Two ladybugs moved among them.
“Those?”
“Yes.”
Dalton crouched beside another plant.
Emma knelt next to him.
“Look here.”
She gently lifted a leaf.
A caterpillar clung underneath.
Beside it were several tiny white cocoons.
Dalton frowned.
“What happened to it?”
Emma pointed.
“Parasitized.”
“By what?”
“Wasps.”
Earl leaned down.
“You mean one of those tiny things kills that caterpillar?”
Emma nodded.
“The larvae develop on it.”
Dalton looked uncomfortable.
“That's disgusting.”
Emma shrugged.
“To the bean plant, it's useful.”
Earl laughed.
Dalton ignored him.
He looked around.
“So the bad rows are attracting the insects that eat the insects.”
Emma nodded.
“Some of them.”
“And the flowers?”
“Food and habitat for beneficial insects.”
“And the pepper spray?”
“Mostly repellent. I use it where I want to reduce feeding pressure without wiping everything out.”
Dalton scratched his jaw.
“Why not just spray these six rows hard and kill everything here?”
Emma looked at the ladybugs.
“Because then I lose the predators too.”
Dalton stood.
“That still doesn't prove your system is better.”
Emma nodded.
“I know.”
He looked almost pleased again.
Then she added:
“So I planted a control block.”
His expression changed.
“You did what?”
Emma pointed across the irrigation channel.
A second bean section sat twenty yards away.
Same variety.
Same planting date.
Same irrigation schedule.
But no trap rows.
No companion flowers.
No targeted garlic-pepper treatments.
No sticky-card management beyond basic observation.
They walked over.
The plants did not look destroyed.
That mattered.
Emma didn't want a fake comparison.
They looked like normal beans under moderate pest pressure.
But damage was spread everywhere.
Not concentrated.
Almost every row had leaves with holes.
Several plants showed clusters of aphids.
One had significant beetle feeding.
Earl walked through slowly.
“This looks worse than the inside of your other block.”
Emma nodded.
Dalton examined three random plants.
Then five.
Then ten.
“How much worse?”
Emma opened a second notebook.
“Last count, forty-three percent more leaf damage.”
Dalton looked up.
“Forty-three?”
“In sampled leaves.”
“And pods?”
“Twenty-eight percent more in the production rows on the managed block.”
Earl whistled.
Dalton stared at the page.
“You counted pods too?”
“On marked sample plants.”
“How many?”
“Thirty plants per block.”
“Why thirty?”
Emma hesitated.
“Because fifty took too long.”
Earl laughed.
Even Dalton smiled.
For the first time that morning, it wasn't directed at her.
He handed back the notebook.
But he still wasn't finished.
“You know one season doesn't prove this works every year.”
Emma nodded.
“I know.”
“Different weather, different pest pressure, different timing.”
“I know.”
“You may get hammered next season.”
“I know.”
Dalton frowned.
“You say that a lot.”
Emma closed the notebook.
“Because being right once doesn't make me right forever.”
Earl looked at Dalton.
“That sounded aimed at somebody.”
Dalton glared at him.
Emma walked back toward the main plot.
By then Daniel had joined them.
He carried two empty crates.
“What'd I miss?”
Earl pointed at Dalton.
“He discovered your daughter can count.”
Daniel looked at Emma.
“She charge him for the lesson?”
“Not yet.”
