Current situation of our breeds
Adorelle
Adorelle has a plant type that can handle a lot of light and a poor climate very well: the more light the better. No leaves were taken from the head in only a few weeks in the previous 8 weeks. So far, Adorelle growers have seen the best results with those who use a more generative rootstock.
Work in a less generative weather type with a good peak temperature in the afternoon and a sufficiently low pre-night (12-13°C, if possible) to stimulate bunch strength and set. The 24-hour temperature may be around 21°C with a light sum of 2000J/cm2.
We now see that fruit production often only slightly exceeds 100 fruits per m2 per week. Continue to aim for sufficient production; pruning will not be necessary, Adorelle is a variety that does not overload itself. We therefore advise you to take another head leaf with you, especially if the crop needs some extra generative guidance after the longest day.
Sweetelle
At Sweetelle we generally see highly generative crops. In the top 4-5 bunches we now see more single bunches in response to the high plant load. Around mid-May I stopped taking leaves from the head. This can be started again from about the end of July, if the crop allows this.
The average fruit weight varies from 11 to 12.5 grams, depending on how the fruit is pointed. Production is 95-120 fruits per week, partly depending on the pruning policy. The plant load has remained high for longer than in previous years, reaching more than 700 plants (sometimes close to 800) per m².
Manage plant loads.
Do not allow the plant load to increase too much in late summer (not above 600-650/m²), this will be at the expense of the vitality of the crop, especially after the longest day. We recommend that you prune at least from the end of July to keep the plant load in line with the available assimilates. We see growers who consistently remove secondary flowering from the 3-4th truss below the flowering truss generally generatively stronger crops without this costing production! The average fruit weight remains better at the end of the season, with a higher harvest standard because fewer bunches are harvested.
Duelle:
Plant load and fruit weight:
Duelle is generally nicely balanced and has handled the available light well; we see sufficient growth and strong bunches. The percentage of split bunches did not fall below 40-50% even at maximum plant load. The plant load is still between 650 and 700 plants per m², higher than in previous years around this time.
Pruning and plant balance:
Pruning can keep the plant balance in order in the summer. You can now start setting the 3 branches to 2. For weaker plants, the bunch can be singled out to keep the crop uniform.
Just like with Sweetelle, you can start taking a leaf from the head again around the end of July if the crop starts to fill out more.
Watering and fertilization:
When the weather is forecast to be warm, keep a close eye on evaporation and continue to aim for sufficient calcium available for the plant until at least mid-September. We recommend making significant adjustments to the Ca/K ratio in the fertilization schedule when a period of high evaporation is predicted. As soon as the period with a lot of evaporation is over, you can switch back to a normal schedule.
TIAM23-5003:
Is a ToBRFV resistant newcomer that is being tested by many companies, with good results. The crop and fruit type is very similar to Duelle, the production potential has also been proven to be in line with Duelle. The quality and taste of the Prodelle* (TIAM23-5003) are undoubtedly good. In addition, the Prodelle* (TIAM23-5003) is resistant to mildew and cladosporium, just like Duelle.
The Prodelle* (TIAM23-5003) will be commercially available from approximately early September.

Baldomero (TIAM22-0102), Tatoo (TIPM22-6757) and Bamano
Baldomero is our new ToBRFV resistant orange snack tomato and it performs very well in the first commercial cultivations. The crop and fruit type are similar to Bamano.
Tatoo is also a new, commercially available, ToBRFV resistant orange snack tomato. In addition to its ToBRFV resistance, Tatoo is also resistant to TYLCV, among others.
At both Baldomero and Bamano, even at high plant loads, we still see many split bunches (up to >90%) with an easy setting, which means that the plant load can easily remain high. We therefore also recommend pruning the 3rd and 4th branches to control the plant load and maintain balance in the crop.
Until about the beginning of August, Baldomero and Bamano do not need to take a leaf out of their heads.
Climundo
Climundo has a stable plant type with a lot of endurance and very smooth flower development; Even now we see around 7 to 9 flowers per bunch. The crop filling is average and the truss strength and set are definitely good.
For the coming period (until approximately August 10), we recommend continuing to prune at 6 fruits per cluster for crops with an assimilate surplus. We see in current commercial crops that Climundo can handle this very well; it will optimize plant balance, quality and production.
We got to know Climundo as a variety with a higher potassium requirement. Therefore, keep a close eye on the potassium figure and adjust in time. In addition, Climundo is very strong against blossom end rot; an adjustment (increase) in the potassium dose is therefore not an immediate danger to susceptibility to blossom end rot.
Macrolophus seems to develop (very) easily on Climundo. Make sure that the macrolophus population does not become too high (above approx. 7-10 per plant).
