A key finding is that overnight charging currently has the lowest absolute level of CO2 emissions and a relatively low variance compared to other times of charging. This may not imply that an EV solution is categorically preferred on the … Continue reading →

The intensification experiment was implemented in an established walnut orchard at the Plant Sciences Field Facility in Davis, CA, USA . The orchard was planted in the spring of 2015 with ‘Chandler’ walnuts. The entire orchard was 0.7 ha in … Continue reading →

In California, field bindweed survives in both irrigated and dryland environments, and it grows through much of the year in annual and perennial cropping systems as well as non-crop areas like roadsides . This species causes yield loss, reduces water … Continue reading →

However, competitive suppression of native seedlings by exotics eclipsed the feedback effect, highlighting the need for weed control in the restoration process.Understanding long-term plant community dynamics has been a key challenge in ecology , made even more challenging by the … Continue reading →

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 →
