Dosages and application method:
Buneba L can be applied during the entire growth cycle, whenever it is required.
Standard dose is 1Lt/Ha. Repeating it on a 15 days interval until plant stress is over.
In case of adverse weather, or chemical damages, interval can be reduced.
Buneba L can be mixed with any fertilizer, fungicide or pesticide. That will facilitate its action by the penetrating effect in Buneba L’s formula.
Non-Toxic, Non-Flammable product.
SILICON’S ROLE IN PLANT NUTRITION
Plants absorb silicon from the soil solution in the form of monosilicic acid, also called orthosilicic acid [H4SiO4].
Optimization of silicon nutrition results in increased mass and volume of roots, giving increased total and adsorbing surfaces.
Silicon plays an important role in fruit and grain formation and quality.
Numerous field experiments under different soil and climatic conditions and with various plants clearly demonstrated the benefits of application of silicon fertilizer for crop productivity and crop quality.
Silicon has been found to suppress many plant diseases and insect attacks.
The effect of silicon on plant resistance to pests is considered to be due either to accumulation of absorbed silicon in the epidermal tissue or expression of pathogensis-induced host-defense responses.
Research also points to the role of silicon in plants as being active and suggests that the element might be a signal for inducing defense reactions to plant diseases. Silicon has been demonstrated to stimulate chitinase activity and rapid activation of peroxidases and polyphenoxidases after fungal infection.
More recently, flavonoids and momilactone phytoalexins were found to be produced in both dicots and monocots, respectively, and these antifungal compounds appear to be playing an active role in plant disease suppression.
Silicon deposits in cell walls of xylem vessels prevent compression of the vessels under conditions of high transpiration caused by drought or heat stress. The silicon-cellulose membrane in epidermal tissue also protects plants against excessive loss of water by transpiration. This action occurs owing to a reduction in the diameter of stomatal pores and, consequently, a reduction in leaf transpiration.
ZINC’S ROLE IN PLANT NUTRITION
symbol: Zn; available to plants as Zn++
- Zn is required in the synthesis of tryptophan, which in turn is necessary for the formation of indole acetic acid in plants.
- Zn is an essential component of several metallo-enzymes in plants (variety dehydorgenases) and therefore is necessary for several differerent function in plant metabolism.
- The enzyme carbonic anhydrase is specifically activated by Zn.
- Zn has a role in RNA and protein synthesis.
Zinc the regulator
Zinc was found to have a number of different effects as in some cases it decreased, in others increased, and in others had no effect on plant susceptibility to disease.
In most cases, the application of Zn reduces disease severity, which could be because of the toxic effect of Zn on the pathogen directly and not through the plant’s metabolism.
Zinc plays an important role in protein and starch synthesis, and therefore a low zinc concentration induces accumulation of amino acids and reducing sugars in plant tissue. As an activator of Cu/Zn- SOD, Zn is involved in membrane protection against oxidative damage through the detoxification of superoxide radicals (Cakmak 2000). Impairments in membrane structure caused by free radicals lead to increased membrane leakage of low-molecular-weight compounds, the presence of which favors pathogenesis. Application of Zn to the soil reduces infections by Fusarium graminearum and root rot diseases, e.g., caused by G. graminis (Sacc.) in wheat.
