Definitions

  • the present invention relates to a process to improve the yield of strawberry crops.
  • CN 104130059(A) describes a plant-growth regulating agent Huaguoling capable of promoting yield increase of melon and fruit.
  • CN 104718849(A) describes a process for improving the yield of tsaoko amomum fruit by spraying a sucrose solution, such that pollinating insects are attracted.
  • CN 104273131 (A) describes the use of tetrahydropyrimidine and hydroxy tetrahydropyrimidine to promote production of melons and other fruits.
  • Strawberries are a widely-grown fruit belonging to the genus Fragaria. It is grown on most continents and is appreciated for its distinctive fragrance, bright red color, and sweetness. It can be consumed fresh, as jam, ice creams, milkshakes, and in many other products. The yield of strawberry varies widely, depending on the cultivar, season of growth, and latitude, and numbers of 12,000 to 25,000 Ibs./acre are reported.
  • CN 104829395 discloses using a fertilizer based on decomposed chicken dung, plant ash, canal mud older than 3 years, rape seed cake, urea, Gentiana scabra Bge, mint, capsicum, Chinese honey locust, and a water-retaining agent, which can increase strawberry yield.
  • CN 103833476 discloses a fertilizer comprising microbial flora, a humic acid, a nitrogen fertilizer, a phosphatic fertilizer, a potash fertilizer, a boric acid, an insecticide, and water-soluble parting agent which increases the yield of strawberries.
  • Anthracnose is a strawberry disease affecting all parts of the plant including fruit, crowns, leaves, petioles, and runners. Three related species, Colletotrichum acutatum, Colletotrichum gloeosporioides, and Colletotrichum fragariae are associated with anthracnose worldwide. All strawberry cultivars can be affected but some such as cv. Albion, cv. Camarosa, cv. Chandler, and cv. Portola are especially susceptible to anthracnose. The disease can increase during wet years or with over-irrigation.
  • the disease can reach epidemic proportions during the establishment of commercial grower fields for fruit production when foliar sprinklers are used in addition to drip tape irrigation under plastic mulch.
  • the pathogen can survive in infected plants and plant tissues in soil for at least nine months in the absence of host plants.
  • several weeds are known to host the pathogen including chickweed, fiddleneck, and vetch.
  • strawberries pre-plant nursery stocks are planted in infested soil, they become infected when they come in contact with soil containing fungal spores. Conidia are not airborne but are splashed onto crowns, stems, or fruit by rain or irrigation water.
  • infected nursery stock In fields that have been fumigated, the disease usually originates on infected nursery stock or from volunteer strawberry plants in adjacent fields. In addition, inoculum can come from contaminated soil on field equipment. The disease will develop quickly following periods of warm, rainy weather. Under unfavorable conditions, early infections may become quiescent and be activated once conditions are conducive (i.e. , warm, humid weather, rain, or sprinkler irrigation). Crown rots can develop in young plants soon after planting or when warm temperatures occur. When crowns are infected, the entire plant may wilt and die.
  • Water or fungicide treatments can be used on transplants before planting in production fields. Running water treatments can wash off most of the soil and may remove inoculum from transplants.
  • azoxystrobin and a combination of cyprodinil and fludioxonil are presently amongst the treatments of choice.
  • These compounds however have major drawbacks. In the first place they are non-natural, i.e. from a synthetic origin, potentially phytotoxic, and secondly it has been observed that pathogen populations that are resistant to these fungicides unfortunately are present (i.e. in US states of California and Florida).
  • synthetic agrochemicals to control plant pathogens has increased costs to farmers and has caused harmful effects on the ecosystem. Consumers and government regulators alike are becoming increasingly concerned with the environmental hazards associated with the production and use of synthetic agrochemicals for protecting nursery stocks and seeds from pathogens.
  • agrochemicals are fraught with problems such as bonding of the agrochemicals to the soil and the need for expensive and complex chemical application equipment and worker's safety.
  • plants can be adversely affected by agrochemicals, as these chemicals can be toxic to seeds and plants that sprout from the seeds. Such toxicity limits the amount of these agrochemicals that can safely be applied.
  • the invention relates to a process for increasing the yield of strawberry crops, the process comprising the step of applying of a polyene antifungal agent to the roots of a crop-bearing strawberry plant prior to planting said plant and/or to the medium to which the plant is to be planted.
  • the polyene antifungal agent (or polyene fungicide) is preferably part of a composition, preferably a liquid composition, such as an aqueous composition which preferably comprises at least one additional compound selected from the group consisting of surfactants, sticking agents, carriers, adjuvants, solvents, dispersants, emulsifiers, wetting agents, stabilizers, antifoaming agents, buffering agents, and antioxidants.
  • Such liquid composition may comprise between 1-10,000 ppm of the polyene antifungal agent.
  • the polyene antifungal agent may be applied to the roots by dipping the roots in a liquid composition comprising said polyene antifungal agent.
  • the polyene antifungal agent is preferably natamycin, preferably comprising needle shaped crystals having an average length of between 0.1 and 20 ⁇ .
  • the natamycin may comprise at least 90% w/w needle shaped crystals having an average length of between 0.1 and 20 ⁇ .
  • the invention further provides a crop- bearing strawberry plant of which the roots have been treated with a polyene antifungal agent.
  • the invention also provides the use of natamycin to prevent or reduce anthracnose in a strawberry plant.
  • Natamycin is registered as a postharvest fungicide of fruit crops (e.g. citrus, stone fruit, pome fruit) in the United States.
  • the compound is classified by the EPA as a bio-fungicide. This classification includes biological organisms, pesticidal compounds that organisms or plants produce from genetic material added to them, or naturally occurring substances that are non-toxic or less toxic than conventional pesticides.
  • Natamycin is a biofungicide because it is a natural fermentation product of the bacterium Streptomyces natalensis and other species of Streptomyces. It is part of the reduced risk pesticide classification of the Food Quality Protection Act of 1995.
  • pesticides are generally safer than other conventional pesticides and help broaden IPM practices and reduce exposure risks to humans, show less toxicity to non-target organisms, and have less environmental impact.
  • Compounds classified as bio-pesticides by the US-EPA are exempt from tolerance in the US, Canada, and Mexico.
  • Natamycin is a broad-spectrum biofungicide that is effective against many fungi within the Ascomycota (e.g. Botrytis and Colletotrichum spp.) and Zygomycota (e.g. Rhizopus stolonifer) genera that are pathogens of strawberry and has a minimum inhibitory concentration of ⁇ 10 ppm for most of these organisms.
  • natamycin has been used in the food industry as a preservative of dairy products (e.g. cheese) and dried meats for over 30 years. During this time, no resistance in target organisms including Penicillium spp. has ever been reported. This has rendered natamycin as low risk for resistance development. Natamycin can, amongst others, exist as stable needle-shaped crystals having an average length of 0.1-20 ⁇ , which have the advantage over conventional natamycin suspensions of avoiding problems caused by settling as disclosed in WO 2006/045831.
  • WO 2014/085565 discloses a method for controlling fungal pathogens, notably pathogens that cause sudden death syndrome like Fusarium spp., by application of a composition comprising a polyene fungicide to the soil in which a plant or seed is to be planted or to plant roots.
  • the polyene fungicide may be applied by soil drenching or direct application to plant roots via immersion/root dipping.
  • WO 2014/191449 and WO 2014/191450 disclose methods for enhancing plant growth and crop yield by application of a natamycin producing bacterial strain to seed, or to the medium in which the seed is to be planted (WO 2014/191449), or to a plant (WO 2014/191450), but again not in relation to anthracnose.
  • WO 2015/034359 discloses an antifungal soil treatment composition for preventing crop losses comprising an antimicrobial compound, especially the polyene fungicide natamycin, and a polyelectrolyte complex. The polyelectrolyte complex dramatically increases the antifungal activity of the natamycin.
  • the present invention discloses results on strawberry cultivars, such as for example cv.
  • natamycin appeared to be a highly effective pre-plant dip, similar in efficacy to azoxystrobin and a combination of cyprodinil and fludioxonil. Natamycin decreases the incidence and severity of disease, decreases plant mortality, and increases yield as compared to the controls of inoculated and non-inoculated plants, as well as that of several other fungicides evaluated. Additionally, natamycin is very effective when plants are inoculated with azoxystrobin-resistant isolates of the pathogen.

  • Baby strawberry plants of cv. Portola were either inoculated or non-inoculated (naturally infected). Inoculation was done by dipping plants for 4 minutes in conidial suspensions of Colletotrichum acutatum, and then drip-dried. Plants were then stored for 8 h at 20°C, or 3 days at 5°C. Plants were then treated with natamycin by dipping them for 10 seconds in a liquid which was obtained either by adding 13.3 oz of a 10% w/v natamycin suspension to 150 gallon of water or which was obtained by adding 26.6 oz of a 10% w/v natamycin suspension to 150 gallon of water. The plants were then planted in different rows for each treatment, one feet apart and the yield was evaluated for fruit yield after 6 weeks. See below Table 1 for results.
  • Azoxystrobin a commercially available synthetic strobilurin fungicide was applied at 8 fl.
  • Switch ® a synthetic fungicide comprising cyprodinil and fludioxonil available from Syngenta, was applied at 8 oz./150 gal.
  • Plants were allowed to drip-dry and were stored overnight at 5°C. Plants were planted one foot apart in double-row beds in a randomized complete block design with each bed representing a single block (replication) and a total of four blocks. There were 10 plants each of cv. Portola and cv. Fronteras in each replication in the inoculated plant portion of the field, and there were 20 plants per replication for the non-inoculated cv. Portola plants. Overhead irrigation was applied daily for 30 min for the first week, and then twice a week for the remaining time (one month total), similar to commercial practices.
  • Plants were evaluated periodically for disease and phytotoxicity over the course of the trial. As plants develop disease symptoms, fungal isolations were done from diseased tissue to validate the symptoms as anthracnose. For this, pieces of crown and leaf tissues from the margins between diseased and healthy tissue were surface-sterilized with sodium hypochlorite and rinsed with sterile, distilled water. A small sample of this plant tissue was removed, cut into pieces, and plated onto 10-cm potato dextrose agar media plates amended with ampicillin and rifampicin to inhibit bacterial growth. Plates were incubated for 5-6 days at 25°C, and fungal colonies were identified using morphological characteristics.
  • Product effectiveness in managing root necrosis caused by Colletotrichum acutatum was evaluated by inoculating bare-root transplants of Fragaria X ananassa cv. Florida Radiance with a mixture of four Colletotrichum acutatum isolates, two sensitive and two resistant to Quinone-outside inhibitor (Qol) fungicides. Plants were inoculated by spraying a suspension of 106 conidia/ml onto plant roots using 300 ml per 100 plants. After inoculation, plants were kept at room temperature overnight and were transplanted into plastic-mulched raised beds. Beds were 28 in. wide on 4-ft. centers and contained two staggered rows of plants spaced 12 in apart within and 15 in. between rows.
