Apply Fungicides before Problems Strike

The most effective fungicides are preventive sprays that help plants when they are vulnerable to disease causing pests.

When will fungus start?

Cool wet days in late spring or early summer are ideal conditions for fungus to put forth spores which can land and grow on young, tender leaves of annuals (tomatoes!) and trees especially with fruit. These spores grow on the living tissue and damage or kill the plant. To prevent severe damage, apply the appropriate fungicides for the plant you wish to protect.

To protect fruit trees and other plants susceptible to black spot, we suggest Fungonil. You will need to spray approximately every 7 to 10 days on a dry day while the cool damp weather is forecast.

To protect tomatoes, we suggest Serenade or similar biorational fungicide.  This type contains a product that helps fight off fungi that typically attack tomatoes.  For your planning purposes, you’ll need to spray approximately every 7 to 10 days through the growing season on a dry day so the product has the opportunity to dry on the plant surface.

Know your pest

For any pest control program, always confirm what pest you need to control. For example, a fungicide will do nothing for Japanese Beetle problems. We can help identify the issue if you bring us a sample in a sealed plastic bag or send a digital image.

Our pest-control products list what they are designed to control. Follow the instructions on the product exactly and you should be able to get through the challenges of crazy weather.
