Observe your industrial plant on a regular basis and act tight if you see anyevidence of caterpillarson your broccoli ( Brassica oleraceavar.italica ) .
Common Broccoli Pests
Unfortunately , multiple garden pest regain broccoli tempt . Those that are in " worm " form or go through a caterpillar stagecoach include the cabbage looper , the simoleons worm and the diamondback moth .
Imported Cabbage Worm

The caterpillar itself is quite big , so it is easily seeable , reaching 1.25 to 1.5 column inch in length .
Diamondback Moths
Like the Brassica oleracea inchworm , diamondback rattlesnake moths ( Plutella xylostella ) are nocturnal . They lay their creamy clean eggs near the leafage veins . The caterpillars are light green and very little , only about 1/3 inch long .
Broccoli Pest Control
expert caution that eradicating all pests is generally unneeded and overkill , because it would postulate intense and frequent pesticide applications . Instead , your goal should be to control pests , knowing that some damage to a cole harvest will not necessarily affect the crop .
The scheme behind this end is calledIntegrated Pest Management , orIPM , which just means : use multiple tactics to check pests while avoiding the overuse of potentially negative chemicals . These tactics include cultural , mechanical , biologic and chemical substance strategies .
Cultural Control

Other manual types of control could include protecting broccoli and other plant with lightweight row treat that prevent adult moth from laying eggs .
Biological Control
you could make utilization of natural predators of common pests that target Brassica oleracea italica . These beneficial insects include the ubiquitous ladybug and predatory wasps .
Chemical Control
The last strategy to use is chemical control . Avoid broad - spectrum pesticide because they act on multiple mintage and belt down good insects as well as true pests . alternatively , opt for lower - risk , organic pesticides that point specific insects . These include :
