Growers are always interested in techniques that might enable them to detect stress in their crops more quickly. One such technique is chlorophyll fluorescence because it can be used as an indicator of photosynthetic activity.

Powdery mildews of rose and herbaceous perennials are widespread, common and potentially very damaging diseases. While fungicides still remain the primary method of control, the efficacy and crop safety of individual fungicides against powdery mildew diseases on different crops is likely to vary.
Growers and researchers are well aware of the need to use water efficiently (HW, 20 May, 9 September and 11 November 2011). The present research examined how to deploy a limited number of moisture sensors to predict the substrate water content of a large number of containerised trees.
Young rose plants produced for cultivation in gardens are now most commonly raised in containers and sold in spring. Customers are usually seeking compact, well-branched specimens and such plants can be produced in many different ways.
