Definitions
- the present invention generally relates to plant pathogen control and more particularly to the control of pathogens in fruit crops, including apple scab.
- Environmentally acceptable fungicide compositions are used by organic growers to control apple scab and other pathogens. Examples include elemental sulphur, such as KUMULUS TM. Other fungicides comprise a yucca extract, such as those disclosed in WO/2007/139382 to Bengtsson et al.
- compositions comprising as active ingredients elemental sulphur or yucca extract, alone or in combination, do not inhibit pathogens to such a degree where virtually all the pathogens are inhibited or eliminated.
- pathogens to such a degree where virtually all the pathogens are inhibited or eliminated.
- compositions described below comprise yucca extract, elemental sulphur and salicylic acid in various quantities, applied to apple crops by spraying.
- the observed result of systematic spraying, when compared to an adjacent apple field control group which was not sprayed were remarkable. All or almost all incidents of apple scab were inhibited or eliminated from the sprayed crops whereas the adjacent untreated control crop was destroyed by apple scab.
- a second adjacent crop which had minimal spraying had significant apple scab, although much less than the control group.
- the three active ingredients were mixed in the following ranges, in an aqueous solution, per hectare (ha) of crops.
- Salicylic acid 185 g/ha - 370 g/ha
- compositions for controlling fungal foliar pathogens including apple scab, wherein the compositions comprise elemental sulphur, salicylic acid; and yucca.
- Compositions can be in aqueous form for ease of application. If aqueous compositions are used, a suitable antifoam agent is mixed with the composition to account for the foaming properties of the yucca.
- compositions comprising sulphur in the range of 2 kg - 4 kg, salicylic acid in the range of 185 g - 370 g, yucca in the range of 4 L - 8 L and water in the range of 750 L - 1 ,000 L.
- compositions of the present invention can be applied by foliar spraying. To maintain pathogen control throughout the season, a plurality of applications are done.
- compositions of the present invention and methods described herein will also inhibit fungal foliar pathogens in other apple cultivars, and in other fruit crops, including grapes, albeit with different relative amounts.
- the skilled worker having regard to this specification would optimize the amounts of each active ingredient.
- the crops evaluated with the compositions and method of the present invention include four cultivars of apple, grown in the Quebec region of Canada.
- a first time to apply the compositions of the present invention was determined to be early in the growing season, between late April and late June, to coincide with the apple scab primary season.
- a second time to apply the compositions of the present invention is during the apple scab secondary season, from late June until August in the tested region.
- the active ingredients in the compositions of the present invention are elemental sulphur, salicylic acid and yucca extract.
- the amounts of each active ingredient varied depending on the time of application and were optimized for the cultivars tested. Other amounts are contemplated, depending on the apple cultivar. In addition, active ingredients from other sources are also contemplated.
- the sulphur tested was KUMULUS DFTM obtained from BASF Canada Inc. of Toronto, Ontario, Canada which is marketed as a water dispersible granular fungicide and acaricide. The product is guaranteed by the manufacturer to be 80% pure.
- the salicylic acid tested was willow extract 25% obtained from Stryka Botanies of Hillsborough, New Jersey, USA. The product is a brown powder which is partly soluble in water. The product is guaranteed by the manufacturer to be 25% pure.
- BIOSOIL TM obtained from Agroindustrias El Alamo S.A. de C.V. of Baja California, Mexico.
- the product is a liquid which contains 97.0% botanical extract derived from the Yucca schidigera plant, 1 .0% humic acid and 2.0% citric acid. It is marketed as a natural wetting agent, soil conditioner and plant growth promoter.
- An antifoam non-active ingredient was also used during the mixing process given the foaming agent properties of yucca extract.
- Polydimethylsiloxane emulsion under the brand Antifoam OR-10TM was obtained from Momentive Performance Materials of Friendly, West Virginia, USA.
- the product is a liquid and contains 10-30% silica filled polydimethylsiloxane, 60-90% water, 1 -5% fatty acid ethoxylate, 1 -5% fatty acid ester and 1 -5% cellulosic thickener.
- compositions were mixed in a 1 ,500 L sprayer tank water prior to application on apple trees per hectare in accordance with the methods specified below. Four embodiments are provided in Table 1 below.
- compositions of the fourth and fifth embodiments comprised half the active ingredients of the compositions of the first and second embodiments, respectively.
- the fourth or fifth embodiments are applied to the crops if it is determined that there was no primary infection after proper application of the first or second embodiments, respectively. Primary infection may occur despite the application of the first or second embodiments for a number of reasons independent of the invention, including human error during application or excessive rain.
- compositions of the third and sixth embodiments comprising 0.350 and 0.330 kg salicylic acid respectively, were also mixed with 4 kg elemental sulphur and 8 L yucca, then applied to crops and yielded excellent results for the tested cultivars.
- compositions of the present invention comprised 0.300 kg salicylic acid mixed with 4 kg elemental sulphur and 8 L yucca. This composition was applied to three crop fields (8 sprays at 750 L/ha) after 4 initial sprays of a known composition with fair results. Based on this test, it was decided to only evaluate the compositions of the present invention.
- compositions of the present invention were applied to various apple crops during the apple scab infection cycle. Unlike treatments by elemental sulphur alone which are susceptible to minor rainfalls, the compositions of the present invention did not wash away with less than an inch of rainfall.
- compositions were applied by foliar spraying on the surface of the crops.
- compositions with less water were sprayed during the primary infection season for the first five applications as there were few or no leaves on the trees. Compositions with more water were then sprayed for the remaining applications as more foliage grew so that the leaves could be adequately coated during application. As the change in compositions coincided with the end of the primary infection season, the compositions sprayed during the secondary or summer season were effective.
- the apples of the second sample were treated only at the beginning of the growing season.
- a control group was used comprising thirty untreated Cortland apples in an orchard adjacent to the fields comprising the treated apples. Given their proximity, the evaluated apples were subjected to the same meteorological conditions.
- the apples were evaluated after the apple scab infection cycle (late April to late June for the area tested). From the first sample, only one of 800 apples of Spartan cultivar (0.1 %) was observed to have secondary scab. No Cortland or Mcintosh apples from the first sample had any scab. From the second sample, 28 of 100 apples (28%) had primary or secondary scab. From the control, 26 of 30 apples (87%) had primary or secondary scab.
- compositions and methods of the present invention had virtually no damage from scab in comparison with untreated apples and apples with reduced treatment.
- an organic grower uses up to six times less elemental sulphur per hectare of treated crops compared to prior art pathogen control protocols using sulphur alone.
- the compositions and methods of the present invention were determined to be as effective as non-organic alternatives, including Manzate Pro- Stick TM.
- the compositions of the present invention are suitable for application to control fungal foliar pathogens in organic crops as well as conventional, non-organic crops.
- compositions of the present invention work together to effectively control fungal foliar pathogens in crops, compared to prior art applications of sulphur alone, yucca extract alone, or mixtures of yucca extract and sulphur.
