Purpose to evaluate the influence some qualitative parameters of water, chemical control with acaricides cyhexatin, propargite and acrinathrin, adding yet different nutrient salts in the form of leaf fertilizer zinc chloride, manganese chloride, potassium phosphite, magnesium sulfate and urea in their mixtures, applying on the mite B. phoenicis. The first part of the work used in the pond water Main Campus of Jaboticabal, having performed three experiments with 9 treatments and 4 replicates each, direct action on the tails of the mite in the Laboratory of Acarology the Fitossanidade Department of UNESP, Jaboticabal-SP. The second part of this work, we used the waters of the counties of Pirassununga, Pirangi and Itápolis, two experiments were conducted with 27 treatments and 4 replicates um. As waters used in experiments were analyzed separately and after the different mixtures, pH, electrical conductivity, temperature and oxygen dissolved. The two pieces of work, each orange fruit was considered a fruit used repetition. The first work, received no treatment with plant protection product in the 6 months prior to the experiment, and fruit used in the second study, received no treatment plant in the 13 months preceding the trial. The doses of products used in treatments were expressed as ml of commercial product per 100 L of water: cyhexatin to 50 mL; propargite to 100 mL, 10 mL acrinathrin as recommended by the manufacturer and a control without aplication. The second part of the work has not used the product cyhexatin because information from the manufacturer that the same would no longer be marketed in Brasil. Orange used with symptoms of the disease... (Complete abstract click electronic access below) / Mestre

The aim of the experiment was to evaluate the reaction of chosen potato varieties to the application of leaf fertilizers. The speed of their action and, together with combination with other interventions (common application with fungicides), and also the economics of their application belong among the advantage of leaf fertilizer application. In 2012 and 2013 there was an experiment established in 380 m above the sea level. In this experiment the effect of application of urea solution, Lignohumate, and Energen Fructus was evaluated in the varieties with a different length of vegetation period Magda very early, Adéla - early, Laura and Satina semi early and Bionta - late. The rate of sprouted plants, the yield of tubers, the proportion of tubers of consumer size, the number of tubers under cluster, an average weight of one tuber, the number of stems per a plant, and the content of starch were evaluated in these plants. It was found out from the results that in 2012 Magda and Satina varieties reacted with an increased average weight of one tuber after the application of all leaf fertilizers. The effect of Lignohumate was the most positive in this year; it increased an average weight of one tuber in Magda, Adéla, and Satina varieties. In comparison to that, in the second year of the experiment there was a positive reaction to additional fertilizing with Lignohumate, Urea, and Energen Fructus, leading to the increase of an average weight of one tuber in Magda, Adéla, Laura, and Bionta varieties. In 2013 there was the highest influence on an average weight of one tuber caused by the use of Urea, namely in Magda, Adéla, Laura, and Bionta varieties.
