Objective: In this study the efficacy of two agent of this biological control agent of corn stem borer in corn fields compared with common synthetic insecticides Endosolfan to find a suitable alternative for chemical control of pests in corn fields. Methods: In order to evaluate the efficiency of biocontrol agents of corn stem borer ,Ostrinia nubilalis, experiment was conducted in a ra...

Xanthium strumarium, commonly referred to as "cocklebur," rarely causes poisoning in cattle. When mature, this robust, annual weed bears numerous oval, brownish, spiny burs. Only the seeds in the burs and young seedlings (cotyledonary leaves) contain the toxic principle, carboxyatractyloside. In the Frankfort district of the Free State Province of South Africa, a herd of 150 Bonsmara cows were ...

Development of an autonomous weeding machine requires a vision system capable of detecting and locating the position of the crop. It is important for the vision system to be able to recognize the accurate position of the crop stem to be protected during weeding. Several shape features of corn plants and common weed species in the location were extracted by means of morphological operations. Eff...

3. Verruca plantaris.?These are horny, corn-like growths usually on the soles of the feet but sometimes on the palms of the hands. They do not project much externally but their inward projection into the corium may be considerable. They are often mistaken for corns but differ from the latter by the possession of blood vessels. 4. Verruca accuminata.?This type occurs mostly in the folds about th...

Lactating dairy cow diets with more than 24% starch (DM basis) are common, but recent high corn prices have fueled a desire to feed lower-starch diets. The potential for using digestible neutral detergent fiber or pectin from byproduct feeds or sugars to partially replace starch from corn grain in diets fed to lactating dairy cows was reviewed. Potential modifying effects of corn silage, starch...

We describe four recently developed panel data estimators for unbalanced and nested data, a common problem for economic and experimental data. We estimate a western corn rootworm damage function with each estimator, including separate parameters for random effects from year, location, and experimental errors. We then use each estimator to assess the cost of the western corn rootworm soybean var...

in order to study the effect of intercropping of corn with bean and bitter vetch and farmyard manure (fym) on corn nutrition, a factorial experiment was carried out on the basis of randomized complete blocks design with three replications. the factors were types of intercropping systems at levels of sole bean, bean+corn, sole bitter vetch, bitter vetch+corn, sole corn, and fym at levels of 0, 3...
