PhotonTM 500 SG
for Mitigation of Heat Stress
Introduction
Photon 500 SG, containing 500g/kg of a blend of dicarboxcylic acids, reduces the impact of environmental stressors, such
as excess light, heat, drought and other environmental conditions that negatively impact crop productivity. The active
ingredients in Photon 500 SG are natural compounds found in all plants, which control a specific enzyme system associated
with the stress response. Photon 500 SG effectively prepares the plant for the onset of environmental stress. Extensive trials
have been conducted in Australia and overseas and have proven it to be a highly effective product for mitigation of sun
damage verses current standards. Patents for this innovative product have now been granted in South Africa and the United
States and are pending in Australia.
Key features and benefits
Photon 500 SG:
• does not leave a residue so no postharvest removal is required,
• is a high quality, low dust, soluble granule formulation, applied at very low rates, which is highly cost effective,
• is compatible with conventional crop protection products such as fungicides and insecticides so no additional sprays are required,
• can be applied at any time during the growing season, from pre-plant to post-harvest, to protect foliage, flowers or fruit,
• is a systemic product which is rainfast in 4 hrs,
• has a nil WHP and re-entry period so can be used close to harvest.
Application timings
To maximize the benefit to the crop, Photon 500 SG should be applied as soon as temperatures start to exceed 30 degrees
celsius, as this is when plant productivity starts to be affected by heat stress. This could be anytime from September to April
but is generally between October and March depending on the regional area. Figure 1 below shows the maximum monthly
temperatures over the last 10 years at Swan Hill in Victoria. The yellow bars show the ideal application window for Photon 500 SG

Application
For the greatest protection against environmental stress damage, PHOTON 500 SG should be applied at the rates and specific
crop stages noted in the Directions for Use. Applications should be repeated at the intervals noted in the crop specific section.
Foliar applications should be made in sufficient water volume to provide adequate uniform coverage. A wetting agent should
be added to aid in spreading over the leaf surface. Preferred surfactants include non-ionic or organo-silicone adjuvants.
Photon 500 SG should be applied in sufficient spray volume to wet foliage. Applying to drip or beyond will be a waste of
product as Photon 500 SG is systemic.
A single application will provide minimal benefit. Maximum effective stress protection will be reached once the second
application is applied and best results are obtained from multiple applications. It must be applied to allow sufficient time for
the plant to develop a response as explained below.

Label directions and restraints:
*When applying Photon 500 SG to crops at a per 100L rate, the rate per hectare SHOULD NOT
go below 20 g/ha or exceed 40 g/ha. Photon 500 SG must be applied 4 –5 days prior to a
stress event to achieve maximum performance.
** Environmental stress mitigation program refers to the general application directions required to reduce the impact of
environmental stressors such as excess light, heat, drought and other conditions that negatively impact crop productivity.

Repeat applications at 14-­‐21 day intervals through to harvest. Early applications can be made as a band over the row. Apply prior to a cold event, ensuring adequate coverage of the foliage. Begin applications at flowering. Continue at 14-­‐21 day intervals through to harvest. Apply after watering in slips. Apply PHOTON 500 SG before the onset of a cold event and continue throughout the cold period. Apply PHOTON 500 SG at 100g/ha for the first 2 applications at 21 days apart and 50g/ha for the third and subsequent applications, at 21 day intervals. Apply to the foliage and fruit of the berry crop at 14 day intervals beginning at flowering. Use sufficient spray solution to provide complete coverage. For best results, begin applications when foliage is fully expanded. The addition of a wetting agent, such as a non-­‐ionic surfactant, is extremely important for berries that have a waxy surface, such as blueberries. Apply PHOTON 500 SG at a rate of 4g/100 L of water*. Begin applications within 7 days of petal fall. Continue to apply at 14-­‐21 day intervals until harvest. Begin applications prior to a cold event. Better results will be obtained with two to three applications applied at 14 day intervals prior to a cold event. Apply in sufficient water to provide thorough coverage.

Repeat applications at 14-­‐21 day intervals through to harvest. Early applications can be made as a band over the row. Apply after watering transplants. Apply 7-­‐14 days prior to flowering. Repeat at 14-­‐21 day intervals while flowering continues. Begin applications at flowering. Continue at 14-­‐21 day intervals through to harvest. Apply PHOTON 500 SG in sufficient spray solution to wet all foliage. For best results, begin applications one month prior to flowering. Alternatively, PHOTON 500 SG applications may begin at flowering and be repeated at 21 day intervals through to harvest. Begin applications between bloom and cap fall. Apply PHOTON 500 SG at 21 day intervals through just prior to harvest. For additional protection and better early season growth the following year, make 1 to 2 applications of Screen™ Duo beginning immediately after harvest. Photon User Guide
