Bio pesticides are pesticides which are formed by using natural materials like plants, animals and its excreta, bacteria and minerals. Bio pesticides are often used in Integrated Pest Management(IPM) also. Conventional pesticides, on the other hand, use synthetic materials to control pests. However, due to increased awareness about the detrimental effects of conventional pesticides, the demand for bio pesticides has been steadily increasing. With the organic farming being an influential factor in the current farming setup, bio pesticides play a significant role in the entire organic inputs sector. Bio pesticides are need of the hour due to increase in pest resistance and yield. The global biopesticides market size is projected to grow at a CAGR of 14.7% from an estimated billion value of USD 4.3 billion in 2020 to reach USD 8.5 billion by 2025. Thus, the growing organic products market has made a considerable impact in the demand for bio pesticides. Against this backdrop, the present study is taken up to analyse the estimated demand of bio pesticides in India. KEY WORDS: Bio pesticides, demand

Communicating to others towards text which is as the result of discourse is everyone need. In producing text, there are some factors affected. Context which is one important influential factor needs to be analyzed. On the other hand, conversation as a media of exchanging meaning among the speakers are done in order to fulfill speaker aim. Pragmatics that learns meaning is seen as the best media to learn meaning produced by both speakers related to the context. By using interactional sociolinguistics, as a part of conversation analysis in pragmatics, this approach takes pragmatic and sociolinguistics aspects of interaction, as well as adjacency pairs, turn-taking and sequences, giving importance to the way that language is situated in particular circumstances in social life. Based on the analysis done, it maps out that interactional talk claiming common ground with vague reference as a marker of both speaker friendship.

The fundamentals of managing pests in protected structures are very similar in many respects to managing pests in field crops. But conditions within a protected structure can be modified to a certain degree to prevent, delay, or even mitigate pest issues. On the other hand, conditions that discourage one group of pests can often favor another. This 7-page fact sheet was written by Hugh A. Smith, Gary E. Vallad, and Bielinski M.

Asian citrus psyllid [ACP (Diaphorina citri)] is one of the most serious threats to the global citrus (Citrus sp.) culture, and management of ACP has depended primarily on the application of chemical insecticides. The expression of resistance mechanisms to herbivory is a key component in integrated pest management in crop production in which silicon (Si) applications can play an important role in plant–insect relationships. The objective of the current study was to evaluate the application of Si to tahiti lime (Citrus latifolia) plants under natural infestations of ACP. Two experiments were conducted using 15-month-old seedlings and 2-year-old trees, respectively. Treatments were 1) foliar Si sprays (potassium silicate) at a dose of 2 mL·L–1, 2) soil Si application at a dose of 1 kg commercial product per plant, 3) combined soil and foliar applications of Si at the doses just listed, and 4) untreated plants (control). The application of Si treatments to both seedlings and trees affected ACP oviposition, causing a reduction of 60%. Applications of Si did not affect the nutritional status (macronutrients and micronutrients) of plants in either test, except that the foliar concentration of Si tended to be greater in the soil and soil + foliar treatments than in the other treatment in both seedlings and trees. Based on these results, we suggest that Si can be added as a component of ACP integrated pest management programs.

SummaryThe sugarcane whitefly, Neomaskellia andropogonis Corbett (Homoptera: Aleyrodidae), is one of the important pests of sugarcane in Iran. The use of selective chemical insecticides helps to suppress whitefly infestations. Although several insecticides from various groups have been registered to control whiteflies, this is the first study to test the efficacy of deltamethrin, dinotefuran and spiromesifen insecticides against eggs, second instar nymphs and pupae of the sugarcane whitefly on CP69-1062 sugarcane cultivar. Five concentrations of the tested insecticides were applied in a leaf dipping bioassay under laboratory conditions. Probit analysis indicated that deltamethrin and dinotefuran with LC50 values of 50.1 and 49.5 ppm were the most toxic insecticides against eggs of N. andropogonis. Deltamethrin controlled nymphal and pupal stages more effective than the other two tested insecticides and the LC50 values were 49.7 and 5.44 ppm on nymphs and pupae, respectively. The LC50 values of dinotefuran on second instar nymphs and pupae were 564.7 and 78.7 ppm and the values were 270.9 and 18.3 ppm for spiromesifen, respectively. The results support the use of the insecticides in rotation according to their different mode of action in integrated pest management programs of the sugarcane whitefly N. andropogonis.

A look forward.

Field-based residual bioassays and residue analysis were conducted to assess the field performance and toxicity longevity of different insecticides that had previously been associated with resistance of Choristoneura rosaceana populations collected from apple and cherry orchards. In this study, 12–24 h-old larvae of apple and cherry populations were exposed to apple and cherry leaf samples, respectively, at post-application intervals and a susceptible population served as a reference of each. In the apple and cherry trials, the order of residual longevity of insecticides that effectively controlled the tested populations was as follows: bifenthrin and spinetoram (apple: 14, cherry 21-day post-application), phosmet (apple: 7, cherry 14-day post-application), chlorantraniliprole (apple: 7-day post-application), and indoxacarb and emamectin benzoate (apple: 1, cherry 7-day post-application). Compared to the susceptible population, the resistant populations resulted in a measurable loss of field performance, or “practical resistance”, for the insecticides emamectin benzoate (at 7-day post-application), chlorantraniliprole (at 21-day post-application), and indoxacarb (at all post-application intervals) in the apple trials, while in cherry trial just indoxacarb at 7-day post-application showed a reduced efficacy. In terms of long-lasting residues, only chlorantraniliprole and indoxacarb maintained measurable leaf residues over all post-application intervals while the leaf residues of the other compounds had largely degraded within the first 7 days. These findings can help fruit growers make adjustments to their spray/re-application intervals and optimally utilize important chemical tools in their integrated pest management programs.
