Prepare the plant against the effects of moisture in the greenhouse

With the arrival of winter and the first rains, there are favorable conditions for the development of fungal and bacterial diseases, which develop better in conditions of high relative humidity.

In greenhouses and other protected crops, this phenomenon is aggravated especially if there are no means of forced ventilation.

In addition, the benign thermal conditions that have occurred so far favor the vegetative growth of the plant and may favor a greater susceptibility to diseases, especially if fertilization is unbalanced.

How to take measures before the arrival of winter?

Regardless of the ventilation management measures and phytosanitary treatments aimed at preventing and controlling diseases such as mildew or botrytis, the farmer can implement complementary techniques aimed at improving the response to diseases of this type:

  • Control nitrogen inputs: unbalanced fertilization rich in nitrogen (especially nitric N) makes the crop more susceptible to damage caused by fungi and bacteria.
  • Use of biostimulants such as silicon, which strengthens the cell wall, helping to prevent the penetration and spread of pathogens.
  • Use of osmoregulators, stimulants that counteract the effects of low temperatures, strengthen the plant and improve productivity.

Plymag products that help us in Winter

BETAPRO, formulated with glycine betaine containing Ascophylum nodosum extract: improves the plant’s response to stress while stimulating growth and production.

It contains mannitol, which together with glycine betaine keeps the cellular machinery going, by preserving its properties and raising the freezing point.

PLYSILC provides silicon and potassium, with the following beneficial actions. It does not provide nitrogen.

Silicon

Reinforcement: the silicon crystals reinforce the tissues and strengthen their resistance. It is part of the structure of trichomes.

Physical barrier: the layers of gel make it difficult for the germ tubes and haustoria of fungi to penetrate.

Potassium

It plays a central role in the development of crops under environmental stress. Potassium improves the response to cold (resistance to frost) and hydration (maintenance of turgor).
