        Biological control of plant pathogens with the aim of reducing the harmful effects of pesticides on human health threats, environmental pollution, eliminating non-target organisms and the emergence of resistant pathogens is a priority. In this regard, the use of antimicrobial potential of plant metabolites, have been discussed in recent years. In this study the effects of ethanol extract of Water Cress (Nasturtium officinale L.) on the growth of Fusarium solani, the causal agent of Potato dry rot, in vitro were investigated. The experiment was performed in the frame of a randomized complete block design with six treatments and four replicates. The treatments were 300, 400, 500 and 600 mg/ml of extract of Nasturtium officinale L. and a fungicide and were as controls. For this purpose, the plates of (PDA) medium were inoculated with the suspension spore of Fusarium solani (1×106 spore/ml) and the disk diffusion method was used to evaluate the effect of the extracts on the growth of the fungus. The results indicated that all concentrations of the extract used, were effective in controlling the growth of the fungus and the effect was close dependent. These rents suggest that the extract of Nasturtium officinale L. can be used to control in the growth of Fusarium solani. However, recommended further investigations on control of the fungus in potato are needed.   Manuscript profile

        With due attention to the conditions of climate in Beyranshahr (lorestan). and for controlling about fair recommend , date of planting , also determining about the fair way of adornment , of planting , in other words , accumulation of desired crucible in Hectare unit for  K.S.C 647 digit . This plan based on the way split Factorial in the model of random blocks, four repeat, in village of gollab (Beyranshahr – Lorestan), was done. In these experiments from the stage of planting to harvesting , constant taking note about researches of maize , height of crucible , roasted maize – number of days reading physiology , measuring functions particles , such as number of seeds in a row, number of seed row , weight of  roasted maize seed , weight of seed thousand , dry weight of roasted maize wood , function biologic , height of crucible , planting indicator , indicator of leaf surface , number of ending leaf , about every patient will do and calculate . The summary of resulting about experiment and contrasting of average of simple effects, and against measured characteristics, would show that simple effect of planting date and effect of planting adornment against seed function isn’t meaning less. But most of seed function in crucible accumulation, earned was (85/000). Those 14.653 tons in every Hectare In against effects of planting date , accumulation of  crucible and planting adornment the most seed function in date of second planting (31/May/2014) and seed accumulating (85/000) at distance of lines 25 cm (two rows) with 15/849 tons in Hectare will be attained . In this research, for this region, we recommend, date of second planting (31/May/2014) and seed accumulation (85/000). For germinating and grow thing of maize plant, we will have a Fair opportunity, planting characters tics and seed function, will have a fair development. In the end, the part of source will be supported and seed function will be increased. In the meantime, we don’t recommend the date of third planting, because there isn’t enough opportunity for decreasing the wet of maize seed in the farm, and it isn’t available to have a bed for other product.   Manuscript profile
