Were developed new compositions preparation against pests and diseases of plant: Insekto-acaricide “Antipest”, Fungicide “Antifungal”, a drug against of overwintering pests “Proinsekt” and nutritious preparation “Si-humate”.The effectiveness of trial oil-emulsion preparation “Proinsect” was assessed by the spread of pests - San Jose scale (Diaspidiotus perniciosus) and mountain ash bentwing (Leucoptera scitella Costa) on treated trees. According to field testing, the efficiency of preparation “Proinsect” exceeds the effectiveness of one of the best imported oily preparation “Sipcomol”, which was selected as a reference.Joint content in composition of synthetic pyretroids with turpentine oil, supposedly synergism takes place (turpentines cause prolonged action of synthetic pyrethroid). In working solutions, obtained from turpentine oil containing composition concentration of pyretroid is low, but it is enough during the whole period of pest development cycle. According to the comparative field testing of “Antipest” and imported preparations, against for fruits pests their efficiency is at almost one level, despite the low content (by 30–40%) of pyrethroid (cypermethrin) in “Antipest”.The developed phosphate preparation “Antifungal” is a little bit less effective compared to Bordeaux mixture. If well take into account significant decrease of intensity of disease spread and development after the action of phosphate preparation, also very low toxicity zinc hydro- and dihydrophosphates compared to the blue vitriol (Copper(II) sulfate), the developed fungicide preparation can be successfully used instead of traditional Bordeaux mixture and in particular against the peach leaf curl.According to the results of field trials, effect, of developed silicon containing humic nutrient composition -“Si-humate” on experimental 2-year-old seedlings apples and peach is on the average 15–17% better than the control ones in terms of growth and development index. It should also be noted that no harmful diseases were found on the treated seedlings.The developed compositional formulations can be successfully used for integrated protection of plants against pests and diseases. Their use is absolutely safe for the human and the environment.
