Madagascar pepper plants are commonly infect by disease whether from fungus , bacteria , or transmitted by insects . Preventing disease is always more effective than strain to decimate it . A well - balance soil ecosystem will keep pathogen from multiplying and infecting plant . A level-headed plant life is less vulnerable to disease . Appropriate watering and auspices from abrasive conditions will go a long way .
Fungal Diseases
Some common fungal diseases known to afflict pepper industrial plant are :
Powdery mildew ( PM ) shows up just as it sound , as a mildew - corresponding bloodless powder on thesurface of the leave-taking . This disease is common in moist clime and toward the end of the season . Prevent PM by pruning for maximal airflow and avoid overhead watering . withdraw any affected foliage and mulch .
Southern blight affects peppers in warm regions . This fungus lives in the soil and make the stalk of untested plants to rot , toss off the entire plant life . luck of constitutive compost applied as a top dressing will help reduce the presence of blight . Crop rotation is another method of control .
Damping off hap when peppers are seedlings . It affect the freshly growing stems of seedling causing them to rot and the plant to fall over . This fungus hold up only in very blind drunk habitat . forfend overwatering seedling or keeping them in too gamey of humidity .
Bacterial Diseases
Bacterial Leaf Spot ( BLS ) is due to a bacterium unremarkably on theseed of the plantbut once enclose it also survives in the grime . Symptoms include black and chocolate-brown detection that hap on thefoliageeventually leading to folio drop . Prune or displume affected works . Purchase disease - liberal germ or disease resistive miscellanea and recitation craw rotation .
sonant Rot is another bacterial contagion that shows up only on clean fruits . Once harvested , affect fruits exhibit sunken lesions and bacterial ooze . This disease is associated with warm , humid weather patterns and flying yield - use up dirt ball . Reduce humidity if possible and control insect population .
Other Diseases
Parasitic dirt - dwelling nematode worm can infect peppers much like a disease . This trouble is often called ‘ pepper disease . ’ Symptoms include wilt , stunted plants with stubby roots and watery root system . Encourage beneficial predatory nematode population by applying charged compost tea . There are new resistant pepper varieties .
Viruses can also affect peppers . The Mosaic virus is the most commonly seen . This causes leaf curling , scrawny growth , and mottled fruit . virus can be transferred just by touching plant so sanitation in the field is crucial . Remove affected plants and do not plant peppers in that position for two years . coating of compost or compost tea leaf will assist .
