Increasing the fruit size of pears 09/06/2015 4
Background fruit size Young fruits are provided with water and nutrients through transport channels (xylem) Fruit growth 3 weeks after full bloom
Mode of action Platina Platina increases the elasticity of the cells Due to the rapid growth of the fruits the xylem vessels tear Platina keeps them intact longer Better water uptake Better nutrient uptake More cell division
Use of Platina on pear 1 x 1,5 l/ha, ± 3 weeks after full bloom Weather conditions favorable for growth Day temperature > 15 C, preferably > 18 C High relative humidity Night temperature > 8 C Do not mix with other PGR (but Globaryll)
What to expect? Trials in Belgium on Conference 2004-2006 Year 2004 2005 2005 2006 2006 2006 2006 Experimental station Increase in fruit weight (g) PPS PPS PPS PPS PPS MVG MVG + 4 + 9 + 9 + 4 + 8 + 5 + 7 MVG = Ministry of the Flemish community PPS = pcfruit - Proeftuin Pit- en Steenfruit
What to expect? Platina = bigger pears without yield reduction 6 grams of difference in fruit weight equals about 1 mm of fruit size => 20 % within one size class up to a higher (= more expensive) size class eg. from 55-60 up to 60-65 mm Platina effect often only visible just before harvest

Combination with Globaryll 100
Platina + Globaryll 100 Platina can be combined perfectly with a fruit thinning treatment with Globaryll 100 Globaryll 100 on its own gives fruit thinning and a better fruit size Adding Platina gives a stronger thinning effect and/or an extra size effect Advice: - Tankmix - 10-12 mm, + 18 C

Recommendation No thinning Better fruit size Thinning so better fruit size Thinning + extra effect on fruit size Platina 1,5 L/ha ± 3 weeks after full bloom Globaryll 100 2 L/ha 10-12 mm + 18 C Globaryll 100 2 L/ha + Platina 1,5 L/ha 10-12 mm + 18 C
Key points - pear Platina 1 x 1,5 l/ha, ± 3 weeks after full bloom Temperature > 15 C, favorable weather Don t mix with copper Don t mix with other PGR (but Globaryll) Because Platina is taken up very rapidly, it only needs about 3 hours of dry weather after application!
