Pathogenicity of some pycnidial fungi on faba bean seeds
1997
Simay, E.I. (Enterprise for Extension and Research in Fruit Growing and Ornamentals, Budapest (Hungary))
In the course of pathological tests conducted at the Agrobotanical Centre, Tapioszele, Greece, several pycnidial fungi were isolated from various hosts including faba bean and other leguminous plants. Twenty isolates of 11 species were tested on seeds of Vicia faba L. The highest rates of seedling symptoms and decayed seeds resulted from infecting the seeds with Ascochyta fabae Speg. Ascochyta pisi Lib., Coniothyrium fuckelii Sacc., Phoma exigua var exigua Desm., Phoma medicaginis Malbr. and Roum, and Phoma medicaginis Malbr. and Roum var pinodella (Jones) Boerema also caused symptoms on seedlings and seeds; however, the following produced either no symptoms, or only sporadic symptoms: Ascochyta rabiei (Pass.) Lab., Ascochyta viciae Lib., Phoma glomerata (Corda) Wollenw. and Hochapf., Phoma herbarum var medicaginis Westend., and a Phoma sp. obtained from the phylloplane of V. faba

The paper presents some data concerning the effectiveness of the biological products, Applaud 25 WP, Dimilin 48 TM , Nomolt 15 SC, Nissorun 10 WP, Flumite 20 SC and Pyranica 20 WP, categorized as insect growth regulators (IGR), as well as the products Novodor 48 TM, Biobit XL and Dipel 2X, whose action is based on Bacillus thuringiensis var. tenebrionis and B. thuringiensis var. kurstaki bacteria. Except Pyranica 20 WP, whose acaricidal action is effective against all the development stages, all the other products tested had a more limited action, affecting only certain species of pests or development stages and, therefore, they can be used only in different formulas of integrated control. The product Applaud 25 WP has a good ovicidal and larvicidal effect in the white fly (Trialeurodes vaporariorum Westw.) control. The products Dimillin 48 TM, Nomolt 15 SC, Dipel 2X and Biobit XL, significantly reduced the population of Mamestra and Pieris larvae, while the product Novodor 48 TM can be used with good results against the Colorado beetle (Leptinotarsa decemlineata Say.) larvae. Also, the products Nissorun 10 WP , Flumite 20 SC and Pyranica 20 WP assured successful control of common red spider (Tetranychus urticae Koch.). All the products acting as IGR assure a phytosanitary protection of 30-45 days for one treatment.

Hammer milled and differently rolled barley for growing pigs Texto completo

The effects of grinding method of barley on the apparent faecal digestibility, rate of passage through the gastrointestinal tract, protein utilization responses and growth performance of growing pigs were assayed in two separate experiments. Barley was ground by a hammer mill and by three different rolling mills into fine and coarse batches. Digestibility of dry matter and energy, daily gain and the feed conversion ratio of rolled barley was as good for rolled as hammer milled barley when the roller gap was set properly. The grinding method affected N-excretion without any change in N-utilization. It was concluded that palatability had a greater effect than digestibility on pig performance. | V | ok
