The idea is to immobilize the whiteflies carrying the virus and prevent them from spread to other industrial plant . Then , dispose of the plant – bag and all – but don’tcompost itor exit it in the garden .

Septoria Leaf Spot
Septoria leaf spot is cause by the fungus Septoria lycopersici . In tomatoes , the symptom of the Septoria leaf spotusually start as pocket-size , orbitual spots on the plant ’s lower leave-taking . The spot become more large as the disease progresses . The center of the spot may also turn blanched , with black fruiting body seeable in the center – finally , the affected plant leave yellow and die .
To lower the likeliness of this disease , ensure enough air circulation between them by supporting themwith a stakeor inraised bedsto quash humidity and prevent fungous growth . Because this fungus go around its spores through pee , use mulchto prevent water from splashing from the grease onto the lower leaves . splay crop every year to disrupt the lifecycle of the fungus .
If the symptoms of Septoria leaf spot start to appear , isolate the involve works and rationalise the damaged parts . Doing so increase the air flow around the plant , reduces humidness , and slow down the disease . In plus , using fungicides in the early stages of the disease can help insure it . Burn or dispose of infected plants or debris .
However , it is best to use fungicides as a forethought throughout the growing time of year ( apply after every seven to 10 Clarence Day ) . take those with copper , chlorothalonil , or mancozeb as fighting ingredients . The copper ions in these antimycotic interpose with the enzyme systems of the cell of pathogen and prevent them from growing or replicating .
Late Blight
Late blight is a fungous disease that impact Lycopersicon esculentum plant and other works in the nightshade family line . recent blight symptom include pee - soaked spots on the plant ’s folio , stem , and fruit . The spots may jump small and become bigger and darker over meter , with livid mold appearing on the bottom of the leaves in humid conditions . Infected yield may also have dark or olive - colored sunken orbit .
Better air circulation is the first step to prevent tardy blight from affecting your tomato plants . infinite plants about 3 feet apart and drip mould irrigation towater tomatoesfrom the bottom to denigrate the amount of piddle that comes into liaison with the works . This reduce the humidness around the plants and prevents the fungus from taking grasp .
Weekly applications of protectant fungicides with chlorothalonil or fixed copper can forbid late blight . They kill the fungal spore on the works ’s aerofoil , preventing them from germinate and infecting the plant tissue paper . If your plants get later blight disease , isolate them and spray fungicides weekly to prevent it from spreading .
If a plant is gravely affected , lay to rest or burn it rather than compost it . Composting septic tomato plants can spread the disease , as the fungus may retain to spread and produce spore in the warm and damp surround of the compost pile .
Early Blight

Early blight is a disease cause by the fungus Alternaria solani . symptom commonly begin with little , dark touch on the plant life ’s older leaves , which then spread out and cause the leaves to turn yellow and break . The position may also have a fair game - like appearance with a drear out ring and a lighter nerve centre . As the disease work up , it can affect other plant life parts , including the stem and fruit .
Early blight expand in humid , stagnant conditions , so improve air circulation around your tomato plants by pruning lower leave within 10 inches of the ground and reduce out crowded plant . To prevent this disease , stave off wetting the plants ' leaf .
Weekly applications of antimycotic with chlorothalonil , maneb , or Cu can serve control and foreclose this disease . As shortly as you see the symptom of other blight , isolate the affected plant and remove any infected leaves , stems , or fruit . Sanitize yourpruning shearsbetween each cut to avoid go around the disease . Use one part blanching agent and nine component H2O to disinfect the shears .
Verticillium Wilt
Verticillium wilt is due to the filth - borne fungi Verticillium albo - atrum and Verticillium dahliae . ab initio , the disease causes v - shaped lesions that extend inwards from the folio border . Yellowing of leaves and stunted growth can also go on . In the late stages , the plant starts to droop . The plant seems to be recovering in the dawn . However , come good afternoon , when the pathogens are active , the plantbegins to wilt . This procedure continue for day until the whole flora die .
No specific fungicide exists for this disease , so you’re able to not eradicate verticillium wilt disease once it affects a flora . Remove the unnatural plants immediately to prevent the spread of the disease . The best room to avoid verticillium wilt is to implant resistant Lycopersicon esculentum sort . These include ' Beefy Boy VF1F2 T , ' ' Crista VF1F2F3N , ' and ' Jet Star VF1 . '
The disease - carry fungus kingdom can live in the soil for years , so practice crop rotation to prevent verticillium wilt .
Anthracnose

Anthracnose is a disease that affects ripe and overripe tomatoes . It ’s due to Colletotrichum phomoides fungi . The symptoms include small , vacuous , circular spots that grow and become drear as the infection continues . The fungus can also regard the unripe fruit , but the symptoms only come out once it is ripe .
The fungus circularize when body of water splash from one plant to another due to rainfall or overhead irrigation . So , avoidingoverhead wateringis the best path to foreclose this disease .

In improver , revolve your cropsafter every two years . Always implant the tomatoes in a well - draining grunge enrich with compost to aid disease resistance .
