  1. HarvestVant ADVANCED TECHNOLOGY FOR PRE-HARVEST TREATMENT

  2. HARVESTVANT Pre-Harvest treatment for weakening the FRF (Fruit Retention Force) and improving mechanical harvesting efficiency and economics. Enhances Olive harvest process by increasing the harvested yield (dropped fruits), while shortening the harvest process and reducing the required labor HarvestVant reduces trees damage

  3. BACKGROUND Harvesting Olives has become the main expense in growing olives for Table or for Olive Oil (40 – 60% of the turnover). Some of the growers are using Ethrel. Ethrel is a plant growth regulator that releases ethylene and weaken the stalk of the fruit. However the use of Ethrel is not widespread because of its over-aggressive activity (shedding of leaves), a high user price (high volume) and the high concentration of an active hormonal substance in the finished solution. Rotem Amfert Negev/Agrovant has developed the HarvestVant - a new formulation that offers a solution to the problem. The HarvestVant increases the efficacy of mechanical harvesting while maintains a minimal damage to the shoot . The percentage of the active ingredient, ethephon in the formulation is lower compared to Ethrel

  4. HARVESTVANT APPLICATION For the Olive crop; Spray the HarvestVant 5-14 days prior to harvest, based on the FRF (Fruit Retention Force). The FRF should be 200-300 gr/fruit of Olive at harvesting, for efficient shaking results. Doses & Spray Volume : There is a positive correlation with the temperature levels The optimum temperature is 60 – 86F, the minimum temperature needed is 55F For Oil Olive :rate is 3% in the spray solution. Table-Olive and early season harvesting:4% Full foliage cover is required. Spray in volume of 150-200 gal/Acre or 1-2 gal/tree Remarks - Do not spray under rainy conditions. It may slow or even stop the physiological process - Do not spray under stress conditions, either draught or frost - Do no leave product in the sprayer for over 6 hours or overnight - Keep in Normal conditions

  7. HARVESVANT IS COST EFFECTIVE The use of HarvestVant could save cost and labor (based on 400 acres): • HarvestVant could save $75,000 and the need for 120 employees - compared to hand picking. • HarvestVant could save $20,000 and the need for 25 employees - compare to machanical picking. By dropping most of the olives we can minimize the loss of olives and save money

  9. HARVESTVANT REDUCES THE FRF In these trials the effect of HarvestVant was measured in Fruit Retention Force (FRF) = The mass (in Kilograms) needed to detach one olive fruit from its branch

  17. SUMMARY - Most of the trials were conducted in harsh climatic conditions (rain and cold). - In all the work carried out, HarvestVant has shown no Damage to the shoot and caused insignificant shedding of leaves contrary to the Ethrel compositions that caused severe shedding of the leaves. - Harvest-Vant was found to be effective in weakening the grip of the fruit and improving efficacy of mechanical shaking by mean of:a. Shortening the duration of the harvest. b. Savings in manpower.c. Reducing wastage.
