Question: Is root cancer harmful to fruit trees?

Answer: Currently, most researchers have come to the conclusion that root cancer is practically harmless. Saplings in the nursery and mature trees in the garden with cancer tumors on the roots grow no worse than healthy trees. According to the staff of the I. V. Michurin Research Institute of Horticulture (Michurinsk) I. I. Vanin and S. N. Stepanov, no cases of tree death from this disease were observed. However, among gardeners there is still an opinion about the harmfulness of root cancer. They reject planting material with cancer growths.

I.I.Vanin at the I. V. Michurin Research Institute of Horticulture laid an experiment with 140 trees affected by root cancer. Many of them had growths on the root collar and main roots. They dug up 31 trees, of which 22 were without growths, in 9 the old ones disappeared, but new ones arose on thin roots.

Question: How to store pesticides?

Answer: All pesticides must be stored in special warehouses or storerooms. These rooms are placed in a dry place, they must have good ventilation, sound floors, walls, roofs, doors and locks; should be isolated from food and fodder storage areas. It is strictly forbidden to store pesticides together with other goods, in open areas, under a canopy and in damp basements.

Small amounts of chemicals can be stored in iron cabinets, wooden chests (boxes, chests) installed in dry rooms.

Question: In the special literature there is an expression: "active temperatures". What does this mean?

Answer. The growth and development of all plants takes place at specific temperatures for each of them. Most fruit plants and grapes begin to develop at a temperature of + 10 and above. For their growth and ripening of the crop during the growing season, a certain amount of heat is required, that is, the sum of degrees of average daily temperatures. This will be the sum of active temperatures.

For example, for the ripening of grapes, it is required from +10 in spring to +10 in autumn, for early varieties 2100-2600, middle 2600-2800, late 2800-3000 and more.
