Albit may be applied in a mixture with other biological products and plant
growth regulators. In all field trials conducted to date, the treatment of
plants with such mixtures showed a significant positive effect. However, these
combinations depending on product, may demonstrate both a synergistic effect
(mutual enhancement) and a mutual decrease of activity. Biological products
and plant growth regulators may be divided into 2 groups based on the effectiveness
of combination with Albit.
The first group includes products that enhances
effect of Albit. First of all, it is humates. Humates are polygenic group,
their composition and properties depend on method of production. Therefore,
Albit is differently combined with various humates. The effectiveness of the
combination with Albit increases in the range:
sodium humates -> potassium humates -> lignohumate
In our country, lignohumate is registered as an agrochemical product. For
more detailed information about combined application of Albit with lignohumate,
please see “Combination with fertilizers”.
The maximal absolute yield increase of grain crops was obtained
in combined application of Albit (1.5 t/ha) with humates (“Plemzavod named after
V.I. Chapaev”, Krasnodar Territory, 2003). According to trials of Krasnodar Territory,
combined application of Albit with humates gave a stable increase of gluten
content in winter wheat (5.3%). Separate application of these products did not
give the such positive effect. According to data of “Ecology LLC” (farms of
Tselinsky district, Rostov region, 2001-2003), pre-sowing seed treatment of winter
wheat was optimal in the following composition: Albit 40 g/t + product based
on thiabendazole + flutriafol 1 L/t + potassium humate 200 g/t + adjuvants. This
composition allows to significantly improve overwintering of plants, completely
get rid of root rots, rapidly increase the drought resistance of plants in spring
and summer, increase weight of plant roots in 2-4 times.
According to trials conducted on winter wheat var. Pobeda-50 at the
National Center for Grain named after P.P. Lukyanenko (2004), adding of Albit
to all tested varieties of humates during vegetative treatment
(potassium humate, potassium and sodium lignohumates, hydrohumate, peat oxidate)
provided yield increase 0.09–0.25 t/ha (3 t/ha was in the control) in comparison
with application of pure humates.
On sunflower, the maximal effect of Albit is observed either in variant with
seed treatment or in variant with spraying at the beginning of the
growing season. On the other hand, according to trials of Shakhtinsky
district of Rostov region (2005), humates showed visible growth-stimulating
effect in the second half of the growing season. Therefore,
for achievement the maximal effect on the plant culture, the following combination
of products seems to be optimal: presowing seed treatment with Albit (possibly
in combination with spraying at the stage of 4-7 true leaves) + treatment with
humates in the second half of the growing season.
There are few biological products enhancing the effect of Albit, since Albit
itself is a complex product that combines many components and have a lot of
useful functions. Therefore, it is unlikely that adding of extra components
to Albit may enhance its effect.
Effectiveness of combined application of Albit was shown not only with humates,
but also with Immunocytophyte, Chitosan and Krezacin. All these products have
a specific target of action. Albit as a plant growth regulator has a wide rang
of action: firstly, Albit “insures” these products in case of “failure to hit
the target”; secondly, Albit enhances their effect due to the action to other
targets. In field trials of Krasnodar Territory, the effectiveness of combined
application of Albit with complex microbial product EM was also shown.
The second group includes biological products whose combination
with Albit is ineffective. The fact is due to Albit already contains the corresponding
components and their extra addition does not lead to enhancement their action.
For example, Albit is poorly compatible with Silk, Novosil, Biosil, Terpenol
and other analogous products based on triterpene acids, because Albit contains
this active ingredient. Thus, adding of excess amount of triterpene acids leads
to decrease the effect.
In the field trial of Experimental-industrial economy Plemzavod “Kuban’” (Gulkevich
district of Krasnodar Territory, 2003), yield of soybean in control was 1,83
t/ha; in variant with product based on triterpenic acids – 0.31 t/ha; in variant
with only Albit application – 0.49 t/ha; in combined application of Albit with
the same product – 0.25 t/ha. The same results were shown in trials on sunflower
(“Plemzavod named after V.I. Chapaev”, Krasnodar Territory, 2003): in variant
with seed treatment, adding the another product based on triterpene acids to
Albit reduced the effect of Albit from 24 to 18.3%.
Combination of Albit with biological products based on living microorganisms (based
on genera Agrobacterium, Arthrobacter, Azospirillum, Bacillus, Beauveria,
Burkholderia, Chaetomium, Flavobacterium, Penicillium, Pseudomonas, Serratia,
Streptomyces, etc.) also give low results. Microorganisms in these products
prefer to use Albit as an easy accessible substrate for growth, instead of
developing with using inaccessible nutrient resources of the soil, plant exudates
or pathogenic microorganisms (hyperparasitism). As a result, the effectiveness
of Albit is reduced.
Products based on spore-forming bacilli of Bacillus subtilis (for
example, Phytosporin) are exception. Microorganisms in these products are in
a spore form and cannot quickly utilize Albit. When spores of B. subtilis germinate,
Albit due to the effect on the soil microbial community have
time to create the most favorable conditions for development of these bacteria.
For example, Albit is able to increase the abundance of spore bacteria on barley
roots in 9 times to control (Table 2). When B. subtilis is
additionally applied in combination with Albit, this allows to fully reveal
their potential in the ideal conditions. For example, the yield of winter wheat
var. Vassa in variant with product based on B. subtilis was
5.2 t/ha; in variant with product based on B. subtilis and Albit –
5.77 t/ha (yield increase 0.57 t/ha) (“Plezavod named after V.I. Chapaev”,
Krasnodar Territory, 2015). The same results were obtained in Bulgaria, Novosibirsk
and Tyumen regions.
