ABSTRACT:
An infestation of Peronosporales on plant leaves will only fully develop if the leaves experience a period of wetness of a duration sufficient to allow the penetration of zoospores into the stomata of the leaves. The duration of this period is temperature dependent. Apparatus is provided which includes a pulse generator arranged to generate pulses at a rate dependent on the ambient temperature, a signal gate controlled by a leaf wetness sensor to pass the pulses output from the generator only when the leaves are sufficiently wet to favor penetration of the zoospores, and a counter arranged to count the pulses passed by the gate to time a period the duration of which varies with temperature. Upon completion of timing, the counter outputs an infestation signal which causes a monitor counter to start counting the pulses output from the pulse generator whereby to provide an indication of the subsequent advance of the infestation. Successively generated infestation signals are arranged to cause successive monitor counters to start counting thereby enabling several overlapping infestations to be followed.
