Black flies, often small and agile, can cause significant damage to tomato plants by feeding on the sap and spreading diseases. They typically appear on the leaves, stems, and sometimes the fruit of the plant, making timely control measures crucial.

Ingredients for the Anti-Fly Spray

To prepare the homemade spray, you will need:

  • 250 ml of raw milk: Milk is believed to help in strengthening plant defenses and providing a protective coating that can deter pests.
  • 5 drops of iodine: Available at garden centers or pharmacies, iodine acts as a mild disinfectant and can help in managing pest infestations.
  • 2 liters of water: This acts as the carrier for your active ingredients, ensuring they are diluted to a safe concentration for use on plants.

Step-by-Step Guide to Preparing and Using the Spray

1. Mix the Ingredients:

  • In a container, combine the raw milk and iodine drops.
  • Add 2 liters of water to the mixture and stir thoroughly to ensure everything is well blended.

2. Fill the Sprayer:

  • Transfer the mixture into a 2.5-liter spray pump. This type of sprayer will help you apply the mixture evenly and reach all parts of the plant.

3. Application:

  • Generously spray the mixture onto your tomato plants. Make sure to cover both the upper and lower sides of the leaves, as well as the stems.
  • Focus on areas where you notice the highest concentration of flies.

Best Practices for Application

  • Apply Early in the Morning: Spraying in the early hours helps ensure that the plants have time to dry during the day, reducing the risk of fungal diseases.
  • Repeat Regularly: Depending on the severity of the infestation, it might be necessary to apply the spray multiple times, typically every 7 to 10 days.
  • Monitor Plant Response: After the first application, keep an eye on your plants to see how they respond. If there is any sign of distress, dilute the mixture further or reduce the frequency of application.

Additional Tips

  • Cleanliness: Keep the garden area clean and free of debris to reduce the chances of pests.
  • Companion Planting: Consider planting companion plants that naturally repel flies and other pests. For example, read more about natural aphid control with tomato leaf spray.
