MicroMaster OMRI-Approved Treatment

MicroMaster is a humic acid seed treatment that has the ability to manipulate hydrogen molecules in order to better utilize their use in the plants early season growth and development. MicroMaster has the ability to isolate a hydrogen ion. Through that isolation, the humic acid seed treatment can change the polarity of that ion from positive to negative or negative to positive to match what the soil needs. This process is specifically called electrostatic attraction. It attracts nutrients and facilitates the uptake that a plant needs to succeed in its early growth stages. This type of electrostatic attraction also allows for less leaching in the soil which offers the plant the most readily available nutrients in the soil. It also uses complex chelation to dissolve and bind minerals. This process works hand in hand with electrostatic attraction to allow the plant to take up the proper nutrients at the best time to give our organic hybrids an enhanced opportunity at early growth. Increased early season emergence and vigor is extremely important in producing a strong organic crop.

MaximQuattro Fungicide

  • Unmatched broad-spectrum protection against seed- and soil-borne diseases.
  • As a fourth mode of action, thiabendazole enhances the proven protection of Maxim 4FS, Apron XL and Dynasty.
  • Best-in-class systemic protection against Fusarium species including Fusarium graminearum and Fusarium verticillioides.
  • Helps clean up seed surface and internal pathogens.
  • Produces stronger, healthier plants by protecting seedlings.
  • Helps increase nematicidal activity when used as a component of Avicta Complete Corn

Enhanced Protection Against Nematodes: Though microscopic and difficult to detect, nematodes can cause significant damage to the crops they infect. By feeding in or on plant roots, nematodes create an entry point allowing viruses and bacteria to attack the root and weaken the plant. Even if there are no visual symptoms, yield and profit potential may be hindered from nematode damage. Studies show that Maxim Quattro, when used as a component of Avicta Complete Corn, may help increase activity on nematodes and therefore help increase yield potential.

By creating an initial zone of defense, Maxim Quattro helps strengthen the seedling which leads to a healthier plant throughout the season. Together, the four active ingredients – thiabendazole, azoxystrobin, mefenoxam and fludioxonil – provide unsurpassed protection against corn seed- and soil-borne diseases. Thiabendazole offers best-in-class Fusarium protection, specifically against Fusarium verticillioides. Thiabendazole improves an already successful seed treatment portfolio by offering a new mode of action with systemic protection from day one. Maxim Quattro helps clean up surface and internal pathogens on or in the seed, resulting in a stronger plant from the inside out.

Protect Against Fusarium for a Healthier Crop: Fusarium is a genus of harmful fungi Seed treatment At A Glance Contains: MaximQuattro Fungicide Vibrance Fungicide Storicide Insecticide Storage Treatment Protection against Rhizoctonia, Fusarium, and Nematodes found in plants. Distributed through the soil, it enters through the roots or at the soil line, causing plants to wilt and decay. Fusarium can inflict severe damage not only to the crop, but also to the field. Fludioxonil promotes healthy plants from the very beginning by offering proven protection against Fusarium graminearum, one of the most common types of Fusarium. Thiabendazole reduces infection of a lesser-known, but equally damaging Fusarium species – Fusarium verticillioides. With the added protection, roots remain unharmed and develop into vigorous, healthy plants.

Mycotoxins: Fusarium verticillioides may cause severe damage to plants by infecting the roots, but it can also produce mycotoxins. If mycotoxin levels increase, they can be very harmful to crop quality. Protecting corn plants against Fusarium verticillioides using a seed treatment fungicide such as Maxim Quattro may decrease the threat of mycotoxins and their harmful side effects.

Vibrance Fungicide

Vibrance® seed treatment fungicide is formulated to boost a crop’s rooting power by delivering enhanced disease protection that leads to strong root systems and improved crop performance in more than 18 different crops.

Rhizobium inoculant for legumes, physical seed protection, moisture absorption aid, and fungicide retention. A key to any successful establishment and early seed development is moisture. Nitro-Coat® is both naturally hydrophobic and hydroscopic. The protective coating prevents seeds from suddenly germinating during a brief single moisture event, while at the same time naturally absorbing water during sufficient moisture events and helps attract soil moisture to the seed for better stand establishment. With Nitro-Coat® each seed is inoculated with the correct Rhizobium strains and coated through a proven process that ensures a very high level of successful inoculation for each plant.

For both conventional and OMRI-approved grasses and legumes, these coatings improve the seed germination, early growth, and lifelong stand. The Super Hydrating polymer holds water around the seed and keeps the micronutrients in concentration around the growing root, giving maximum benefit for germination and early growth. Larger seed size helps with more even seed distribution and improved seed to soil contact.

Myco Seed Treat

  • Phosphorus quickens root hair development. Healthier roots mean more vigorous and competitive plant growth.
  • Slow-release nitrogen feeds new shoots and leaves.
Yellow Jacket

May be included in “CT” treatment – Barenbrug products only Barenbrug color logo

Yellow Jacket is like having a sponge around each and every seed. Once water is applied, the coating holds moisture and other nutrients around the seed – making them available as needed for germination and establishment. Without coating, the water simply passes the seed, allowing it to dry out, and resulting in more frequent watering needs and increased labor and expense.

This spongy layer has additional benefits as well. Yellow Jacket coating increases the density of very light, small bentgrass seed. This makes seeding easier, more accurate and also allows for a more uniform distribution pattern when applied with a seed spreader. Seed stays where it falls due to the extra weight and size and is much more easily seen. When overseeded, the coated seed will move down in the turf faster and easier. Another tremendous benefit is that Yellow Jacket coated bentgrass has enhanced disease protection, unlike uncoated seed.

All these benefits are due in large part to a key component of Yellow Jacket – a super absorbent technology that can hold 600 times its own weight in water. University trials show that super-absorbants can absorb and hold fungicides and protect seedlings up to three weeks after seeding. Fungicide on uncoated seed washes off, quickly limiting their benefit.

The Yellow Jacket formulation also contains Apron XL® (metalaxyl). A new technology turf fungicide that specifically helps prevent Pythium infestation in newly seeded areas, Apron XL preserves root development and significantly increases the survival rate of seedling turf during higher temperatures.

Research trials at the University of New Mexico also show that Yellow Jacket enhanced seed establishes faster and requires less water. Yellow Jacket simultaneously helps the seed thrive while conserving water.
