Why do my pepper leaves have brown spots?
[1] Bacterial Leaf Spot on Pepper Leaves
Bacterial leaf spot is most potential to pick if your black pepper leaves acquire irregular browned stain .
Bacterial disease because of the bacteriumXanthomonas campestris pv . vesicatoria , which usually travels on transplants and come , is a severe job .
For this reason , it overwinters in quick , moist environs with short ventilation .
A bacterial disease can kill your pepper prematurely in some case , especially if it is n’t catch early and process promptly .
Bacterial leaf billet symptom can be found on about every part of the plant that is above earth . Stem canker , fruit spots , and brown , temporary leafage spots are examples of these .
Water - soaked lesions on lower and older leaves are other warning signs . They start out unripened or yellow but speedily turn a dark browned color .
tender , humid weather accelerates the development and darkening of these lesions . They can grow to a diam of up to a quarter - inch .
The ripe position are light-headed browned or burn in the middle , with bumpy , darker edges .
The brownish spots may dry out out and fall off if the humidity is too lowly . Leaves that have been hit by this have a shattered or hollow stage appearance to them .
Foliage that has been exposed to the trouble may turn yellow , then brown , and eventually fail .
Even infect fruits are not immune to the disease . They may also get raised , corky , or scabby lesions . yield that have been divulge to the fungus will eventually pit or rot .
A bacterial folio spot is intimately impossible to assure once it ’s a full - blow infection . To add revilement to accidental injury , there ’s no feasible curative for it .
Prevention , good sanitisation , and early controller are , therefore , your best tools :
It would help if you also treat pepper seeds before planting :
Spraying with an constitutional antifungal early in spring can help . I usually spray my peppers every ten to 14 days using copper - containing fungicide ( see to it the late cost on Amazonhere ) .
This will only help to slow down the contagion rate , though .
[2] Spots on Pepper Leaves Due to Sunscald

The scalded leaves will ferment ivory white or brown over prison term . They ’ll also scrunch up up and feel ironical or brittle to the touch .
The affected fruits may burst and crack up at the scalding points . The scalded sphere will become soft and mushy and will get down to rot .
Unfortunately , sunburned leave and fruits can serve as entry points for diseases and pests . If the problem is not resolved , the unnatural leave will fall off prematurely .
other detection is crucial to keep sunscald in check
determine out for leaf - eating bug , like caterpillars , slugs , and snail , as their feeding action expose the leaves and fruit to sunscalding .
Install row soma or binding to protect your theme from sunscald
[3] Phytophthora Blight of Pepper is Causing Brown Spots
The fungal pathogenPhytophthora capsicicauses Phytophthora blight on pepper plants . It is also the grounds of fruit hogwash , stem rot , jacket guff , and rootage waste in the majority of pepper cultivar .

The primary grounds of flower last buncombe in peppers is a severe calcium deficiency and in the main occurs in peppercorn yield .
Calcium is require for the shaping of cell rampart . If the capsicum fruits or leave grow too quick and the plant life can not supply enough calcium , they will rot and develop dark-brown lesion or patch .
This is vulgar when the soil has been consume of atomic number 20 . The same is true if the grease is too acidulent or contains high sodium , ammonia , and aluminum degree .
break your white pepper too much piddle after a teetotal spell can also prevent calcium absorption from the soil .
flower end rot is exacerbated by overwatering and drought consideration . So , keep the land moist at all times . Mulch can be used to keep grime evenly moist .
Correct acidic soil by liming it to a pH of 6.5 - 7.0 .

Common signs and symptoms of Ca deficiency in peppers include :
atomic number 20 deficiency in pepper is have or exasperate by :
gibe the soil to see it is n’t too acidic or too scurvy in Ca .
If the soil is too acidic , lime , sulfur , aluminum sulphate , or crushed limestone must be applied to raise the pH to around 6.5 - 7.0 .

[6] Anthracnose

The Anthracnose fungus thrives in warm , damp environments with little air travel circulation . Fungal spores enter your industrial plant via irrigation or rain spatter .
Low light source and overwatering experimental condition can exasperate the situation .
symptom can be set up on intimately every part of the above - ground pepper . However , the leaves and fruit give birth the brunt of the damage .
