Buying fresh vegetables and greens in shops, we do not even represent how many the chemistry gets to us to food together with these products.
The scourge of large-scale greenhouse facilities is web tick and the whitefly. Saplings undergo continuous processing in greenhouse facilities pesticides. If such processings are not carried out for any reasons, then the web tick breeds in geometrical progression and destroys all landings.
However there was new biological way of pest control in greenhouse facilities. One of types of biological agents is the predatory tick – fitoseyulyus. The tick and his larvae are carnivorous and destroy several types of web pincers. The female of akarifag destroys up to 30 young ticks or up to 5 adult wreckers a day.
Fitoseyulyus exhausts the victims and lays eggs in the places occupied by wreckers. After cleaning of plant from parasites the predatory ticks get over on other plants. If within four days of akarifaga do not find to themselves some food, then they just perish.
Prevention and fight against web tick by means of biological agents reduces risk of poisoning of the person with pesticides. At the correct use of biological medicines it is possible to refuse more or completely chemistry. Continuous monitoring of plants, for the purpose of establishment of presence of parasites is for this purpose necessary.
At the first signs of appearance of web tick it is necessary to place bag of biological agents on each plant near the struck sapling. And for prevention it is possible to hang up such bags on all plants.
However biological protection of plants so far very expensive means, and chemistry remains cheaper and available method of pest control. Especially as storage lives of biological agents are extremely limited. Let's hope that in the future the situation will change in favor of healthy food without chemistry what biological protective equipment of plants will help with.
