## Round ID
35667

## Description of the bug
When using ammonia, trays instantly become filled with worms. The standard chemical Dinitroaniline, does not work as it used to remove worms. And research must rely on other departments for 'Pest-B-Gone.'

## What's the difference with what should have happened?
Research should be able to use Dinitroaniline to rid plant pots of worms.

## How do we reproduce this bug?
1) Plant a plant...
2) Give said plawt ammonia.
3) Worms fill tray.
4) Give plant Dinitroaniline
5) Nothing

## Attached logs

Start by reproducing the issue described for round 35667: apply ammonia to a planted tray, then apply Dinitroaniline. Trace the hydroponics and research chemistry entry points involved; done means ammonia no longer causes the reported unexpected worm state and Dinitroaniline removes worms as expected.
