Description

SYNERGISTIC COMPOSITION OF A BIOSTIMULANT AND GLYPHOSATE
FIELD OF THE INVENTION
This invention relates to a novel formulation for a yield enhancing crop spray treatment finding particular application in the treatment of maize.
BACKGROUND OF THE INVENTION
Glyphosate is well-known as a broad spectrum systemic herbicide particularly effective against annual broadleaf weeds and grasses which compete with commercial crops such as maize. It is absorbed through foliage and translocated to other growth points in the plant and acts by inhibiting the activity of an enzyme involved in the synthesis of aromatic amino acids including tyrosine, tryptophan and phenylanaline. Accordingly, glyphosate is not effective as a pre-emergence herbicide and is only effective on actively growing plants.
The disadvantage of glyphosate is that it can stress and adversely affect the growth of the crops it seeks to protect from weeds. This prompted the development of genetically-engineered glyphosate-resistant crops (often sold as ROUND-UP READY™).
However, weeds are increasingly developing resistance to glyphosate and the applicant sought to attempt to alleviate this by making use of glyphosate in combination with other herbicides to increase the efficacy. At the same time, the applicant sought to counter the adverse effects of glyphosate and partner herbicides on the yield of the crop.
This approach has previously not been adopted because of concerns that the efficacy of the glyphosate would be adversely affected.
It is there for an object of this invention to provide a novel combination of glyphosate with a plant growth stimulant to enhance both weed control performance and the growth of the crop. THE INVENTION
According to the invention, a crop treatment composition comprises a mixture of a herbicide and a plant growth stimulant.
In one form of the invention, the herbicide is a post-emergance herbicide and in particular, glyphosate.
In this form of the invention, the plant growth stimulant is of the type formulated to enhance vegetative development and / or stimulate the formation of root hair, particularly during the vegetative growth phase of a crop. In the preferred form, the plant growth stimulant optimizes root development of crops resulting in an increased absorption of nutritional elements.
In this form of the invention, the glyphosate is combined with the plant growth stimulant for use in post-emergence situations, and in particular a foliar applied nutritional product for use in post- emergance situations. One example of such a product is TURBOMAIZE™.
In this form, the crop treatment composition of the invention may be used with maize and in particular, glyphosate tolerant maize varieties.
In an alternative form of the invention, a pre-emergence herbicide is combined with a plant growth stimulant formulated to stimulate root growth during the first crucial weeks following transplanting - i.e. in the vegetative growth phase.
In this form of the invention, the pre-emergance herbicide is combined with the plant growth stimulant PLANTSTART™.
In this form of the invention, the crop treatment composition may be used with maize, drybeans, soyabeans, sunflower and wheat.
In a further preferred form of the invention, a nutritional composition is added to the combination of pre-emergence herbicide and the plant growth stimulant. The addition of the nutritional component to a tank mix of pre-emergence herbicide and a plant growth stimulant is convenient and enables the farmer to reduce the number of sprays carried out. One of the advantages of the crop spray treatment of the invention, other than improved efficacy of the glyphosate (i.e. improved crop protection by improved weed control) and enhanced crop growth (yield), is the cost saving occasioned by being able to carry out a single spray treatment, rather than separate sprays for both crop protection and growth enhancement/ yield improvement.
EXAMPLES
Example 1 : glyphosate and TURBOMAIZE™
Trials were carried out in which the applicant's plant growth stimulant TURBOMAIZE™ was mixed with a tank mix of glyphosate such that in most cases 31/ ha of TURBOMAIZE™ and in another case 4i/ha of TURBOMAIZE™ and the corresponding recommended volume of glyphosate tank mix were applied to 6ha blocks in maize fields. Three reps were harvested in the treated areas and 1 rep of the untreated area on each side of the treated area. An average yield for the treated and untreated areas was then calculated.
Ammonium sulfate in the recommended concentration for the particular maize fields (as recommended by the chemical agent).
Sprayfilm 10 was used as a sticker/ wetting agent.
Between 100000 and 150000 litres of water was applied during irrigation. This application was done with tractor or self-propelled sprayers. It was not done through an irrigation system. Water quantity was 200 It/ha.
CONTROL
The control crop was sprayed with a tank mix containing glyphosate but no TURBOMAIZE™. The following results and observations were made:
1. No visual response within the first 8 days after application.
2. Small vegetative visual response after 14 days, but noticeable improvement in root growth.
3. At harvesting it was noticed that greater numbers of cobs, better filled cobs, larger cobs and better quality grain (visual) was found in the treated crop versus the control. Growth Stage of
Trials Input Application Yield Control Yield
TurboMaize™ 3 It/ha 6,3
1 Glyphosate V5-V6 6,8 +500kg/ha
TurboMaize™ 3 It/ha 6, 1
2 Glyphosate V5-V6 6,7 +600kg/ha
TurboMaize™ 3 It/ha 5,7
3 Glyphosate V10-V12 6, 1 +400/kg/ha
TurboMaize™ 3 It/ha 7,5
4 Glyphosate V8-V10 7,9 +400/kg/ha
TurboMaize™ 4 It/ha 7,5
5 Glyphosate V8-V10 8, 1 +600kg/ha refers to the leaf stage of maize as described in the BBCH scale.
These results clearly indicate that the combination of glyphosate with the plant growth stimulant, TURBOMAIZE™, result in increased crop yield.
EXAMPLE 2 GLYPHOSATE plus MAXFOLIAR™ (post-emergence herbicide)
Trials were carried out in which the applicant's plant growth stimulant MAXFOLIAR™ was mixed with a tank mix of glyphosate such that 31/ ha of MAXFOLIAR™ and the corresponding recommended volume of glyphosate tank mix were applied to soybean fields.
The control crop was sprayed with glyphosate containing no MAXFOLIAR.
Figure imgf000006_0001
The trial indicates an increase in yield of soybeans with the application of glyphosate and a plant growth stimulant, MAXFOLIAR™.
EXAMPLE 3 - PLANTSTART™ plus pre-emergence herbicides
In this example, PLANTSTART™ was used with different pre-emergence spray programs on maize, dry beans and soy beans and applied as a broadcast spray. No PLANTSTART™ was included in the spray for the control.
Figure imgf000006_0002
The results generally show an increased yield with the addition of PLANTSTART™ to a spray containing a pre-emergence herbicicde.
