The Grigg Brothers flagship protocol is the Foliar Tournament Program.
This mix supplies all nutrients needed for plant growth including those critical for photosynthesis. It also supplies a spreading agent for better leaf contact, a water buffer agent to bring the pH of the mix to the correct level for plant uptake and also contains biostimulants, sugars and amino acids. Simply put, it has No Equal! Click on "Foliar Tournament Program" from the expanded menu on the left to read all about it.
Instructions & Tips For All Applications:
- Grigg Brothers Tru-Foliar™ programs are a complete mix containing amino acids, organic acids and complex sugars. No other brand of products are required or have been scientifically proven to enhance the performance of any Grigg Brothers foliar programs.
- RATES: The following programs are suggested at rates per 1,000 Ft2, mixed with 1-2 gallons of water and foliar applied.
- VERY IMPORTANT: Products are designed to be foliar applied and foliar absorbed, therefore it is essential for maximum performance that the application is allowed to dry on the plant for 6 hours before watering.
- SURFACTANT: The use of Grigg Brothers Ultraplex™, is recommended with all applications to enhance spreadability of our products. Ultraplex™ is designed specifically to work with Grigg Brothers products and all others on the market today. Other non-ionic surfactants may be used. Ultraplex™ should be added at the rate of 3 fl.oz. per 1,000 Ft2 with all foliar applications.
- Grigg Brothers products exhibit a high degree of compatibility and may be mixed with Primo MAXX® as well as foliar applied fungicides, insecticides and herbicides that do not need watered in. When mixing with herbicides consider using the lowest label rate as Grigg Brothers products may enhance the uptake of the herbicide.
- NOTE: Products should be applied at one or two week intervals typically, or as determined by the golf course superintendent.
- Grigg Brothers chelated micro-nutrients can be added based as dictated by soil and tissue tests. The rates for added micro-nutrients typically range from 1-3 fl oz Per 1,000 Ft2 severe deficiency 6 fl oz per 1,000 Ft2
- OPTION: Prescription foliars can be formulated by the Superintendent based on tissue test results, with Grigg Brothers individual products and experience and technical assistance from Grigg Brothers.
- THE FOLLOWING SAMPLE PROGRAMS are suggested programs that have shown good results in previous years and should be considered. The programs can be adjusted to your specific needs, and your microclimate. Products can be applied up to one day prior to events to finish your preparations as a final cosmetic adjustment. The products will be effective and noticeable because of their rapid response.
- SOILS BIO-AMENDMENT PROGRAM: For sand based greens, use 1 Gallon of Bio Blend™ and 4 Gallons of Carboplex™ applied monthly and lightly watered in. For soil based greens use 1/2 Gallon of Bio Blend™ and 2 1/2 Gallons of Carboplex™. This program can be rotated with the foliar program once per month
TOURNAMENT PROGRAM
Generally speaking tournament preparation means a low height of cut to produce faster greens. The challenge to superintendents, who maintain tournament conditions, whether for a special event or year around, is to keep density and quality up while producing those desire fast greens. Tournament mowing heights typically are below .125 inches on both cool and warm season turf. Often during a special event greens are double cut in the morning and may be cut again in the evening. As mowing heights come down root growth ceases.
During photosynthesis; sunlight, carbon dioxide and water through the action of the chloroplasts and chlorophyll yield carbohydrates, oxygen and water. These carbohydrates are both utilized by the plant to sustain growth and life functions as well as be stored in the roots for reserve.
Roots are not photosynthetic and are 100% dependent on the photosynthetic energy captured in the leaves and shoots. The amount of energy captured depends on such things as the duration of light, the extent of stress, and the amount of leaf surface. Superintendents in order to satisfy the wants of their golfers for green speed during tournament play or at all times, simply cut their greens so low and so often that there is very limited leaf surface to photosynthesize.
In an ordinary situation a turf plant will store ½ of all the carbohydrates produced in the root and utilize ½ for sustaining life functions. Around ½ of that carbohydrate reserve in the root is then excreted back into the rhizosphere as a microbial food substance called exudates. These exudates are a combination of protein, carbohydrates and sugars and these exudates sustain the life of the complex micro-community and the microbes in turn make nutrients in the soil available to the plant. This is the way Mother Nature intended to provide for the plants needs. A modern putting green mowed at 1/8 inch or less, regardless of if it is a warm or cool season grass, simple can not produce enough photosynthesis to make enough carbohydrates to go around. The turf is trying to survive and utilizes all the carbohydrates available to do just that - survive. The plant therefore does a poor job of storing any carbohydrate reserve in the root.
While the genetics of both the bentgrass and bermudagrass species vary, there are fertility practices that the golf course superintendents can adapt to help when the turf is being mowed so low. The health of turfgrass being cut so low will depend in large part on the management practices during this period of time.
One of those inputs is the nutrient level of the plant tissue. There are 13 essential nutrients required by all higher plants other than C, H & O2, which are provided by water and carbon dioxide. Plant health, growth, and development are dependent on all of these elements being present at optimum concentrations. Many scientists believe that plant growth and survival during periods of stress is dependent on these 13 elements being present at optimum concentrations.
In general the utilization level of Grigg Brothers foliar fertilization is very high, whereas common soil nutrient utilization even in the best conditions, including foliar applied but root uptake products, is very low. Roots only come in contact with a small percentage of the soil and combined with the fact that when soil temperatures are high or low, or soil pH is higher or lower than the optimum range the plant is then not always able to take up through the roots even those nutrients which are available in the soil. N, S, Fe, Mn, & Zn are critical nutrients needed for chlorophyll production and thus carbohydrate production. Calcium may also be in short supply as new root growth is restricted, even in a highly calcareous soil or when calcium is being supplied as a granular.
True foliar fertilization bypasses these problems as the applied nutrients are immediately available to the plant!
Grigg Brothers recommendation is to follow our tournament program:
Gary’s Green™ 4-7 oz / 1,000 ft2
Tuff Turf™ 3 oz / 1,000 ft2
Sili-Kal B™ 3 oz / 1,000 ft2
Ultra-Plex™ 2 oz / 1,000 ft2
(The Ultra-Plex™ can be increased if desired for enhanced color)
This mix supplies all nutrients needed for plant growth including those critical for photosynthesis. It also supplies a spreading agent for better leaf contact, a water buffer agent to bring the pH of the mix to the correct level for plant uptake and also contains biostimulants, sugars and amino acids. Both Tuff Turf™ and Sili-Kal B™ contain Silicon for added green speed. It is a complete mix and nothing else is required.
Annual Bluegrass and Bermudagrass will require the higher rates of Gary’s Green™ and during the summer months those with annual bluegrass greens will do better to substitute 6 oz per 1,000 ft² of P-K Plus™, which contains potassium phosphite, in place of the Tuff Turf™ for help with "summer Stress Syndrome".
Applications should be from one to two weeks apart. Add to that mix any other minor nutrients that you know are deficient in the plants based on a tissue or soil test.
We sincerely hope this letter will help provide you, the turf manager, with a better method of fertilization for tournament preparation. COOL SEASON PROTOCOLS
