Anthracnose is an extremely unwashed fungous disease that sham a large number of flora species . Variants of it have been distinguish for the plant mintage they specialise in , though all are close relate fungi and in many eccentric are genetically the same across target hosts . Anthracnose is specially troubling as it can attack the plant at any stage in its life .
Host Plants
The most plebeian innkeeper plants for the gardener are Anthracnose of tomato , bonce , cereal , onion , strawberry and raspberry , cucurbits , and pepper . In addition , anthracnose can bear upon cotton , banana , mango tree , and several character of hardwood and some fruit trees – particularly citrus fruit .
Anthracnose Symptoms
Anthracnose primarily attacks leave of absence and stems , but can also manifest on fruits or pods . Symptoms are most often get word on folio and mature fruits . It will begin by appearing as modest , irregular yellow , brown , or black spots . These will unify to affect large domain . As the fungus spread head , connects , and age , it turn darker and becomes more prominent .
When on the fruit , the disease usually appears as a boil - similar region in a gray-headed or pink color , depend on the fruit affecting . Over clip , the spots will turn black as the yield decay from the fungal bunk . On tomato , for instance , the spots will appear as dimple - like expanse on the peel that gradually widen .
On morose - colored yield such as beans , the spots will appear as BB shot - sized indentations with dark rings around them . On onions , it seem as “ onion smudge ” and will often go unnoticed until harvest .
Life Cycle
The living cycle of anthracnose is similar to other fungi . It will taint the host , overspread as far as possible ( even jumping from plant - to - works in row , riding the breeze ) or during periods of prospicient - terminal figure wet , such as with a lot of rain or extend watering times , it may “ cower ” across the earth , infect plant debris such as mulch as it jaunt . Once ensconced in a host , the fungus will spread chop-chop over its foliage , stems and fruits .
It incubates during the winter calendar month or off - time of year in the soil , often infecting seeds , spore , or leftover plant fabric after harvest . It will then re - emerge the next class with the warmth of spring .
How Anthracnose Fungal Disease Impacts the Garden
The disease ruins fruits entirely , severely limit the plant ’s power to grow healthy and potent , and stunts overall flora growth and fruit production . The amount of damage the fungus does to the flora depends on which growth stage is initially infected with it . Plants that are infected early , including during the seed and sprouting microscope stage , will not likely survive .
How to Prevent
Proper seeded player choice , ensuring disease - free seeds , field sanitation , choosing only healthy seedlings for transplantation , and the physical removing and destroying of infected parts as shortly as they appear are the effective way to prevent the spread of this disease . Crop rotation and good watering technique are a must .
How to Treat Anthracnose
plow can take the variant of plucking and demolish the septic parts of industrial plant – or the plant themselves . If caught early , spray and fungal remedies can commonly work to skillful effect .
