YOU SHOULD ADD ADJUVANT to the mixture in the case of:

  • ASSORTED working mixture
  • UNSATISFACTORY DISTRIBUTION of mixture on the leaf
  • ASSORTED DISTRIBUTION of products in the upper layer of soil
  • EVAPORATION and too fast DRYING-OUT of the application surface
  • WASHOUT in the soil and DROPPING-OUT of the leaf
  • BAD PENETRATION of products into the plant
  • ATTRITION BY WIND during the application

рН of water– WHY IT IS IMPORTANT?

If рН of water is more than 7 – the active substance degrades and its efficiency decreases due to ALKALIC HYDROLYSIS. The reaction rate is measured by the half-decay period, which is the time at which the efficiency of the mixture is reduced by 50%. The alkalinity, or the pH of the water, is a balance or the imbalance of Н+ and ОН- ions.

EXAMPLE

Fungicide - SDHI
Chemical group- carboxamide

Acid environment (<6,5)

рН 5

Half-decay period – >100 days

Neutral environment (6,5-7)

рН 7

Half-decay period – 5 hours

Alkalic environment (>7)

рН 9

Half-decay period – 1 hour

Water HARDNESS

Water hardness NEGATIVELY affects some of pesticides. Negatively charged molecules of pesticide are attached to positively charged molecules of IRON, CALCIUM and MAGNESIUM in hard water. When linked to pesticides, these minerals create molecules which can not reach the main goal (the fight against harmful organisms), since they start to act much slower, or precipitate in a mixture.

MAIN GOAL– TO IMPROVE THE QUALITY OF APPLICATION

  • improvement of quality of the working mixture
  • improving the structure of the jets
  • reduction in the amount of fine-fractional drops
  • equalize the size of the drops to the homogeneous
  • avoiding the attribution of the wind
  • better distribution on the surface
  • better penetration into the plant
  • maintaining the properties of the working mixture
  • reduction of washout
  • better maintenance of the mixture in the organs of the plant
