The benefits of Acadian Plant Health™ (APH™) seaweed extract on citrus are well documented. As with other crops, applications during nursery, plant establishment and plant development lead to improved root growth, shoot length and improved tolerance to stresses such as drought, heat and salinity. APH™ seaweed extract helps maximize both fruit size and number, leading to increased yield, which improves gross return.
BENEFITS FOR CITRUS INCLUDE:
- Better plant establishment
- Improved resistance to abiotic stresses
- Reduced fruit drop
- Increased fruit quality
SCIENTIFICALLY PROVEN, FIELD-TESTED SOLUTIONS
IMPROVED EARLY DEVELOPMENT
CITRUS TRIAL “TANGERINA SUNKI’
SÃO PAULO, BRAZIL
In a citrus nursery trial conducted in Brazil, tangerine plants treated with APH™ seaweed extract every 15 days showed visual improvement in overall plant growth. The treated plants were visibly taller and had larger root systems. The measurements confirmed that the treated plants were 13% taller than Control plants.
IMPROVED SHOOT LENGTH
CITRUS TRIAL ‘TANGERINE’
In a trial conducted in Thailand, tangerine trees treated with APH™ seaweed extract showed increases in various areas of plant vigour 15 days after treatment. For example, the shoot length was 27.3 cm in the treated trees compared to 19.1 cm for the Control, a 43% increase.
IMPROVED STRESS TOLERANCE
CITRUS TRIAL ‘HAMLIN SWEET ORANGE’
FLORIDA, UNITED STATES
Foliar and drench applications of APH™ seaweed extract increase drought tolerance in container-grown Hamlin Sweet Orange nursery trees. This trial was conducted in Citrus Research and Extension Center of University of Florida.
Stress drought was imposed on the Sweet Hamlin orange nursery trees during week 4 of the trial, by limiting the irrigation to 50% evapotranspiration (ET). Trees treated with APH™ seaweed extract grew at a much faster rate compared to the stressed Control trees, both rooted on Carrizo and Swingle rootstocks. New-leaf growth and shoot length were increased in the treated stressed trees compared to the stressed Control trees.
IMPROVED FRUIT QUALITY
SUMMARY OF CITRUS TRIALS
In several citrus trials, the percentage of fruit that were classified as the largest size category has increased when trees were treated with APH™ seaweed extract. The average increase was 43%. Larger fruits demand a premium price leading to increase in gross return.
* The criteria for the largest size category differ depending on the type of the citrus fruit.
REDUCED FRUIT DROP
CITRUS TRIAL ‘HAMLIN ORANGE’
FLORIDA, UNITED STATES
Healthier trees hold on to their fruit. Citrus trees infected with huanglongbing (HLB) reduced pre-harvest fruit drop when treated with APH™ seaweed extract, leading to higher yield and increased gross return.
