Simple grazing models with two herbivores are used to assess the effects of pasture pests on stability and productivity of continously-growing pastures. Algebraic and graphical methods are also presented for estimating losses from pasture pests at different stocking rates directly, from data on productivity/stocking rate relationships. Pests are considered as competing grazing herbivores and de...

Wheat is one of the major cereal crops with annual global production over 600 MT from about 200 M hectares (FAO 2012). The cultivation of wheat started about 10,000 years ago as part of the Neolithic revolution which state a transition from hunting and gathering of food to settle agriculture. Earlier cultivated forms of wheat were diploid (einkorn) and tetraploid (emmer) with known initial orig...

Current GM crops are thus far the almost exclusive domain of herbicide and insect resistance traits. The Bt toxins used for insect control have a narrow specificity against lepidopteran and coleopteran pests only. Yet, aphids and thrips are highly important pests worldwide, causing severe direct losses and transmitting devastating viruses such as Tomato Spotted Wilt Virus (TSWV). So far, few us...

Pest detection and identification of diseases in agricultural crops is essential to ensure good productivity. The productivity of plants will reduce due to diseases and presence of pests. Image processing can be used to identify the pests and thereby can reduce the use of pesticides. Image processing involves capturing the image and applying various preprocessing techniques and detect the pest ...

the adoption of integrated pest management (ipm) strategy by farmers of bathinda cotton belt of punjab, india resulted in reduction of insecticidal applications. there was 3-4 times reduction in insecticidal applications in ipm villages (4.86-5.33) over the non-ipm villages (15.16-18.12). a general trend of reduced insecticidal applications of both conventional as well as new insecticides, in i...

ozone is a powerful oxidant capable of killing insects and microorganisms and has been used in the food processing industry in the gaseous and aqueous states. in a laboratory study, the susceptibility of immature stages of an important stored-product pest, the indian meal moth, plodia interpunctella hubner to ozonated water was investigated. ozone was applied in aqueous form at four concentrati...
