So endangering rot loses its terror on tomatoes
The causes of late blight on tomatoes are not completely clear. The results so far point at least the way to an effective prevention. How to avert the dreaded plant disease, convey the following lines.
Correctly interpret the damage image
The final blight on tomatoes is neither a fungal infection nor a pest infestation. Rather, the scientists assume a metabolic disease. The damage is devastating. It manifests itself in the field just as often as in the greenhouse. How to recognize the symptoms:
Current status of the cause research provides information
Accompanied by the final blight is a shortage of the plant with the vital nutrient calcium. A healthy tomato plant receives with the water at the same time a sufficient amount of calcium, which is transported into the leaves and from there into the tomatoes.
Fluctuations in irrigation, strong growth, too low soil pH, and excessive salinity interfere with this transpiration flow. Since the fruits are by nature less calcium-rich than the leaves, the deficiency here is particularly devastating.
Thus, end of life blight gets no attack points
Use the following measures to immunize your tomato plants against the metabolic disease:
If the emergency has already occurred, the specialized trade offers special calcium fertilizers. These work very fast when applied over the leaves. Alternatively, dissolve 30 grams of calcium nitrate in 1 liter of water and water the diseased plant with it.
Tips & Tricks
You can easily determine the pH value of the soil yourself. In DIY stores and garden centers inexpensive test sets are available that can be used without chemical knowledge. A simple staining reaction indicates what the lime content of the soil is.
