ORGANO-MINERAL FERTILIZER LURS GROPERLIN B
The organo-mineral fertilizer LURS® groperlin B is intended for the prevention and elimination of symptoms of boron starvation in sensitive to boron deficiency field crops, fruit, berries and vegetables. It has additional properties of a surfactant (wetting agent) and growth stimulant in the form of a wettable powder. It dissolves well in a large volume of water. The formulation has a high concentration of boron in the form of polyborates.
LURS® groperlin B contains a special anionic surface-active complex groperlin with a stimulating effect for the best distribution of the tank mixture over the leaf surface and better fixation of active substances. The stimulating effect is achieved due to the fact that groperlin forms a complex organic compound with boron in water, which contributes to better assimilation of boron by plants and additionally stimulates their vital processes.
Unlike many boron fertilizers, which when dissolved in water can significantly increase the hydrogen index, bringing it to a critical value, thus reducing the efficiency of pesticide application, LURS® groperlin B decreases the acidity of the solution if the water indicators are alkaline. Thus, the formulation eliminates the possibility of half-decomposition of plant protection products sensitive to alkaline environments.
Application: in tank mixtures LURS® groperlin B is added directly to the sprayer tank first. It can be used together with pesticides, growth regulators, micronutrients and biological products.*
EFFECT OF LURS® groperlin B ON THE CHANGE IN PH OF THE WORKING SOLUTION**
| Product | Amount of formulation per 250 L of water (tank mixture), kg | pH value, units |
| LURS® groperlin B | 0 | 8.0 |
| 0.5 | 6.9 | |
| 1 | 6.7 | |

- boron is in a form easily accessible to plants;
- it quickly eliminates hidden and obvious boron deficiency;
- contains an organic surface-active complex groperlin with a stimulating effect;
- improves pollination and fruit setting;
improves the development of winter rapeseed plants in the autumn;
increases the oil content in seeds of oilseed crops;
creates an optimal pH level for appliation of pesticides (in the range of 6.5-7.5).
It is recommended for use in conjunction with VIMPEL 2® plant growth stimulant.
