An experiment was conducted to evaluate the effectiveness of plant materials against yellow mite (Polyphagotarsonemus latus) on jute (Corchorus olitorius) cv. 0–9897 in both greenhouse and field condition at BJRI during the period from March to October 2016. In greenhouse premises, the highest mortality (69.39, 67.77, 63.86, 62.43 and 61.47%) was recorded in extract of neem seed kernel @ 1:20, mehogony seed, pithraj seed, turmeric powder and green neem leaf, respectively.

Four botanicals viz., mahogany oil, mahogany seed extract, tobacco leaf extract, neem seed kernel extract along with one synthetic chemical, cypermethrin were tested for their efficacies against H. armigera. The lowest fruit infestation, both by number and weight, was observed in neem seed kernel extract (27.15%, 22.29%) treated plot which was statistically similar to tobacco leaf extract (27.71%, 23.31%) treated plot and cypermethrin (28.87%, 25.44%) treated fruits.

Abstract:
Crude extracts of the seed kernels of the neem tree (Azadirachta indica) are widely used as plant protection products. The active ingredient (a.i.) of these extracts is azadirachtin A (aza A). aza A is a phytochemical (botanical) complex secondary metabolite which, with it is multiple toxic effects on insects, protects the plant against predation. Aza A is present in only low concentration in neem oil, but makes up 20-50% in the NSKEs extracted by polar solvents from the kernels. However, when used as foliar sprays it is rapidly destroyed by sunlight, and might be more effective if it is used

ABSTRACT Volumetric image data of rocks often need sophisticated image processing steps in any rock physics and petrophysics workflow. While the segmentation is highly dependent on the quality of data, a trade-off between resolution and field of view is inevitable. This work attempts to resolve this using multiple-point statistics that have long been used for generating synthetic images, though mostly applied to sandstone rocks where the heterogeneity is significantly less than that of carbonates. These algorithms work by sequentially populating a grid to emulate the observed image. However, f
