  Certainly, I mean of extracts of plants in general. This wider concept, than plant essential oils, but basically there are no differences between the products. Any case we deal with natural pesticides.

  Such examples set. Here the brightest. Azadirachtin A (azad, neem, salannin) - a potent tetranortriterpenoid botanical insecticide derived from tree Neem active against a wide range of insect pests. It also has some fungicidal properties (http://sitem.herts.ac.uk/aeru/footprint/en/Reports/46.htm). It is highly effective insecticide against a bug (I personally took part in its tests). Some natural extracts give rise to the whole new classes of pesticides, for example, fungicidу sorts strobilurin. The discovery of the strobilurin fungicides was inspired by a group of natural b-methoxyacrylates, the simplest of which are strobilurin A and oudemansin A (see article). Among other pesticides, which originate from natural fungicidal derivatives, the strobilurin class of compounds play an important role in an effective control of various types of plant pathogens (ascomycetes and basidiomycetes).

  All sulfonylurea herbicides possess, have unique selectivity, a wide spectrum of action and a range of terms of entering (in the autumn, in the spring), sufficient activity at temperature more low 10°С. Therefore I have been a little surprised that sulfosulfuron does not work at temperature lower 15°С. 1. I Advise to carry out the analysis of preparation form and check decomposition of reactant substance and рН. Hydrolytic stability sulfosulfuron at 25°C: pH 4 - 7d, pH 5 - 48d, pH 7 - 168d, pH 9 - 156d. 2. Solubility sulfosulfuron in water is varied depending on рН of solution: 18mg/l (pH 5), 1627mg/l (рН 7) and 482mg/l (рН 9). Advise number 2: it is necessary to prepare a working solution especially using deionized water with рН 7. I hope, could help. I wait for result.
