Can you use Yates Mavrik on Citrus trees to kill caterpillars?

Unfortunately Yates Mavrik isn't registered for use on citrus we would advise you to use Yates Success Ultra , a bacteria derived product, for caterpillar control. Please note - a one day witholding period applies to the fruit.
If you would like more information on growing citrus:
Step 1. Prepare
Dig in some compost or well-aged manure. Choose a sunny spot with well drained soil. Plant dwarf citrus in a large pot.
TIP: Many citrus are grafted onto a dwarfing rootstock such as Flying Dragon. Check the label.
Step 2. Feed
Citrus are very hungry plants. Feed at least twice a year, in early spring and late summer. Feed with Yates Dynamic Lifter Organic Plant Food.
TIP: For an added nutrient boost, feed with Yates Yates Thrive Natural every two weeks during the growing season.
Step 3. Harvest
Taste-test citrus fruit to check and see if they're ready to eat. Eureka lemons will continue to produce ripe fruit throughout the year.
TIP: Thinning excess fruit when they're small will encourage larger fruit to develop.
Step 4. Protect
Well-fed citrus aren't often troubled by pests and diseases. Keep a good layer of organic mulch over the root area but don't let it contact the trunk.
