Basic biology and rearing methods were determined for Timandra griseata Peterson (Lepidoptera: Geometridae) and Homorosoma chinensis Wagner (Coleoptera: Curculionidae), two potential biological control agents of mile-a-minute weed (Polygonum perfoliatum L., Polygonaceae). Both species also were tested for their ability to feed and develop on crop plants in the family Polygonaceae.T. griseatadef...

A texture–based weed classification method was developed. The method consisted of a low–level Gabor wavelets–based feature extraction algorithm and a high–level neural network–based pattern recognition algorithm. This classification method was specifically developed to explore the feasibility of classifying weed images into broadleaf and grass categories for spatially selective weed control. In...

BACKGROUND Type 1 Diabetes Mellitus (T1DM) is the most common endocrine-metabolic disease in children. It is associated with vascular and neuropathic complications, and may also affect growth and development. OBJECTIVE To correlate the metabolic control and disease duration with growth and puberty in patients with T1DM followed in a Pediatric Endocrinology Outpatient Clinic. SUBJECTS AND ME...

In order to determine aqueous extract effects of cool-season turfgrass mixture clipping on germination and seedling growth of four weed species, laboratory and outdoor pot experiments were done at the experimental laboratory and greenhouse of the Doroud Parks and Landscape Organization, located in Doroud, Lorestan, Iran. The first factor was the concentration of sport turfgrass clipping extract...

Introduction of glyphosate resistance into crops through genetic modification has revolutionized crop protection. Glyphosate is a broad-spectrum herbicide with favorable environmental characteristics and effective broad-spectrum weed control that has greatly improved crop protection efficiency. However, in less than a decade, the utility of this technology is threatened by the occurrence of gly...

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...

Abstract XtendFlex® technology from Bayer allows growers to apply glyphosate, glufosinate, and dicamba POST cotton. Since the evolution spread of glyphosate-resistant weed species, early applications with several modes action have become common. However, crop injury potential these warrants further examination. Field studies were conducted 2015 2017 at two locations in Mississippi evaluate cott...

Ten insect species were introduced to control five weeds on the island of Mauritius from 1914 to1982. Eight of these (80%) became established. The biocontrol programs against Opuntia vulgaris, O. tuna and Cordia curassavica were completely successful, with all three target plants now not considered as weeds, and requiring no management other than the ongoing, self-sustaining biological control....
