The combined application of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are commonly used malaria interventions that target indoor Anopheles vectors. Recent studies on the effects of house screening (HS) and LLINs have demonstrated a reduction in indoor vector densities and malaria when the interventions are combined.

The parapheromone traps are excellent tool in reducing the population of fruit flies in snake gourd ecosystem. In farmer‟s situation, due to lack of awareness, availability and knowledge on its mechanism of trapping all paves way to move towards the spraying of insecticides. Considering these key limitations, this present investigation was framed to develop locally available, cost effective trap designs for the efficient eco-friendly management of fruit flies in snake gourd ecosystem.

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.

Cyantraniliprole 10% OD at 90 g a.i.ha-1 was significantly effective when sprayed twice at 15 days interval, minimized the sucking pests population and increased cotton kapas yield. Cyantraniliprole 10% OD treatments at 90, 180 and 320 g a.i. ha-1 concentrations had not caused any phytotoxic effects like injury to leaf tip, leaf surface, wilting, vein clearing, necrosis, epinasty and hyponasty. Cyantraniliprole 10% (w/v) OD showed the least effect against the spiders.

Field investigation carried out to evaluate performance of newer insecticidal treatments on natural enemies and yield contributing factors in sorghum at sorghum research farm, Mahatma Phule Krishi Vidyapeeth, Rahuri during rabi season of 2013-14. The observation recorded after two spray revealed that significant differences among all treatments. The result on natural enemies revealed that the seed treatment of imidacloprid 48 % FS 10ml/kg and spray of azadirachtin 3000 ppm were less toxic and most safer treatment to predatory Coccinellids and Crossopalpus sp. population.

A field experiment was conducted at Agricultural College Farm, Bapatla to test the efficacy of some recommended insecticides and fungicides as a tank mix application. Two insecticidal treatments (chlorantraniliprole @ 0.3 ml l-1 and chlorpyriphos @ 2.5 ml l-1 ) and two fungicidal treatments (tricyclazole @ 0.6 g l-1 and isoprothiolane @ 1.5 ml l-1 ) with an untreated control were replicated thrice in a simple randomized block design. The results showed that all the insecticide and fungicide treatments alone and in combination were found superior over untreated check.

Seven insecticides tested against fruit borer, Helicoverpa armigera of tomato, Solanum lycopersicum under field condition. The efficiency of insecticides was similar effective after both sprays as indoxacarb 14.5SC > novaluron 10EC > spinosad45 EC > rynaxypyr 20SC > nske 5% > nimbicidine 5% > neemoil 1% against reduction in fruit infestation. The maximum increased seed yield (45.00 q/ha) recorded from Indoxacarb 14.5 SC treated plots. The maximum cost benefit was return from Indoxacarb 14.5 SC treatment, Rs. 16 after per rupee investment.

Field experiment was conducted during 2011 and 2012 to evaluate the efficacy of chemical insecticides and plant botanicals for the management of Yellow Mosaic Virus of Mungbean transmitted by the vector whitefly (Bemisia tabaci). It was noted that disease incidence could not be escaped however, the percentage of incidence were different from each other over control plot. Among the five plant origin products with different doses tested for spraying, Neem @ 0.2% showed lowest incidence (10.49%) and severity (9.58%). Among three insecticides the significant lowest incidence (8.

The study was conducted to evaluate the two sprayers for bioefficacy was carried out in cotton (Bt) and pigeonpea at the farmer’s field, Raichur during 2017-18. The insecticide used [dinotefuran (osheen)] was solution with a recommended dose 150 g 500 l-1 . The chemical used for spraying the pigeonpea crop was emamectin benzoate (ASTRA). The chemical was mixed with water at a proportion of 100 g 500 l-1 . The insects were reduced from pre counting as the number of days increased after the spraying. The populations of aphids were 10, after 5 days reduced to 2.5 numbers.
