We will introduce you to the world of tomato disfigurement known as catfacing – a disorder that is not contagious , but can induce important loss of proceeds .
Here ’s what I will cover :
What You’ll Learn
What Is Catfacing of Tomatoes?
How did this disorder get its name ? The reply is uncomplicated : because the disfigurement looks standardised , at least at clock time , to a small computed tomography ’s face .
A physiological upset rather thana disease , catfacing is not because of an worm or pathogen – it is because of ethnical problems in the garden .
The outcome is fruit that is distort on the prime end , or sometimes on the side .
Typically , you will see a large indentation that search like a scar . It can crack open and expose the locules – the cavities that curb the seeds .
The fruit can also become distorted and misshapen .
However , even if the peak scrape is just enlarged and the yield has not split clear , the tomato is still considered to have catface .
What Causes This Deformity?
The exact cause is strange , but many cultural condition have been connect with catfacing .
Abnormal Temperatures
coolheaded weather has been associated with the developing of this disorder . Temperatures that plunge below 60 ° farad three week before the plant blooms may step in with normal ontogenesis of the peak bud , which can manifest in catfacing .
Abnormally raging weather can also induce this condition .
Even worse is when there are wide fluctuations between temperature at Nox and during the day .
This can cause the fruit to alternate between sluggish growth and quick growth – a place that is ripe for the ontogenesis of catfacing .
Disturbance to the Flowers
Physical damage to the flowers , before or afterpollinationcan cause catfacing .
A unwashed informant of injury to the flowers is an flak by little worm called thrip . Leaf curl is a major symptom of thrip infestation .

Pruning and High Nitrogen Levels
According toexperts at UMass Extension , excessive pruning or high concentrations of nitrogen in the territory may also cause catfacing .
Dr Gerald Brust from the University of Maryland Extension suggest that the reducing of auxins – flora hormones that advertise cell elongation – as a solution of pruning may increase susceptibleness to this disorder .
Herbicide Exposure
In commercial-grade operations , tomatoes that have been exposed to the herbicide 2,4 - ergocalciferol can develop this disorderliness . The chemical mimic plant hormones , so it can disrupt the normal exploitation of the fruit .
fortuitously for the home nurseryman , comestible crop picture to chemical herbicides is unlikely .
Tomatoes That are Affected
Very with child Lycopersicon esculentum , flat - bottomed cultivars in particular , seem to be more prostrate to formulate this condition than smaller kind .
Heirloom varieties are frequently vulnerable , and you may have noticed the telltale signs of this physiologic disorder on fruit at the farmers grocery store . Fortunately , as long as terms is not serious , it does not fork over the fruit uneatable .
How to Prevent Catfacing
While you may not be able-bodied to prevent the exploitation of catface altogether , you may take steps to minimize its likeliness .

Harvesting as shortly as they are mature can downplay the hazard of cut this infection .
expert advise against eating any fruit with catfacing that has scupper tissue paper . More trivial damage to the skin can be removed before enjoying the fruit .
Fungi can produce very unsafe toxins , and you do not want to take any chances by eat fruit that could contain them .
Many Factors Cause Catface, But There Is Hope
A who ’s who of environmental broker can cause catface . These admit low or fluctuating temperatures , exuberant pruning and fertilization with atomic number 7 , flower damage from thrips , and herbicide drift .
While many of these are out of your ascendence , you may take step to minimise the fortune of this upset come about .
imbed tolerant or resistant varieties is your chief line of defense . If your crop suffered this class , try a resistant cultivar next season . Wait to plant your transplantation until soil temperatures are above 55 ° F .
Once plants are in the ground , be trusted to water on a regular basis and thoroughly , and mulch around industrial plant to continue wet .
