preparation example Construction

[0029] Representative organic liquids that can be used in the preparation of emulsifiable concentrates of the present application are aromatic liquids such as xylene and propylbenzene fractions; or mixed naphthalene fractions, mineral oils, substituted aromatic organic liquids such as dioctyl phthalate; Kerosene; dialkylamides of various fatty acids, especially dimethylamides of fatty diols and diol derivatives such as n-butyl, ethyl or methyl ethers of diethylene glycol, triethylene glycol of methyl ether. Mixtures of two or more organic liquids are also often conveniently employed in the preparation of emulsifiable concentrates. Preferred organic liquids are xylene and propylbenzene fractions, with xylene being most preferred. Surface active dispersants are typically employed in liquid formulations and are present in an amount of 0.1 to 20 wt%, based on the total weight of the dispersant and synergistic composition. The formulations may also contain other compatible additi...

[0043] Evaluation of fungicide mixtures against leaf blotch of barley (Mirroria barley (Rhynchosporium secalis): Bayer code RHYNSE) for improved plant physiology (including increased yield and improved green change) :

[0044] The results in Tables 1-3 were obtained using foliar application in a small plot (2.5 x 8.0 meter (m)) research experiment evaluating the composition in winter barley (Hordeum vulgare, HORVW). Two treatments were applied at crop stages BBCH 31 and 43-49, respectively. Application was performed using a knapsack sprayer (250 kPa) equipped with a 2.5 m boom equipped with 5Agrotop-AM1 1002 flat fan nozzles mounted at 90 degree orientation at 50 centimeter (cm) intervals. The output of the composition diluted in water was 200 liters per hectare (L / ha). Visual assessment of control of leaf blotch of barley (Rhynchosporium secalis, RHYNSE) is reported as percentage (%) of infected leaf area and was reported at application 1 (in BBCH 31 In the case of untr...
