摘要:

Apparatus of the type often referred to as ‘Patternator’ has been constructed which enables the distribution and rate of discharge of agricultural spray nozzles to be measured accurately and rapidly. It is also suitable for checking and recalibrating nozzles whose characteristics may have changed during use.

摘要:

The abrasive action of a copper fungicide on four nozzles commonly used in Nigeria when spraying cocoa for black pod control was evaluated. The spray solution flocculated and the nozzles frequently blocked indicating the need for an efficient filter. The single hollow cone type nozzle and the variable spray nozzle were the most highly abraded.
