Έλεγχος θείου - καταστρέφει το θερμοκήπιο! Οι συνέπειες της χρήσης θειούχων πούλιων

To get rid of pests, pathogens of various diseases, all kinds of animals and mold, gardeners can use chemicals to treat greenhouses. Often, when choosing a chemical preparation, the choice falls on the sulfur block, as it is inexpensive and easy to use.

But few people read the instructions for use before using it or ask themselves: «Is it possible to use it in a metal greenhouse covered with polycarbonate?» Answer: «Not recommended, as the greenhouse may be damaged»

Why? Let's take a look at the sulfur checker application guide.

«To avoid corrosion, lubricate metal objects with a thick layer of grease or grease» We recall chemistry lessons. The combustion product of a sulfur bomb is gaseous sulfur dioxide (S + O2 → SO2; 2SO2 + O2 → 2SO3). And it, combining with water vapor or condensate in the greenhouse, forms sulfuric acid (SO3 + H2O → H2SO4), which interacts with metal (including galvanized), forming rust.

Thus, after using a sulfur block, the greenhouse frame may become rusty, and the polycarbonate may become cloudy. This will cause some damage to the greenhouse.

It is worth noting that you need to be careful when using a sulfur checker. The sulfurous anhydride released during the burning of the bomb is toxic and, if inhaled, can cause severe poisoning and burns of the respiratory tract. Therefore, precautions must be taken. When using, wear a respirator mask and safety glasses.

To get rid of pests and diseases, if they really exist, it is possible and necessary in other ways.

In the process of caring for the greenhouse, it is strictly forbidden to use: solvents, degreasers, detergents and cleaners. It is permissible to wipe the greenhouse only with high shaking.
