Presowing seed treatment |
|
These recommendations are based on 'The list of pesticides allowed for use
in Russian Federation', regulations issued by The Institute of Plant Protection
Russ. Acad. Agric. Sci., and other Russian authorities. Therefore, the recommendations
are applicable in Russia only, and may be partially or entirely changed in other
countries, depending on requirements of local laws and regulations.
Purpose. Presowing seed treatment of cereals
(wheat, rye, barley, oat, rice) with Albit provides plant protection against
root rots, stem helminthosporioses and other diseases, noticeably increases yield and yield
quality, total and productive tillering, germination and germination power
(up to 10-15%); improves mineral nutrients uptake, winter survivability (for winter crops),
heat, frost, moisture and drought resistance. Earlier and accelerated development of rootage
due to Albit treatments reduces susceptibility to root rots and diseases, and creates a basis
for high yield. Presowing seed treatment is crucial for sunflower, buckwheat, maize,
pea and other legumes. For example, disease protection of sunflower (against head
gray mould blight and watery soft rot) and pea (root rots) is almost completely attributed
to presowing seed treatments. Following foliar sprayings with Albit of cultures mentioned
above provides pronounced effect solely in case of preliminary seed treatment.
Procedure of working solution preparation. Albit should
be thoroughly shaken (mixed) before use. Albit is a high-concentrated
biostimulant, therefore it is applied diluted with water (working solution). For example,
presowing seed treatment of 1 tonne of grain requires 40 ml of the biostimulant diluted
in 10-15 litres of water. To dilute, ¼ of necessary amount of water should be mixed with
Albit in tank, and then the rest of water must be added. Treatment is performed in
specialized seed treatment machines or manually. Working solution must be used out
within 24 hours after preparation. To increase the effect of Albit,
adjuvant (5-10% whey, Na-CMC, 0.2 kg/tonne of seeds) may be added to working solution.
Presowing seed treatment, combination with fungicides. Before
treatment with Albit, phytopathological examination of seeds must be carried out. Presowing seed
treatment with Albit only can be performed if infestation of seeds with complex of diseases is
not higher than 30% (low infestation level) and in absence of smut infections.
In case of moderate infestation of seeds (up to 10% of internal and 30-50% of
external infestation, 0.3-0.5% of loose smut infestation and up to 500 spores of stinking smut
per grain) it is reasonable to use Albit with minimal recommended or with halved dose of chemical
fungicide. In case of high infestation (more than 10% of internal and 50% of external infestation,
0.5-2% of loose smut infestation and 500-2500 spores of stinking smut per grain), seeds must
be treated with combination of Albit and full dose of chemical fungicide. Addition of Albit
to flutriafol-containing fungicides might accelerate ripening of cereals by 3-12 days, increase
yield, and control of diseases during whole vegetation period. Albit should not be used on seeds that are pelleted or pre-treated with pesticides.
Storage of treated seeds. Albit-treated seeds
should be stored in dark, at temperature below +20°C, under ventilation. It
is recommended to saw seeds within 24 hours after treatment (except
sunflower seeds). Otherwise, Albit might be decomposed by native microbial
community of seeds, that will result in loss of efficiency. Joint treatment
of seeds with Albit and chemical fungicide can prolong storage period of treated
seeds up to 1 month, since in that case chemical pesticide serves as a preservative
for Albit.
Results of seed treatment with Albit you can see in the following
