    Abstract Gray mold disease or Botrytis rot, caused by *Botrytis cinerea*, it is well known for significant economic losses in vineyards worldwide, in both yield and quality. Management of gray mold it is traditionally based on fungicide treatments and cultural practices. Fungicide programmes specifically target critical periods during the growing season: late-bloom, bunch closure, veraison and preharvest. However, controlling *Botrytis cinerea* is still a challenge, because the pathogen is able to rapidly develop resistance. Also, more stringent regulations governing fungicide residues have severely restricted chemical control options in conventionally managed vineyards, particularly during the preharvest period. The objective of our study was to assess the potential of an integrated program to reduce Botrytis rot, involving fungicides and biological control agents (BCAs). Two experimental bioproducts were tested: Trichopulvin Td85 25 PU (*Trichoderma koningii* Td85 strain) and Saccharopulvin 25 PU (*Saccharomyces cerevisiae* L30b yeast strain). The efficacy of the proposed integrated program was assessed based on disease incidence and disease severity in field trials, conducted in Tohani vineyards. This integrated strategy that combines fungicides and bioproducts could offer the option to reduce the number of fungicide treatments, thus minimizing the chemical residues, and manage fungicide resistance development.

    Abstract We report a search for cosmic-ray boosted dark matter with protons using the 0.37  megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity of the Galactic Center. No such excess is observed, and limits are calculated for two reference models of dark matter with either a constant interaction cross section or through a scalar mediator. This is the first experimental search for boosted dark matter with hadrons using directional information. The results present the most stringent limits on cosmic-ray boosted dark matter and exclude the dark matter-nucleon elastic scattering cross section between 10^{-33}cm^{2} and 10^{-27}cm^{2} for dark matter mass from 1  MeV/c^{2} to 300  MeV/c^{2}.

    Abstract In order to improve Super-Kamiokande's neutron detection efficiency and to thereby increase its sensitivity to the diffuse supernova neutrino background flux, 13 tons of Gd2(SO4)3*8H2O(gadolinium sulfate octahydrate) was dissolved into the detector's otherwise ultrapure water from July 14 to August 17, 2020, marking the start of the SK-Gd phase of operations. During the loading, water was continuously recirculated at a rate of 60 m3/h, extracting water from the top of the detector and mixing it with concentrated Gd2(SO4)3*8H2O solution to create a 0.02% solution of the Gd compound before injecting it into the bottom of the detector. A clear boundary between the Gd-loaded and pure water was maintained through the loading, enabling monitoring of the loading itself and the spatial uniformity of the Gd concentration over the 35 days it took to reach the top of the detector.During the subsequent commissioning the recirculation rate was increased to 120 m3/h, resulting in a constant and uniform distribution of Gd throughout the detector and water transparency equivalent to that of previous pure-water operation periods. Using an Am-Be neutron calibration source the mean neutron capture time was measured to be $115.6\pm0.6$ $\mu$s, which corresponds to a Gd concentration of $110.9\pm1.4$ (stat.only) ppm, as expected for this level of doping. This paper describes changes made to the water circulation system for this detector upgrade, the Gd loading procedure, detector commissioning, and the first neutron calibration measurements in SK-Gd.

    Abstract Electron antineutrino appearance is measured by the T2K experiment in an accelerator-produced antineutrino beam, using additional neutrino beam operation to constrain parameters of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. T2K observes 15 candidate electron antineutrino events with a background expectation of 9.3 events. Including information from the kinematic distribution of observed events, the hypothesis of no electron antineutrino appearance is disfavored with a significance of 2.40σ and no discrepancy between data and PMNS predictions is found. A complementary analysis that introduces an additional free parameter which allows non-PMNS values of electron neutrino and antineutrino appearance also finds no discrepancy between data and PMNS predictions.
