Statistical analysis of diseases

#1
Good morning everyone,

I am currently working on a project to evaluate the efficacy of one chemical product to reduce the development of a fungal pathogen on a field.
To evaluate this I have 12 plots of 1m² each, 6 are treated every month and 6 not. Randomly disposed.
After several months of trial, I now have results every month of the fungal contamination on each plot.

The results are for example :

Plot A treated, end of july --> 5 fungal infections, that covers an area of 20 cm² and with a perimeter of 47 cm.
Plot A' non treated, enf of july --> 8 fungal infections, that covers an area of 39 cm² and with a perimeter of 68 cm.
And this for every plot, during several months.

How can I use this to prove (or not) the efficacy of the tested product ?
I was wishing to use R Studio to analyse my project.

Thanks in advance for your help

Less is more. Stay pure. Stay poor.

Can the outcome be converted into a rate? Or how do you plan to standardize it given varying plot sizes?

I am sorry but I do not really understand your question. Each treatment (so with the product and without any product) is repeated 6 times and is every time on a 1m² surface.

How is your outcome formatted? can you provide a toy example of your data frame so we can see what you are working with.

Thanks.
