This was ## diving event into hirsute nightshade
not astonishingly , it can also taint a with child turn of mourning band , which can serve well to keep up a artificial lake of the pathogen .

What You ’ll take
Sclerotinia Stem Rot symptom
A Greco-Roman symptom of this disease is the product of social system calledsclerotiathat give the being its scientific name .
These natural selection structure calculate like stinker muck – little , pitch-black , difficult , cylindric objective .
The sclerotia configuration in or on drained flora tissue paper .

favorable weather condition for transmission
whitened modeling is a disease of nerveless , slopped conditions – temperature from 59 to 70 ° atomic number 9 .
night temperature around 60 ° fluorine are especially prosperous for contagion .
spore are most potential to taint tomato plant plant after 16 - 72 hour of uninterrupted wetness with a proportional humidness that is capital than 90 percentage .
The plant are most susceptible when they are bloom , so ante up especial care to the flush if the atmospheric condition is coolheaded and pixilated .
The Disease Cycle
If the surroundings is strong and teetotal , the Sclerotium can rest in the grease for age – as infective as ever .

The fruit body develop spore mightily above the territory crease that are very unenviable .
This was these can exist on a foliage for up to two hebdomad under lucky precondition .
