Components of soil suppressiveness against Heterodera schachtii
Heterodera schachtii populations were introduced into nematode-suppressive and conducive field plots and were monitored for 2550 degree-days (DD). At 1200 DD, H. schachtii population densitiesExpand

Interaction of Fusarium solani f. sp. glycines and Heterodera glycines in Sudden Death Syndrome of Soybean.
ABSTRACT Sudden death syndrome (SDS) of soybean is caused by the soilborne Fusarium solani f. sp. glycines (synonym F. virguliforme). In a sequential approach, two multifactor factorial-designExpand

Biological Suppression and Natural Population Decline of Heterodera schachtii in a California Field.
ABSTRACT Soil suppressiveness to Heterodera schachtii was demonstrated in a field at the research station of the University of California, Riverside. In two field trials planted to Swiss chard (BetaExpand

Transfer of Biological Soil Suppressiveness Against Heterodera schachtii.
ABSTRACT Heterodera schachtii-suppressive soil at a rate of either 1 or 10% (dry wt/wt) transferred suppressiveness against the beet cyst nematode to fumigated field plots when mixed into the upperExpand

Vertical Distribution of Rotylenchulus reniformis in Cotton Fields.
The possible impact of Rotylenchulus reniformis below plow depth was evaluated by measuring the vertical distribution of R. reniformis and soil texture in 20 symptomatic fields on 17 farms across sixExpand

Soil suppressiveness to Heterodera schachtii under different cropping sequences
Heterodera schachtii population densities were monitored in a H. schachtii -suppressive soil cropped in screenhouse experiments for two consecutive seasons with wheat, susceptible or resistantExpand

Effects of Inoculations with Mycorrhizal Fungi of Soilless Potting Mixes During Transplant Production on Watermelon Growth and Early Fruit Yield
Watermelon, Citrullus lanatus (Thunb.) Matsum. & Nakai, crops are contin- uously exposed to soilborne diseases. In many areas of the United States, greenhouse- raised watermelon seedlings areExpand

Contributions of Fusarium virguliforme and Heterodera glycines to the Disease Complex of Sudden Death Syndrome of Soybean
Background Sudden death syndrome (SDS) of soybean caused by Fusarium virguliforme spreads and reduces soybean yields through the North Central region of the U.S. The fungal pathogen and HeteroderaExpand

Depth Distribution of Rotylenchulus reniformis Under Different Tillage and Crop Sequence Systems.
ABSTRACT The population density of the reniform nematode, Rotylenchulus reniformis, was monitored at depths of 0 to 30, 30 to 60, 60 to 90, and 90 to 120 cm in a tillage and crop sequence trial inExpand
