Insecticide Seed Treatments for Snap Beans
The most damaging insect pests are those that attack the pods and result in either damage or contamination of the processed product. The European corn borer (ECB) and to a lesser extent the corn earworm (CEW) are the major pod feeding pests with damage primarily from 2 generation ECB and late flights of CEW in August/September. Damage from both species occurs from flowering to harvest, creating...
متن کاملStomatal Diffusion Resistance of Snap Beans. II. Effect of Light.
The effect of light on the stomatal resistance of abaxial and adaxial leaf surfaces of snap beans (Phaseolus vulgaris L.) was studied in the growth chamber and in the field. The adaxial stomata required more light to open than the abaxial stomata; the abaxial stomatal apertures were still about 50% open at 1% full sunlight and light-induced closure was never observed under daytime field conditi...
متن کاملBiological control of weeds.
Classical biological control, i.e. the introduction and release of exotic insects, mites, or pathogens to give permanent control, is the predominant method in weed biocontrol. Inundative releases of predators and integrated pest management are less widely used. The United States, Australia, South Africa, Canada, and New Zealand use biocontrol the most. Weeds in natural ecosystems are increasing...
متن کاملSelective Control of Weeds Explained
IN August GOLFDOM I discussed the pros and cons of ammonium sulphate as a weed-control agent, while the importance of proper fertilization and management of turf were stressed in the September number from the weed control angle. While it is vital that the greenkeeper be thoroughly versed in both the theory and practice of the above phases of turf maintenance, nevertheless, in themselves, they d...
متن کاملInteractions between Population Density of the Colorado Potato Beetle, Leptinotarsa decemlineata, and Herbicide Rate for Suppression of Solanaceous Weeds
The presence of volunteer potato Solanum tuberosum L., cutleaf nightshade, S. triflorum N., and hairy nightshade, S. physalifolium Rusby (Solanales: Solanaceae), throughout potato crop rotations can diminish the effectiveness of crop rotations designed to control disease and pest problems associated with growing potatoes. In greenhouse bioassays, larvae of the Colorado potato beetle, Leptinotar...
