- General Information
OROBAC™ 100 produces phytohormones stimulating root growth for enhanced nutrient uptake, fostering the growth of a robust beneficial microbial colony in the soil, leading to improved tolerance to abiotic stress conditions. OROBAC 100 has been shown to be able to increase plants resistance against many phytopathogenic organisms.
Microbes applied to soils with a high soil organic carbon (SOC) content will multiply and remain active for many years. However, if the soil is exposed as a result of being turned over during plowing, the microbial population will be reduced. Hence OROBAC should be applied every season to fields with annual crops. Similarly, regular applications on soils with low SOC are necessary.
Conventional agricultural practices unfortunately often have a negative effect on the microbial population and regular OROBAC application will help to restore the balance.
The spores are not very sensitive to UV radiation although it is not desirable to leave an opened product container in the sun for an extended period.
Applications & Uses
- Markets
- Mode Of Action
The PGPR Bacillus spp. within OROBAC 100 are endospores (extremely resistant, dormant cell structures) that are activated by the plant exudates in the rhizosphere and germinate to grow out into fully functioning cells. These produce a wide variety of extra-cellular enzymes such as amylase, cellulase, protease, urease, xylanase, etc. which mineralize inorganic nutrients and convert carbon substrate into plant-available forms.
The rhizosphere is a rich source of plant exudates such as sugar, amino acids, fatty acids, etc. The rhizobacteria utilize them as a source of carbon and energy and in turn, promote and protect plant growth. This results in increased vigor, faster germination, greater root system development and consequently, increased yield.
The PGPR Bacillus spp. also produces a wide range of phytohormones that coordinate cellular activities, such as indole acetic acid (IAA), cytokinins, auxins, gibberellins and abscisic acid. The PGPR within OROBAC 100 grows in the roots of plants and protects the host plant by activating the inherent immune system of the plant.
- Application Rate & Timing
Crop Dosage Timing Placement Row crops and cereals 1L/ha At planting In furrow as close to the seed as possible Vegetables 2 x 1 L/ha At planting, One month later
In furrow close to the seed or transplant roots Via fertigation system in shallow irrigation to target active root zone Tree crops 3 x 1 L/ha At first root flush, Mid spring, Late spring Via fertigation in shallow irrigation to target active root zone Vines & berries 3 x 1 L/ha Budburst, 20 cm shoot growth, Flowering Via fertigation in shallow irrigation to target active root zone Ornamental plants 2 x 1 L/ha At planting, One month later In furrow close to the seed or transplant roots. Via fertigation system in shallow irrigation to target active root zone Potatoes 2X500ml/ha At planting, One month later In furrow close to the seed. Via fertigation system in shallow irrigation to target active root zone - Mode Of Application
OROBAC is in spore form and can be mixed and applied with most common liquid planting fertilizers without problem. However, do not leave the mixture standing in the tank overnight. If planting with solid fertilizer, it is best to apply OROBAC in the furrow via a liquid inoculation tank on the planter. Alternatively, application can be made by making a suspension in a separate tank and applying it through the irrigation system. Also boom application can be made. Product landing on foliage will not do any damage to the leaves but will be inactivated due to the exposure to the sun. OROBAC should be applied to the soil with sufficient water to allow it to soak in. The formulated product contains spores of the Bacillus spp. which are very resistant structures, so the risk of being damaged by other agricultural products is really low.
- Phytotoxicity
OROBAC 100 showed no phytotoxicity at doses and recommendations indicated on the label. In view of the continuing introduction of new varieties of vegetables and crops, it is nevertheless desirable to evaluate the effect of OROBAC 100 on small surfaces before applying on large scale.
- Further Recommendations
- Agitate content well before use as natural settling of spores may occur. Stir the content of the tank before application.
- OROBAC 100 should be applied directly in-furrow or with irrigation water.
- OROBAC is in spore form and can be mixed and applied with the most common liquid planting fertilizers without a problem. However, do not leave the mixture standing in the tank overnight. If planting with solid fertilizer, it is best to apply OROBAC in the furrow via a liquid inoculation tank on the planter.
- Do not exceed the recommended application rates.
- OROBAC 100 can be applied by direct boom sprayer onto the berm in an orchard situation but should be washed in by micro- or overhead irrigation shortly after application.
- OROBAC 100 requires a minimum of about 6 hours after application to colonize the roots. Avoid heavy irrigation for 1 - 2 days after application to allow time for root colonization.
- Where possible, apply OROBAC 100 separately. Nevertheless, OROBAC 100 is compatible with most fertilizers and plant protection products. Once mixed with other products, it should be applied within 4 to 6 hours. Spore counts start to decrease at a pH below 2. DO NOT MIX with Copper fungicides.
- OROBAC 100 should not be applied before soil fumigation. Apply at least 15 days after fumigation.
- This formulation is for soil application – not recommended for foliar application.
Regulatory & Compliance
- Classification
- P102 - Keep out of reach of children.
- P103 - Read label before use.
Storage & Handling
- Storage Conditions & Shelf Life
- No special precautions are necessary during storage.
- OROBAC 100 is an endospore-based microbial product and there is no need for refrigeration if sealed. If stored in cool ambient temperatures and dry conditions (Preferably between 4 - 30 °C), shelf-life of 18 months from manufacturing date can be expected. Use complete contents as soon as possible after opening, to avoid deterioration and contamination
