The total seed weight was recorded, and we calculated the total seed production by weighing and averaging five groups of 100 seeds. A t-test was used to compare the differences in inflorescence growth and seed production for treatments using massive, irradiated pollen or non-irradiated pollen against the results from open pollination. This analysis was conducted […]

Summers and Stapleton have shown that tomatoes grown over reflective mulches averaged approximately 7 percent virus-infected plants, while plants grown over bare soil averaged in excess of 50 percent infection with the same viruses. This approach is currently the only viable means of managing virus disease in these production systems. Growers are cautioned to use only […]

In addition to diseases, the cause of some disorders of sunflower appears to be varietal and physiological, with no causal diseases yet identified. In one malady observed, the female lines do not drop their heads after pollination. No management recommendations exist for this disorder given that it appears to be varietal and physiological. Foamy head rot […]

Although we sampled populations from Uruguay, we sampled them from the Uruguay River, in‐between Argentina and Uruguay, and speculate that the sample is likely genetically similar to those weevils in Santa Fe, Argentina. Thus, rather than due to multiple introductions, the higher allelic richness in Florida, Texas, and California, USA, may have been due to […]

Weedy rice emerging in cultivated rice populations could be explained by the quick loss of a few domestication alleles in regions of the genome that experienced relaxation of selective pressure. Based on an evolutionary dynamic described in [75], the evolutionary genetic dynamics we observe here could be those of deep divergence of non-endemic wild species […]

Tetflupyrolimet treatments had complete or near complete control of Echinochloa spp. by 14 DAT, but by 56 DAT, complete control was observed in all treatments regardless of tetflupyrolimet application timing. The grower standard treatment had near complete control of bearded sprangletop at 14 DAT, which later increased to complete control by 56 DAT. Treatments including […]

Glyphosate was suggested to cause inhibition of photosynthetic CO2 assimilation as well as a decrease in intermediates of the photosynthetic carbon reduction cycle. Shikimic acid, one of the main products in the EPSPS pathway, is a precursor of pigments, defense compounds, lignin and other important molecules in plants. Interestingly, glyphosate injury was also found to be […]

California’s grasslands have been dominated by naturalized exotic forage grasses for 250– 300 years, but nonetheless serve as quintessential examples of “working landscapes” that both support rich biodiversity and provide essential rangeland feed for California’s livestock industry. However, the more recent invasion of two noxious weedy grasses—Elymus caput-medusae and Aegilops triuncialis—into the naturalized forage grass-dominated […]

This distribution is to be optimized according to the size and shape of the area in which nutrients and light are provided to plant to obtain the maximum possible yield. These factors are controlled by the spacing between crop rows and the spacing of plants/seeds in a row. For many crops, row spacing is determined […]

As more effective herbicides have become available, the need for cultivation has decreased. Over the past two decades, many growers have successfully eliminated cultivation, reducing equipment and labor costs, moisture loss, root damage, and subsequent weed flushes. However, eliminating cultivation can lead to more dependence on herbicides, which may hasten the development of herbicide-resistant weeds.Field […]
