What to Do When Strawberry Stems and Petals Turn Red? Here Come the Latest Control Methods
When it comes to strawberries, many people may be secretly drooling. It is fair to say that the strawberry is truly a very charming fruit. At present, there is more and more greenhouse strawberry cultivation on the market, so quite a few growers are asking: what causes strawberry stems and petals to turn red, and does it mean the plants are sick? What should be done? So today let the editor answer this question for everyone.
1. Reasons for strawberry stems turning red
If strawberry stems show reddening, there are many possible reasons. First, it may be because the winter temperature is too low and the absorption rate of phosphorus is low, so the nutrients in the strawberry leaves cannot be transported, ultimately producing anthocyanins and causing the stems to turn red. Second, as the number of years of strawberry cultivation increases, relatively aged stems and leaves will also show reddening, which is a normal phenomenon of natural decline. In addition, during the cultivation process, field management work such as watering, fertilizing and loosening the soil is not handled properly, which can also cause strawberry stems to turn red. Finally, unsuitable growing conditions, such as too high or too low a growing temperature, too high or too low humidity, poor soil permeability, and poor drainage, can all affect the normal growth of strawberries and cause the stems to turn red.
2. Reasons for strawberry petals turning red
Strawberry petals turning red is mainly caused by two reasons. The first reason is that the flowering period of strawberries happens to coincide with low-temperature weather, and under such conditions the anthocyanin content increases, so the petals we see appear red, sometimes even purple-red. If temperature regulation is not carried out in time, leaf curling and withering may also occur. The second reason is that it is a precursor to powdery mildew and gray mold. When field humidity is too high, this can also cause strawberry petals to turn red and will also affect the growth of young fruit. If the disease worsens, it will seriously affect the yield and quality of strawberries and cause them to lose their economic value.
3. Control methods
Although reddening of strawberry stems and petals has little effect on the strawberries themselves in the early stage, if control is not carried out in time, the loss to growers can be very great. Generally, when this phenomenon appears in a strawberry field, we need to strengthen field management and reasonably regulate temperature, humidity, permeability and so on. When necessary, Liangguoan can be mixed with an appropriate amount of Diliwang and Wofengsu and sprayed. Also, when petals turn red during the flowering period, it is necessary to prevent gray mold and powdery mildew, so Liangguoan mixed with an appropriate amount of garlic oil should be used for control.
⟦NL>If strawberry stems turn red or petals turn red during the growth process, then we first need to conduct a comprehensive analysis based on the season and time, the affected part, and the cause, so that we can effectively prevent and control the occurrence of diseases and achieve the effect of stopping losses in time.
