Activated carbon for improving diuron selectivity in beans

Creator:: Romero M., Carlos Eduardo
Abstract:: Activated carbon is effective in protecting beans from herbicide injury. In a field study, diuron [3-(3, 4- dichlorophenyl)- 1- 1- dimethyl urea], linuron [3- ( 3, 4- dichloropheny1)- 1- methoxy- 1- naethylurea], fluometuron [1, 1-dimethyl- 3-(α , α, α -trifluoro- m-toly1) urea], and metobromuron [3, (2- bromophenyI)- 1- 1- rnethoxy-...

Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

Creator:: Asquith, Adam
Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...

Girdling and shading effects on inflorescence necrosis and rachis composition of pinot noir grapevine

Creator:: Ibacache, Antonio E.
Abstract:: There are several grape disorders that reduce fruit set. One, millerandage, is from poor fertilization to produce "hen and chicken" or small seedless berries; while another, Coulure, is the failure of grape flowers to develop into berries. A third one, inflorescence necrosis (INec), is a disorder that should be in...

The control of colonial bentgrass in Kentucky bluegrass turf

Creator:: McLoughlin, John Walter
Abstract:: Herbicides were tested for the selective control of bentgrass in Kentucky bluegrass turf under three levels of competition. Best control in zero competition was obtained with a winter treatment of bromacil at two pounds per acre. Under circumferential and direct competition, best control was obtained with a summer and fall...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

Persistence and accumulation of clopyralid (3,6-dichloropicolinic acid) in soil

Creator:: Tanphiphat, Karin
Abstract:: Field studies were started at Hyslop Farm, Corvallis, Oregon in 1984 to determine the soil persistence of the herbicide clopyralid (3,6-dichloropicolinic acid) under cropping situations. The herbicide was sprayed on bare soil at the proposed use rate of 0.14 kg/ha in the spring and on the same plots at a...

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:: Maxwell, Bruce D.
Abstract:: Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...
