Добре,къде тук е разликата между накапкване и напръскване -с 5 мл.разтвор на междурамие??? Според ммен само убъркваме колегите който ще третират за първи път с ОК.Аз използвам еднолитров пулвелизатор, пръска и на.струя и и на метла,при 1натискане изпръсква 1 милилитър,впръсквам по пет струи в междурамие. Е НАКАПКВАМ ИЛИ НАПРЪСКАМ??? Къде е разликата,дори да извадя питата и да ги напръскам на метла разтвора ми е същия.Ако има много акар се слага 50 или 75 гр ОК на литър.Това е.

Spring/Summer dribble (brood present)
The most impressive thing beekeepers notice the first time they use oxalic (as a summer treatment on badly-infested colonies with “curlywing” virus) is the remarkable change in the appearance of the bees. A week following treatment, the dull, listless, “demoralized” looked noticeably bright and peppy, and curlywing was nowhere to be seen. I know that “peppy” is not a scientific term, but you’ll see what I mean.
Gregorc and Planinc (2001) found that in summer 3.4% in 48% sucrose worked best. There was no observed harm to bees or buildup. Three treatments in August 9 days apart gave 44% mite kill.
Ellis and Aliano found that three weekly summer dribbles of 40 ml of 3.5% w:w per single box of bees resulted in a 60% reduction in mites (although the control experienced a 41% reduction without treatment); for the similar treatment with Sucrocide, the mite population increased by 35%! Ellis feels that the brood acts as a “robust buffer” of mites that prevents treatment under those conditions from being very effective.
Asking around, the jury’s still out, in my opinion as to whether OA summer treatment is worthwhile, due to relatively low efficacy, and demonstrated damage to the brood (see below). The later in the season, and the smaller the brood nest, the more effective the treatment is. In the short term, though, it sure causes a major drop of mites!
