On pea, Albit is applied
as antidote for decrease of side phytotoxic effect
of herbicides. In Russia, Albit is officially registered as a plant
growth regulator of pea. Albit increases field germination capacity,
accelerates plant growth and development, improves plant resistance to unfavorable
conditions of the environment, provides defense against plant diseases, increases
pea yield and improves the yield quality.
On pea, Albit has been tested since 2001 in field trials of All-Russia Research
Institute of Legumes and Groat Crops (Oryol oblast), All-Russia Institute of
Vegetable Selection and Seed Breeding (Moscow oblast) on var. Orlus, Truzhenik, Vega, Orlovchnin, Nord and
others. Albit is successfully used on peas in farms of Krasnodar krai, Tatarstan
Rebublic, Oryol, Tambov, Vladimir oblasts and also in other institutes and
farms.
One feed unit of pea contains more than 150 g of digestable protein, whereas
other forage crops (maize, barley, oat) contain less amount of digestable protein
– 59 g, 70 g, 83 g, respectively (animal nutrition standard – 110-120 g). High
nutritious value of pea makes it prospective culture. Treatment with Albit
is able to considerably increase yield of pea.
For example, in 2015 treatment with Albit increased yield of pea by 1.3 t/ha
(30% over control, Agroholding Kornev group). According to results of the trials,
treatment with Albit increased pea yield by 0.2 t/ha (12.8%
to control). Depending on year, variety and location of field trial, yield
increase varied from 0.1 to 0.62 t/ha. Yield of green biomass is also increased
averagely by 18.0%. According to results of All-Russia Institute of Vegetable
Selection and Seed Breeding, pea gives the highest yield increase in response
to Albit treatment among all other tested legume crops (pea, soybean, french
bean, lentil, fodder bean, lupine).
It is necessary to note that presowing seed treatment of pea with Albit is
efficient against root rots of different origin (Fusarium spp., Pythium
debaryanum Hesse, Rhizoctonia sp.), which cannot be
completely controlled by chemical protectants. The average Biological Efficiency
(BE) of Albit against rot rots of pea – 41.4%, maximal BE – 73%. This is equal
or even higher than BE of standard chemical protectant. Fungicidal activity
of Albit was observed at disease prevalence of 90-100% and disease development
of 25-61%. After foliar spraying with Albit, decreased by 50% infestation of
leaves by brown rust was observed.
Albit not only increases yield and protects against diseases, but also increases
field germination, germination energy of pea seeds (Fig. 1),
length of shoots and roots, the number of productive nodes, activity of flowering,
the number of pods per plant, seeds per plant, decreases accumulation of radionuclides
in crop.

Application recommendations. It is recommended presowing
seed treatment (50 mL/t) and foliar spraying at
the budding stage (30 mL/hà, ÂBCH 50-60). To decrease infestation of plants
with root rots, one presowing treatment is sufficient; extra foliar spraying
should be applied to obtain maximal yield. Albit may be applied as antidote
in tank mix with herbicides according to their perspective recommendations.
Foliar spraying with Albit is recommended to be combined with scheduled insecticide
(based on alfa-cipermethrin, dimetoate and others) and herbicide (based
on imazamox, bentazone + 2-methyl-4-chlorophenoxyacetic acid and others) treatments
to relieve toxical influence of pesticides and obtain increased yield. In these
cases, application schedule of Albit can be changed according to recommendations
of corresponding pesticides.
In the farm Agro-company Kuteminskaya (Tatarstan, 2010), in the conditions
of extreme drought (soil temperature was +75°C, air +32°C), peas were treated
before planting with tank mixture of Albit (70 mL/ha) + fungicide. Early ripening
of peas was observed in variant with Albit treatment (by 7-10 days earlier
than in control). This promoted to harvesting by direct combining. The yield
of pea was 1.7 t/ha, the difference with control was 0.51 t/ha. In addition,
on a small plot of the field due to a poorly washed sprayer, pea plants obtained
herbicide burn and severe stress: yellowing of leaves and general suprssion
of plants were observed. Albit application in a dose of 100 mL/ha removed
this problem.
In 2009, the same incident was observed in Tatarstan Republic. Due to faultiness
of sprayers, increased concentration of herbicide (based on imazethapyr + chlorimuron-ethyl)
was applied on pea var. Truzhenik. As a result, plants were stressed,
their growth was stopped; dropping of tendrils, side shoots, leaves, and also
chlorosis and albication of leaves, loss of total turgor were observed. Plants
recovered only after Albit application. 3 days after herbicide application,
plants were treated with Albit (40 mL/hà). After that, their normal growth
was recovered. On photo you can see results of Albit application on pea in
Tatarstan Republic (photo was made 1 week after Albit application). Anti-stress
effect of Albit is visible on Fig. 2 (top: left – control without Albit treatment,
right – field was treated with Albit). On Fig. 2 (bottom) you can see pea plants
(left – control plant damaged by herbicide, right – plant after spraying with
Albit). In variant with Albit yield was 2 t/hà. Application of Albit allowed
to increase yield of pea by 15%. In fact, it is crop preserved from herbicide
stress.

In Agroholding Kornev group of Tambov oblast, Albit was applied on pea var. Roket for
removing of stress after treatment with herbicide based on imazamox (60 mL/tà
for foliar spraying, application rate of working solution 1.2 L/20 hà, 2015,
Fig. 3).

variant with Albit (Agroholding Kornev group, Tambov oblast, 2015)
As a result, yield increase of pea after Albit application was 1.3 t/ha (30%).
On pea, Albit demonstrated a high economical efficiency.
1 litre of Albit is applied for treatment of 25 ha and gives extra yield ca.
5.1 tonns of pea.
Results of long-term practical application of Albit on green pea in
Krasnodar krai confirmed that this culture gives even higher yield increase
in response to Albit than fodder pea. Application rates and methods of treatment
of green pea are the same, but economical effectiveness of Albit treatments
is considerably higher due to high cost of final production.

performance of Albit on pea, available in
English. For all available
