Wynboer Tips for August
PLANNING
- Plan herbicide programme as well as spring fertiliser and spraying programmes.
- Place the necessary product orders.
- Adhere strictly to the IPW guidelines
VINEYARD PROGRAMME
- Calibrate spraying pump and fertiliser sprayer.
Pest control
- The emphasis should be on correct mealybug control before budding.
- Follow the guidelines for winter treatment to the letter.
- Control snails if problematic.
Pruning
- Ideally vines should be final pruned in one action approximately 3 - 4 weeks before budding.
- Vines in frost prone areas may be pruned as late as possible.
- If budding stimulants are applied 3-5 weeks before budburst, a good synergistic interaction is obtained if the pruning (in one action) and application of budding stimulants are timed as close as possible to each other.
Herbicides and/or cultivation
- Before budburst, kill weeds with a full surface spray using a systemic product.
- If pre-emergence herbicides are used, be fully aware of the requirements for successful control as well as the accompanying dangers in some instances.
- Cover crops should be sprayed and then preferably flattened to ensure the best retention of dry matter, especially under dry land and in dry winter conditions.
- In wet years cover crops can be allowed to grow and die back naturally to extract excessive water from the soil.
Planting of vines
- Attempt to finish planting before the end of August.
- Keep some replacement vines in plastic bags to use where vines did not take.
Fertilisation
- A fertilisation programme must be drawn up for each block on the farm in collaboration with a fertiliser expert and/or viticultural consultant.
- If chicken manure is used as fertiliser, now is the right time for application.
Irrigation
- Undertake maintenance of irrigation system and chloronate.
- Supplement soils to field capacity before budding except when a deficit irrigation strategy may possibly require otherwise.
FINANCIAL
Contact Gert van Wyk for information about:
- Viability, cost and profitability analyses.
- Presentations on the economics of wine grape cultivation, industry overview, etc.
- Budgets and financial planning in the light of production cost, establishment costs and other industry parameters.
- Participation in the production plan/study groups.
