Pigeonpea and chickpea Insect identification handbook
(IBE 026). 1989. 120 pages. 10 x 18 cm. Paperback. ISBN 92-

This illustrated bulletin deals with insect pests that attack pigeonpea
and chickpea, two major pulse crops in the semi-arid tropics. Information
is given on the description, biology, and distributed of these
insects, together with the symptoms of damage they cause, and
methods of control. Descriptions of several beneficial insects parasites,
predators, and pollinators, are included, since it is important to
first determine the role of insects found on crops rather than to
assume that all insects are harmful and need to be eliminated.

New implements for crop production in the semi-arid
tropics

A suite of simple bullock-drawn implements has been developed at
ICRlSAT to form broadbeds and furrows and to carry out subsequent
field operations easily. Agribar II, an improved version of the Agribar
fitted with a four-row planter, can sow various crops and perform
tillage operations. Simple implements based on a T-bar have been
developed for making broadbeds, applying fertilizer, sowing, and
interrow cultivation. A crust breaker was developed to enhance
seedling emergence through the surface crust. A spinning-disc
knapsack sprayer and a groundnut digger have also been developed
to meet specific requirements of farmers who grow groundnut in the
semi-arid tropics. (Summary in Fr.)
