A talc-based enzyme seed treatment applied directly to seeds at planting or to roots when transplanted

Chandler Dry Seed Treat enhances the biological processes that control plant germination and early root development. We typically see 1-2 days faster emergence plus higher germination rates to help reduced seed costs. Treated plants have deeper root systems that increase nutrient and water uptake, plants have higher plant sugar content and are less susceptibility to drought, insects, and diseases. Dry Seed Treat may be used in place of talc in planters and other seeding equipment.

How does Dry Seed Treat work?

Chandler Dry Seed Treat is a talc-like powder that is applied directly on the seed at planting time. The talc carrier helps the treatment to easily adhere to the seed coat and also provides lubrication for finger and air planter mechanisms. The product contains micronutrients and naturally occurring enzymes, proteins, and amino acids that enhance the germination process and provide an early source of nutrients for the plant.

The result is faster seedling emergence, higher germination rates and more vigorous, earlier plant growth. As the emerged plant grows, Dry Seed Treat continues to work by enhancing plant root development (including nodulation in soybeans and other legumes), nutrient uptake and plant growth. At harvest, Dry Seed Treat promotes faster maturity and dry-down, higher yields and test weight and less lodging.

Dry Seed Treat is also available in liquid form for use in liquid seed treatment applicators. It is non-toxic when used as recommended and may be combined with insecticides, fungicides and other seed treatments.

Why is plant sugar content important?

Chandler Dry Seed Treat also enhances plant sugar content, which is an important measure of plant health and yield potential. Although some people can judge sugar content by tasting the plant matter, the best way to measure sugar content is to use a refractometer. The plant sugar content is typically reported in percentages or brix, and higher brix counts indicate healthier plants. For a corn plant, the readings may range from 1 to 20 brix, and we should find higher readings as we move up the plant and closer to the ear.

Higher sugar content also indicates that the plant will tend to have fewer insect problems, especially with plant sugar content of 10 brix or more. Insects cannot digest sugars, so they will tend to stay away from healthy plants and attack weaker plants with low sugar content. For example, one of our long-time users was mowing and observed that the insects were eating the grass and weeds in the waterways but were not on the corn or bean plants. The treated corn and bean plants had higher sugar content and were not attractive to the insects.

What ingredients are in Dry Seed Treat?

Chandler Dry Seed Treat is unique among seed treatments because it is one of the few products that is all natural and completely non-toxic, and the main active ingredients are enzymes rather than live bacteria cultures or inoculants. We only require a small amount of an enzyme to initiate the germination process and achieve the stated product benefits, and enzymes are less sensitive to soil pH and other environmental conditions. So, enzyme-based seed treatments tend to have lower cost and work more consistently than other types of biological seed treatments. Other ingredients are embedded on the talc carrier along with the enzymes, and these compounds are intended to support early plant growth and feed the beneficial soil microbes that help to build the root system. These ingredients include:

  • Amino acids and B-complex vitamins
  • Trace amounts of several micronutrients, including calcium, magnesium, sulfur, boron, cobalt, iron, manganese, molybdenum and zinc

How do I apply Dry Seed Treat?

Dry Seed Treat may be used on any seed, and it may also be sprinkled on the roots of any plant or tree that is being transplanted to another location (for example, tomato plants). The recommended application rate for Dry Seed Treat is about 4 ounces per unit of most medium to large seeds (corn, soybeans, or wheat) and 8 ounces per unit of smaller seeds (alfalfa or grass).

For convenient field application, Chandler Dry Seed Treat can be dusted on and thoroughly mixed with the seed in the planter box or seed hopper. The product can be applied without special equipment or handling. (Application rate varies by crop and population or seeding rate.)

What results can I expect from Dry Seed Treat?

Dry Seed Treat provides 1-2 days faster emergence with up to 10 degrees frost tolerance, and a higher germination rate, for reduced seed costs. Plants have deeper root systems with more tap and feeder roots to reduce lodging and increase nutrient and water uptake. Wheat and other small grains have more tillers, and soybeans and other legumes have more nodules.

Plant sugar content is 30-40% higher to build yields and deter insects, and plants have better tolerance to stress from extreme temperatures, drought or diseases such as blight or Goss’s wilt. In addition, nodal filters in the stalk remain open and allow more water and nutrients to move within the plant, and plants dry down faster at harvest.

Product Benefits for Specific Crops Reported by Our Users:

  • Corn – treated fields average 2,000 more plants per acre than untreated fields planted at the same population rate, higher sugar content and fewer insect problems, average 2 pounds higher test weight, 3-5 points dryer at harvest and average yield gains of 5-10 BPA.
  • Soybeans – more healthy root nodules (for nitrogen fixation), higher test weights, better quality and average yield increases of 3-5 BPA.
  • Cereal grains – more stooling and thicker stand, more stems or stalks per crown, higher grain quality, better test weight and average yield increase of 6-12 BPA.
  • Alfalfa – reduce seeding rates 3-6 pounds per acre, more healthy root nodules, higher yields, better quality (higher protein and TDN) and reduced winter kill.

How much does Dry Seed Treat Cost?

The recommended application rate is 4 ounces per bag or bushel of seed (4-8 ounces for alfalfa seed), so the per-acre cost depends on the seeding rate for the crop. At the regular retail price of Chandler Dry Seed Treat, the per-acre cost of the product is:

  • Corn: $1.07 per acre at a plant population rate of 32,000 plants per acre (2.5 acres per bag)
  • Soybeans: $2.67 per acre
  • Alfalfa: $0.90 to $1.80 per acre
  • Wheat and small grains: $2.50 to $3.50 per acre

The per-acre cost is lower for product purchased during our Fall (September to October) and Spring Pre-Season (December to March) Discount Programs. All prices are subject to change without prior notice.
