Infested soybeans

Garlicky soybeans are soybeans that contain five or more green garlic bulblets or an equivalent quantity of dry or pardy dry bulblets in a 1.0-kg portion. Infested soybeans are soybeans that are infested with live weevils or other insects injurious to stored grain. Purple mottled or stained soybeans are soybeans that are discolored with pink or purple seed coats, dirt or a dirt-like substance, or pokeberry stains, as determined on a portion of 400 g with the use of an FGIS Interpretive Line Slide or Print (FGIS, 2004). 

This application was made between 0700 and 0830 a.m. in cool (air temp., 10 0 clear and windless weather. Both granular and emulsion formulations were incorporated to the 7.5cm depth with a disc cultivator within 15 minutes of application. A second cultivation to the same depth, but at right angles to the first, was completed within 2-3 hours. On May 20th both plots were spring-tooth harrowed for seed-bed preparation for soybean planting on the same day. The only subsequent soil disturbance was a row cultivation in late June to control a severe infestation of quack-grass control of broadleaf weeds was essentially complete with the trifluralin. 

Stark et o/. and Miller et reported that oxidant (ozone) injury to ponderosa pine predisposed the trees to later invasion by pine bark beeides. The beetles increase the rate of decline and may be the final cause of tree mortality (see Chapter 12). It is possible that oxidant stress in other parts of the country contributes to insect infestation in forest areas. Weber (personal communication) has shown that ozone and mixtures of ozone with sulfur dioxide (0.25 ppm, 4 h/day) can decrease the population of four nematodes associated with soybean. These... 

The inheritance of pubescence type (23) and the morphology of pubescence in soybean. Glycine max, have been studied, and densely pubescent plants were found to be the most vigorous (24). Growth differences were associated with E. fabae infestations. 

Oxyfluorfen is applied as a preemergence herbicide in soybeans, cotton, tomatoes, tobacco and green pepper at a rate of 0.2-0.4 kg active ingredient/ha. Grassy weeds are not well controlled by oxyfluorfen, but in the case of heavy grass weed infestation it can be tank—mixed with thiocarbamates, dinitroanilines, chloroacetamides, dalapon and paraquat. Oxyfluorfen is also recommended in tree fruits, vineyards and in conifer nurseries as an early postemergence treatment. 

The most important tactic for producers when operating under the threat of rust is scouting and being aware of infestation levels nationally, regionally, and locally. Numerous Web sources, sentinel plots, and weather forecasting models were assembled to help soybean producers manage the risks associated with rust. 

LOX activity was substantially increased in wounded and to a lesser extent in mite infested leaves (Fig. 3). Increased LOX was also found in the second, unwounded trifoliate of soybean plants, whose first trifoliates had been wounded (Fig. 3) indicating that LOX activity can be induced by translocatable factors. This induction of LOX activity was also seen in steady state levels of LOX protein as determined by immunoblots of SDS gels (data not shown). Preliminary evidence indicates that LOX poly A RNA levels are also increased. This wound induction of LOX may be related to possible roles in wound responses and/or pest resistance.
