Overhead systems are the dominant irrigation technology in many parts of the world, but they are not widely used in California even though they have higher water application efficiency than furrow irrigation systems and lower labor requirements than drip systems. With water and labor perennial concerns in California, the suitability of overhead systems merits consideration. From 2008 through 2013, in studies near Five Points, California, we evaluated overhead irrigation for wheat, corn, cotton, tomato, onion and broccoli as an alternative to furrow and drip irrigation. With the exception of tomato, equal or increased yields were achieved with overhead irrigation. Many variables are involved in the choice of an irrigation system, but our results suggest that, with more research to support best management practices, overhead irrigation may be useful to a wider set of California farmers than currently use it. © 2016, University of California.

California's 300,000 acre pistachio industry consists of over 90% Pistacia vera. Cultivars with different harvest timing would relieve the pressure on processing facilities. A recently identified cultivar, 'Pete I' harvests earlier, but is producing unacceptably high percentages of early season aborted nuts, which abscise, as well as partially filled and blank nuts. Both overload the hullers and float tanks. Field observations suggested insect pressure and/or fungal infestation. In an insect exclusion study, flower buds were both covered by insect-impermeable mesh and left uncovered on the 'Pete I' trees for the season until harvest. The resulting clusters showed no significant difference in the final percentage of aborted nuts between the bagged and unbagged samples. Laboratory plating of early-and mid-season nuts for fungal pathogens detected none beyond background levels. Therefore, high percentages of blanking and partially filled nuts in the 'Pete I' pistachio cultivar were not due to either insect or fungal pressures. Other possibilities are pollen or ovule incompatibility, or self-thinning through embryo abortion.

Cotton production in the San Joaquin Valley has traditionally relied heavily on tillage for its presumed benefits to plant establishment, yields and insect management. Research in the 1960s and 1970s demonstrated the potential of precision or zone tillage, which foreshadowed the introduction of a variety of minimum tillage implements in the early 1990s. During a 3-year comparison study from 2001 to 2003, cotton yields in strip tillage plots matched or exceeded yields of standard tillage plots in all 3 years. In a 12-year study from 1999 to 2011, tillage costs were lowered an average of $70 per acre in 2011 dollars using no-tillage compared to standard tillage while achieving statistically comparable yields, provided that adequate crop stands were achieved. If bottom-line profitability can be maintained, conservation tillage may become increasingly attractive to cotton producers in the San Joaquin Valley.

Objective: The incidence of Kaposis sarcoma (KS) decreased dramatically after the introduction of highly active antiretroviraltherapy (HAART). This study determined the ongoing incidence of and mortality from KS in HIV-infected adults from 1998-2012in Fresno County, California. The role of virologic control and immune reconstitution was assessed.Methods: Incident caseswere identified from the state Electronic HIV/AIDS Reporting System (EHARS), the California Cancer Registry, and hospitalrecords of the county HIV treatment center.Results: From 1998-2012, the average incidence of KS was 0.51 cases per 100,000person-years. Of the 66 cases of KS there were 20 deaths, with 85% of the mortality occurring in the first 12 months. Amongpatients on HAART achieving HIV RNA <400 copies/uL, but with a <50 cell/uL increase in CD4 count there was no improvementin mortality.Conclusions: The incidence of KS remains stable since 1998 with a 12-month mortality of 30%. © The Author(s) 2013.

Aims: To determine incidence and levels of ochratoxin A (OTA) in California raisins and to isolate and characterize OTA-producing fungi from California raisin vineyard populations. Methods and Results: Forty raisin clusters sampled from four California vineyards in the San Joaquin Valley were analysed for OTA content using immunoaffinity and HPLC methods. OTA was detected in 93% of the samples, at levels from 0·06 to 11·4ngg-1. From these raisin samples, a total of 400 strains of Aspergillus were isolated and analysed for OTA production. Twelve isolates (3%), from five raisin samples, produced OTA. These isolates were identified as Aspergillus carbonarius, based on morphological characteristics and multilocus sequence analysis. Levels of OTA produced by these isolates on raisin agar ranged from 0·9 to 15μgg-1. Conclusions: OTA is a common contaminant of raisin vineyards, but average levels are much lower than EU regulatory limits for dried fruit. The primary species responsible for OTA contamination in California raisins is A. carbonarius. Significance and Impact of the Study: This study illustrates that low-level OTA contamination of raisins occurs in California and that ecological studies of A. carbonarius within the Aspergillus section Nigri population on raisins are warranted to monitor ochratoxigenic potential of the crop.

The evolution of resistance by pests can reduce the efficacy of transgenic crops that produce insecticidal toxins from Bacillus thuringiensis (Bt). However, fitness costs may act to delay pest resistance to Bt toxins. Meta-analysis of results from four previous studies revealed that the entomopathogenic nematode Steinernema riobrave (Rhabditida: Steinernematidae) imposed a 20% fitness cost for larvae of pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae), that were homozygous for resistance to Bt toxin Cry1Ac, but no significant fitness cost was detected for heterozygotes. We conducted greenhouse and laboratory selection experiments to determine whether S. riobrave would delay the evolution of pink bollworm resistance to Cry1Ac. We mimicked the high dose/refuge scenario in the greenhouse with Bt cotton (Gossypium hirsutum L.) plants and refuges of non-Bt cotton plants, and in the laboratory with diet containing Cry1Ac and refuges of untreated diet. In both experiments, half of the replicates were exposed to S. riobrave and half were not. In the greenhouse, S. riobrave did not delay resistance. In the laboratory, S. riobrave delayed resistance after two generations but not after four generations. Simulation modeling showed that an initial resistance allele frequency >0.015 and population bottlenecks can diminish or eliminate the resistance-delaying effects of fitness costs. We hypothesize that these factors may have reduced the resistance-delaying effects of S. riobrave in the selection experiments. The experimental and modeling results suggest that entomopathogenic nematodes could slow the evolution of pest resistance to Bt crops, but only under some conditions. © 2012 Entomological Society of America.

Monsanto's Roundup weedkiller atomizers are displayed for sale at a garden shop at Bonneuil-Sur-Marne near Paris, France, June 16, 2015. The seed and agrochemicals company said it filed the suit against the state's Office of Environmental Health Hazard Assessment (OEHHA) and the agency's acting director, Lauren Zeise, in California state court, according to the filing seen by Reuters. California law requires the state to keep a list of cancer-causing chemicals to inform residents of their risks. OEHHA said in September that it planned to add glyphosate to the list after the World Health Organization's International Agency for Research on Cancer (IARC) classified it as a probable human carcinogen last March. Monsanto has disputed assessment, citing decades of studies deeming glyphosate safe, including a 2007 study by OEHHA that concluded the chemical was unlikely to cause cancer. "The IARC classification of glyphosate is inconsistent with the findings of regulatory bodies in the United States and around the world, and it is not a sound basis for any regulatory action," said Phil Miller, Monsanto's vice president of regulatory affairs. Monsanto's lawsuit argues that listing glyphosate under Proposition 65, as the state's law is known, based on IARC's classification cedes regulatory authority to an "unelected, undemocratic, unaccountable, and foreign body" that is not subject to oversight by any state or federal entity. Monsanto argues that the lack of oversight violates the company's right to procedural due process under California and U.S. law. A listing would also require Monsanto and others offering products containing glyphosate to provide a "clear and reasonable warning" to consumers that the chemical is known to cause cancer, damaging Monsanto's reputation and violating its First Amendment rights, the company said. OEHHA did not comment, as it had not seen the lawsuit. The case is Monsanto Company v. Office of Environmental Health Hazard Assessment, et al, case number 16-CECG-00183 in the Superior Court of the State of California, County of Fresno. Roundup is used by farmers around the world, generating Monsanto $4.8 billion in fiscal 2015 revenue. Genetically modified seeds designed to tolerate glyphosate are immensely popular among corn and soybean growers. But questions from environmentalists and other critics about the safety of the herbicide have dogged Monsanto for years. Since IARC's classification last year, Monsanto has been named in numerous lawsuits accusing the company of knowing of the dangers of glyphosate for decades.
