Ascochyta Blight<br />

Although ascochyta blight is listed among the diseases attacking chickpea in<br />

Cyprus, its importance is minimal. The first record of its occurrence described<br />

the disease as causing appreciable economic losses, very destructive on local<br />

cultivars and apparently of recent introduction, when referring to its appearance<br />

in April 1954 at the Central-North part of Cyprus (Gregoriou and Papadopoulos<br />

1957). It was further stated that some resistant cultivars tested locally, showed<br />

considerable promise. There appear to be no other records of occurrence or<br />

severe epidemics of the disease, nor of any substantial yield losses in Cyprus.<br />

Consequently no research program on ascochyta blight was undertaken in the<br />

past, or is in progress at present.<br />

Various production factors in Cyprus may be responsible for the near elimination<br />

of the disease: (a) spring sowing with rising temperatures and low rainfall<br />

normally falling on isolated days, does i -t favor its spread, (b) chickpea stubbles<br />

are removed from the field and used as livestock feed thus leaving no debris to<br />

carry the disease, (c) scattered fields of small area make it impossible for the<br />

disease to spread from one field to another, and (d) chickpea is grown in rotation<br />

w;th other crops which prevents the carry-over of the disease from season to<br />

season. All these factors seem to have led to a considerable depletion of the<br />

available amount of disease inoculum.<br />

Winter Sowing<br />

Winter sowing is not practised now on a commercial scale. If it proves to be a<br />

feasible and profitable practice, it can be expected that a big percentage of the<br />

spring-sown area will be converted to winter sowing.<br />

Strategy for Introducing Winter Sowing<br />

The advantage of winter sowing over spring sowing must first be established<br />

beyond any doubt. From preliminary trials it is evident that there are yield<br />

increases in both grain and straw of chickpea when sown in early winter, as<br />

compared with spring sowing. No frost damage or ascochyta incidence were<br />

recorded; plants survived through the winter but flowers did not produce pods<br />

until after the beginning of ApriL. This resulted in thn lowest pods being higher<br />

above the ground than with spring-sown plants, which isan advantage as regards<br />

combine harvesting. Weed control is a problem with winter sowing. Chemical<br />

weed control trials are in progress and there are promising results.
