigera was towards okra and pigeonpea as a trap crop compared to cotton. Application of NSKE on cotton diversified the H. armigera towards untreated okra and pigeonpea. Push-pull strategy with the conjunctive use of trap crops, restricted application of NSKE on cotton leaving trap crops and restricted application of NPV on trap crops was highly effective in reducing the incidence of H. armigera and damage to fruiting bodies, boll, locule and inter locule basis over cotton sole crop (untreated check). The percent recovery of NPV infected larvae varied from 37.5-47.5, 32.8-39.2 and 14.2-20.2% on okra, pigeon pea and cotton respectively. The synthetic pyrethroids resistance in field survived H. armigera at the end of the season was reduced from 87.5-93.1% to 76.4-84.3%.

“…Similarly, the causal agents for blight and mildew (Fontem and Schippers, 2004) and a range of viruses (Letts et al, 2009), misdirection of federal funds, equipment, and effort affect disease pressure. Aphids were the most recurrent insect pest on vegetable crops (Kekeunou et al, 2006;Praveen and Dhandapani, 2002). Most insect pests are vectors of disease organisms (Meyer, 2003).…”

“…Control methods currently available under commercial conditions include the use of repeated applications of elemental sulphur (Kimati et al 1980) and other fungicides (Kimati et al 1997). However, as okra is known to be harvested every two days, the dependence on chemical fungicides will result in several ecological problems and resistance development against these fungicides (Parveen and Dhandapani 2002).…”

This study was carried out to evaluate the culture filtrates of certain bio-agents (Epicoccum nigrum, Epicoccum minitans, Epicoccum sp., Trichoderma harzianum, Trichoderma viride and Bacillus pumilus) alone and mixed with penconazole against powdery mildew in okra. The results showed that the culture filtrate of E. nigrum induced the highest efficacy against powdery mildew relative to other treatments in both tested seasons. Moreover, culture filtrate of E. nigrum mixed with the tested fungicide gave higher efficiency against powdery mildew than use of the fungicide alone. The efficacy of the tested culture filtrates against powdery mildew due to the presence of different antifungal compounds identified by (GC-MS) analysis. This study suggests the ability of using the culture filtrates of the tested bio-agents as alternative of fungicides to control powdery mildew in okra. Furthermore, the results implied the possibility to minimise the use of fungicides by mixing with the microbial culture filtrates.
