    All the planting (different varieties of garden strawberries and earthwalkers) this summer was cleaned by someone ate. In the spring she fed, weeded, sprinkled humus and spilled copper sulphate. What to do? All thrown away or you can leave a mustache?

      The indirect culprit of the “defeat” on the strawberry garden, which was organized by a company of leaf-eating pests (as I suppose, among them were strawberry leaf beetle, May beetle larvae, K adult individuals of raspberry-strawberry and nettle-leaf weevils, caterpillars of some species of butterflies and leaflets), can be considered ... this year's unusually good spring. It was such April and May - warm, without torrential rains and freezing frosts - that contributed to a sharp increase in the number of insects and their good appetite.

      Mechanical damage to the leaves is significant, but still not critical for plants. I suppose that in the summer, of course, there was no large harvest from such plants, but still the plants survived and recovered. Mustaches from such bushes can be taken.
      But what conclusion should be drawn for the future? We cannot influence the weather, but to be more attentive to agricultural technology is quite feasible. The reader’s mistake is that, like many gardeners, she did not understand the features of different groups of plant protection products - fungicides (protected against diseases) and insecticides (protection against pests). She carried out the processing of plants with copper sulfate and believed that chemistry was enough. But the solution of copper sulfate is a means of preventing and protecting plants from only a number of fungal diseases and in no way affects the vital activity and activity of insect pests!
      To protect against such unpleasant surprises, I recommend that you always carry out in the spring at the beginning of plant growth 7-10 days before flowering with an insecticide against leaf-eating and sucking pests. The choice of suitable drugs is wide enough - these are inexpensive drugs such as kalbofos or colloidal sulfur, and more modern and safe for humans drugs.
      Preventive treatment is needed even if you have never had anything like this before - pests can get to you from neighboring sites or quietly get to you with new planting material in the fall. In hot years with a large number of pests, two treatments may be required.
