Hyperspectral radiometry for the detection and discrimination of damage caused by sucking pests of cotton
Use of remote sensing techniques for detection of crop stress due to pests and diseases is based on the assumption that stresses induced by them interfere with photosynthesis and physical structure of the plant, affect absorption of light energy and thus alter the reflectance spectrum of plants. Field experiments were conducted to detect and estimate damage caused by sucking pests in cotton (cv...
متن کاملTemporal Downscaling of Crop Coefficient and Crop Water Requirement from Growing Stage to Substage Scales
Crop water requirement is essential for agricultural water management, which is usually available for crop growing stages. However, crop water requirement values of monthly or weekly scales are more useful for water management. A method was proposed to downscale crop coefficient and water requirement from growing stage to substage scales, which is based on the interpolation of accumulated crop ...
متن کاملDevelopment of Transgenic Cotton Lines Expressing Allium sativum Agglutinin (ASAL) for Enhanced Resistance against Major Sap-Sucking Pests
Mannose-specific Allium sativum leaf agglutinin encoding gene (ASAL) and herbicide tolerance gene (BAR) were introduced into an elite cotton inbred line (NC-601) employing Agrobacterium-mediated genetic transformation. Cotton transformants were produced from the phosphinothricin (PPT)-resistant shoots obtained after co-cultivation of mature embryos with the Agrobacterium strain EHA105 harbourin...
متن کاملNovel Genes for Control and Deterrence of Sucking Insect Pests
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...
