|Abstract:||Double bean (phasoolui lunatus L.) is one of the laportant spool®! of beans grown in the yieiaity of towns in Kaaaraahtz^t. The beans fstoh good priea in market as a vegetable whioh is deliolous in taste. The gr%9n pods are not used as a vegetable in ths saw* way as French beans. Sitha? shelled green or dried beans are used. The shelled beans are oooked as vegeta ble whioh are potential source of proteins (20.? per cent), minerals (3.8 per otnt) and vitamins and rank next to soybeans. The beans are grown on large soale in the United States and used for canning and freesing. phaseplus lunatus is of two distinct types* the siera bean and the llaa bean. There are two sohool of thoughts about the speoies eonoept of doable bean and lima bean. Xdnaeaeus made two speoies of the two forms. 3alley (1940), on the basis of thirty aboreground contra sting characters placed slera, civet, sewee or oarollna bean under Phaaeolus lunatus L. and lima bean under Phaaeolus ll^enals *aof. Isolde (1943) presented consi derable evidence in favour of one speoies oonoept. Many botanists also prefer to place both types in the single speoies Phaaeolus lunatus h, Tarnell (1965) states that the so called two speoies £. lunatus, and J?, llmenals in fact belong to one species.double boan thrlvos wall in a eool dry eliaato with a rainfall ranging fro* $00 to 750 as. Double bean la a nlno sontns duration orop and irrigation facilities are ssaentlal for successful growing of the crop. Though it can bo grown in all types of soils, wall drained soils are prof Arabia. There are no naned cultivated varieties of Double boan in India. Plainly the polo varleitles are grown in hoae gardana in Maharashtra, Andhra Pradesh, Orissa and on the bills of Assail, #eot Bengal and also in Nopal. Th« orop la affected by various dlaaases snob aa root rot (?usarluai oolanl f. phageoll), oollar rot (Saorophoalna phe^oo^t (Hanoi.) Aahby ), anthraoaoso (fffAlt*ftW«*Mi UaillHihiaSHa). downy mildew (Phytophthora phaaooll). bacterial blight (Xantho*onaa phaaooll) and noaalo caused by virus. In July 1973, Oollar rot of Double boan (Phaseplus lunatus L.) eausod by jfWffittta^nt Phaaoqll (Maubl.} Asbby was observed in Agricultural College Imra, Poona. The disease was vary severe and the Incidence of tbt disease was varying to the extent of 50-60*. the affootod plants showed ooaplete wilting. Shredding of the bark at the oollar region was observed. 3ol«rotlal bodies wars also observed on oollar region of the affectedplants, float ay 5ten showsd rotting. Young seadllaga were killed aoaplttely. 3inse the disease was a aew outbreak not pre viously reported oa double bean froai Maharashtra and as it is also reported oa few other regetafele oropa, the prasaat laveatigatioa was uadertakea.
