Wild fungus gardens contained similar peptaibols, indicating their ecological relevance, consistent with peptaibol-producing Trichoderma being an opportunistic pathogen of T. septentrionalis fungus gardens . In our laboratory experiments, two of the Trichoderma fractions with the highest abundance of peptaibols, fractions D and E, … Continue reading →

There are several methods to make pollen grains functionally deficient and thereby reduce seed set . The most commonly used is ionizing irradiation with X-rays or gamma rays due to their ease of use, effective penetration, consistent results, and minimal disposal … Continue reading →

Chlopyralid is especially effective for control of legumes and composites such as Canada thistle , and yellow starthistle. Because it does not control many common broad leaf weeds such as mustards, it must be tank-mixed for complete control of the wide range … Continue reading →

Few California soils in sunflower growing areas have shown yield limiting K deficiencies; sandy soils are the most likely to show K fertilizer responses.Sulfur deficiency, though rarely observed in sunflowers, is characterized by slow growth and overall uniform light green color … Continue reading →

These two weevils are the most widely used biological control agents of water hyacinth, Eichhornia crassipes , a floating aquatic plant native to South America. Classical biological control of water hyacinth has been implemented across the globe, with some introductions … Continue reading →

Twenty-seven weedy rice plants were chosen for genotyping along with 12 accessions of temperate japonica varieties that are cultivated in California. Leaf tissue from the outdoor grown plants was excised and desiccated for shipment to Clemson University for DNA extraction. … Continue reading →

Restriction digestion of the target region-specific PCR product from lines 1, 2, 5 and 11 revealed that lines 1 and 5 were fully resistant to BsrI digestion, whereas line 11 showed partial digestion. However, line 2 showed complete digestion of the … Continue reading →

Recombination was only detected in O. rufipogon, so the longest nonrecombining blocks were only utilized in the comparisons including O. rufipogon. Each comparison was run in M-mode with wide value cutoffs for all parameters to determine where posterior probability distributions ranged. After … Continue reading →

As required for layer stacks, the imagery was resampled to a single scale using cubic convolution. The increase in pixel size brought the grain of the images and that of the field evaluations of vegetation composition to a similar scale, and … Continue reading →

When dealing with fast maturing crops, the grower can prevent weeds from dispersing seeds . Since weeds adapt to continuous use of the same tools, implementations of other integrated management plans are crucial .Using more than one management strategy increases … Continue reading →
