The average planting density was 2, 850 vines per hectare, compared to the mandated 2, 500 to 9, 000 vines per hectare.

Controlling can be easy with practicing many cultural control and sanitary measures such as stubble rotting, adjusting planting date and adjusting planting density.
13.
Controlling the disease involves eliminating conducive conditions as much as possible by altering planting density and carefully timing applications and rates of nitrogen.
14.
The planting density is between 2, 500 and 5, 000 vines / ha ( 1, 000 to 2, 000 vines / acre ).
15.
Planting density is around 2, 000 2, 500 vines per hectare, though the maximum authorised density is 4, 500 vines / ha.
16.
He recently joined forces with Italian researchers to introduce a new line of olive tree designed to increase planting density and raise potential yield.
17.
In the UK, there is a nationwide experiment for silvopastoral systems in which a number of tree species and planting densities are being studied over a range of sites.
18.
Hydraulic structures ( inlet and outlet zones ) should be designed to ensure adequate pre-treatment and prevent large nutrient spikes'Landscape design, using appropriate plant species and planting density are also necessary.
19.
Plant diseases can also be partially controlled by use of pesticides and by cultivation practices such as crop rotation, tillage, planting density, disease-free seeds and cleaning of equipment, but plant varieties with inherent ( genetically determined ) disease resistance are generally preferred.
20.
In more recent trials in the Prince George Region of British Columbia ( Table 6.39 ) and in Manitoba, planting density of white spruce had no effect on growth after up to 16 growing seasons, even at spacings as low as 1.2 m.
