Besides its known systemic activity, triadimefon acts in the vapour phase.This vapour phase activity of triadimefon was shown for powdery mildew on cucumbers and barley in greenhouse experiments at concentrations recommended for use in the field (I00 and 250 pg/ml) and also at substantially lower concentrations.The degree of vapour phase activity is dependent on the distance from the spray deposit.In experiments with radiolabelled triadimefon, it was observed that gaseous material was deposited on untreated barley plants, thus either keeping them free from attack or reducing infection.

In July and August 1990, symptoms of verticilliosis were common in maturing crops of linseed sampled in Hertfordshire, UK and throughout Germany. Grey chlorotic or brown stripes were observed on green stems; on maturing, light brown stems the stripes were dark brown. Symptoms frequently extended along the whole length of the stems and branches up to the capsules, and often spread completely round the stems. Black microsclerotia developed abundantly in stems with these symptoms and Verticillium dahliae was consistently isolated from them. The incidence of verticilliosis increased from 50 to 100% in untreated plots (cv. Antares) between 8 and 22 August at Rothamsted, UK and was not decreased greatly by fungicide treatments. The incidence ranged from 49 to 98% on cultivars and breeding lines in trials at Thule, Germany on 9 September. V. dahliae was isolated from seed from Rothamsted plots at an incidence of < 10%

French bean (Phaseolus vulgaris L.), a member of family fabaceae, is one of the most ancient and popular warm season vegetable crop grown worldwide for its green pods. It is an important source of protein, calcium, iron and vitamins in human diet. The crop is known by various names as French bean, common bean, snap bean, kidney bean and navy bean. In India, it is commercially cultivated in Himachal Pradesh, Jammu and Kashmir, hills of Uttrakhand, North-Eastern states and peninsular India, covering an area of about 1,50,000 ha with annual production of 4,20,000 tonnes and ranks 4 th in green bean production in the world. Its cultivation in Northern Indian plains is rather restricted in account of limited period of favorable weather conditions. It occupies an area of 3,197 ha with annual production of 33,112 metric tonnes in Himachal Pradesh. Biocompost and vermicompost supplement the nutrient requirements of crops. Concerning the economic sustainability, the low cost of compost is useful to farmer as well to human society. Vermicompost is reported to be rich in nutrient elements (Jambhekar, 1992) and biocompost also contains high amount of nutrients than ordinary compost or FYM.
