Too Much Moisture!

Recent weeks have given us more rain than usual, and unfortunately, just about any time we see excessive periods of rain, we see an increase in disease problems. Some problems are already showing up, others are likely to follow. Quick action is the key to minimizing problems that diseases bring with them. Here are a few tips to help you.

 

Tomatoes One of the more common complaints about tomato plants is related to leaf diseases. Early Blight and Septoria Leaf Spot are common in our vegetable gardens and often end the tomato season prematurely.

Excessive moisture increases the occurrence of these diseases, so be prepared for some problems. Good disease control practices can help minimize disease problems. Start by making sure you mulch around your tomato plants. Mulching helps control the splashing of soil and the disease spores it contains onto the lower leaves. We like to use wheat straw, pine straw or alfalfa mulch. Preventive fungicides like Fertilome Broad Spectrum Fungicide can also be used.
 
Fruit Trees If you have done a good job keeping your fruit trees sprayed for leaf and fruit diseases already, don’t stop now! If you haven’t been applying anything, you may need to get started. We have several good disease control products for fruit trees. Keep in mind that not all products work on all fruit tree diseases, so it is important to make sure you are applying the right products to target the disease you’re are trying to control. Let us know what kind of fruit trees you have and we will help you select the right product.
 
Roses Black Spot and Powdery Mildew samples are already being brought in by customers. To reduce your chances of dealing with these diseases, start by planting your roses in places that receive lots of sun and good air movement.
Planting rose varieties that are naturally resistant to these diseases also helps. If you do find yourself dealing with these problems, fungicides will be needed. We have two by Fertilome that we use that provide good control, Liquid Systemic Fungicide and F-Stop.
 
Lawns Excessive moisture this time of the year often leads into the development of Brown Patch, a disease that creates irregular brown “patches” in tall fescue lawns and in severe cases, kills out areas of turf.
Warmer weather in the upcoming weeks will bring this one on. Although it is very common, most infections will only result in visual damage and eventually the lawn will recover. In years where the disease pressure is higher or in yards that are more prone to disease, prevention may be warranted. Use Fertilome F-Stop and start your applications before the disease gets started. That will be fairly soon. One other recommendation would be to avoiding excessive fertilizer this time of year.
