Solved Cancel drops from blocks

[Nikola]

Hi, I am making a farm skript for my server, and my idea is to use custom plants. I have made schematic files with WorldEdit (I have stacked 2 or more sunflower plants (only one block) on top of each other, and saved that build as schematic). I want to block item drops (sunflowers), because when one block is broken, it updates all blocks above that one block and there are sunflower drops. If you can't understand well what I am talking about, look at this picture:

Thats 2 plant block stacked on top of each other.

How can I cancel sunflower drops?

Thanks for answering, but doesn't work. No errors, it loads perfectly, but sunflower drops appear as before.

Thanks for answering, but doesn't work. No errors, it loads perfectly, but sunflower drops appear as before.

Fixed my problem with this code:

loop dropped items in radius 3 of event-location:
   delete loop-value

This may not be the perfect solution to everyone, since players may be able to drop items in that area. In my case, players can't drop items at farm region, and this works for me.
