What is now Ok for apple trees caterpillars poisoning?

Why only caterpillars, Peter?) Oh poison - so the whole fraternity) on apple trees at least 10 insect pests) The whole process should be carried out in early spring of dormant buds, when all the fierce enemies just wake up and try to settle on apple. The pre-cleaned of old dead bark (burn). The whitewash - you can add a bit of nitrofen.I did not try, but it is said that a good idea to put on the trunk after whitewashing protivogusenichny special glue.Nothing is more effective than spraying, alas, not yet invented, with carefully both the tree and the soil in the tree trunks, and that's what ... if you're talking about high efficiency - chemistry course (or a solution of malathion chlorophos (0,3-0 , 7%), systemic insecticides. I, for many reasons of chemistry refused.Moved to bioinsecticides - no harmful to people or animals or bees) Do not know how, of course, but there are always some new ones. Effektivnye- boverin, fitoverm, aktofit, Lepidocide, Bicol, entobakterin (neighbors sometimes add very good. Small doses of any insecticide (trichlorfon, trihlormetafos-3, etc.). I - no).And you can spray the whole summer, until the end of the growing season. Well, plus water extracts / decoctions of plants - the aerial parts and roots of tomato, wormwood (even in the far corner of the planted shrubs to hand was a)), tobacco, onions and garlic added. soap. Processing immediately after flowering once every 7 days. Well handles nests of caterpillars periodically removed and incinerated.Of course, the tree begins to bear fruit, all at once windfalls collect and pass away, and it is better to burn. This summer, tortured) Harvest was incredible, mountains of fruit drop (In autumn - clear the ground under a tree on fallen leaves, fruits, dig 10-15 cm.In general, if properly and regularly engaged in all these, the fight turns serious, especially if the old garden)) Time and effort is not enough. Therefore, the effectiveness is difficult to judge, but to 12 g did not do anything, and there was the activation of the enemies)

Irina, thank you very much for your detailed comment, give info, see what happens next season.

Peter, you still tell that it is necessary to protect and attract insects -entomofagov)) Yura wrote here about this https://insecta.pro/gallery/42125
Itself has not yet tried, but few have studied this issue and collect nests wintering larvae in the period from the end of the autumn leaf fall before bud break in the spring, store them until spring in the bank.Spring Bank closes fine mesh. From banks apantelesy fly and feed themselves without the caterpillars die. I read that the exact same simple way to deal with ringed moth - collecting eggs of a fall before bud break (wintering eggs). Walls are cut off, placed in a tank, in early spring cages are put in the sun.Hatched caterpillars die, and parasitic insects which fly over the net. Said insect - entomophages you can even buy a large number of islands in the biological laboratories greenhouses at mills

Ok, Ponil, thank you!

Well, my two cents in something again. All written Irina, especially in the chemical methods is not absolutely true, thatremoval (burning, burying) of fallen leaves in autumn, the removal of fruit drop (during the season), and removal of the fall from the trees for some reason not leafless leaves (there are usually overwintering stages of pests are waiting for spring); whitewashing, cleaning cracks on trunks and other. But again, if you are on your 6-12 acres are doing everything perfect and your neighbors do not have ...We get the monkey work.
As for treatments to trees bud - is valid only against the eggs of mites and San Jose scale, which in Moscow is not and never will be.Against the absolute majority of the pests of fruit insecticide treatment is carried out before flowering, but buds, and apples - after petal fall (against moth). Said Irina drugs are outdated even then, when I was engaged in cottage itself, ie 15-20 years. What to use - the network has everything, includingannually publishes the Official Handbook of permitted pesticides. Here in 2015 http://www.pesticidy.ru/ps-content/literature/files/Государственный_каталог_2015_2743_instructions.pdf.
Now again about the biological protection methods.All very nice in words, but in reality for suburban areas the effect can be only when all over the garden partnership (array) of large area All things at once and correctly, then it is possible for something to say, although the efficiency is very low and work biologics only in years LOW populations of pests.Effect of biological control have indoors (greenhouses, as produced by parasites, predators anywhere these greenhouses can not crawl / fly). In the open field effect is miniscule and does not pay the costs. By all the laws in the wild predator / parasite grows only after when the increasing number of casualties.No fodder - fertility and reduced numbers of predators, is - increased, but after a number of victims grew by order and apples bye-bye :).Well, you will get entomophages in biological laboratory at the greenhouse complex, but what's next? Why is it in your garden plot to linger? If it was full of their victims, certainly linger, but the train has left something - and in nature so arranged that never predator / parasite does not kill its own food base.And if the predators there still nothing to eat - will fly / upolzut / kick the bucket.
The wormwood and other folk remedies I will not say all this to a greater degree of myths and who want to see the effect he sees it.The young fruit arrays can be for some time without pesticides and receive a high quality crop, and old-growth (if you have a young garden, and around 10-15 with three more years of planting, the age of your site has no value) or use 2-3 times per season insecticides / fungicides / acaricide and get BMa decent crop, or consume organic products, but in small quantities. That something like that from my experience and summer resident (in the past) and a specialist in defense.

Yes forgot to say that in the laboratories at the mills are not hothouse grown entomophages for pest gardens / gardens gardeners - there is a specific set of not usable in the country :)

Thank you, Eugene, your professional resume only finally pushed me to the pleasant solution - starting from next summer have only environmentally friendly products already in the public get the number :) If you consider that just outside the huge monastery garden, which is terrible to say how many years, the .. .do not want to deal with a fool's errand)) Well ... maybe periodically pobryzgivat tomato extract to clean conscience and maintain that same faith in effect and in what folk remedies work))
