PRIMARY CONCEPT 1.1: Apply sound orchard practices
Critical Guidelines
1.1.1 Select cultivars with characteristics suited to your climatic and soil conditions to ensure long-term sustainability.
- Determine the marketability of the cultivar (market, demand, timing, size, keeping quality, yield).
- Only use healthy certified plant material.
- Use the recommended rootstock for your circumstances and cultivar.
- Do fruit and leaf mineral analysis.
- Contact your local consultant for planting guidelines.

1.1.4 Use only registered pesticides and plant protection products.
- According to the requirements of the country of destination.
- Concentrations and withholding periods are critical.
- The use of pesticides varies according to the specific fruit kind. For instance, what can be used for nectarines may not necessarily be used for plums.
- Refer to regulations of residue limits and to chemical companies for withholding periods.
- Refer to Hortgro Maximum Residue Levels (MRL) list
- Monitor quarantine pests regularly (Fruitfly, False Codling Moth, etc.).
- Follow integrated pest management (IPM) principles.
