You don't mention if this is a young tree planting or a mature established tree.
Yellowing leaves can indicate a watering issue; too much or too little.

If the tree is new, water frequently enough so that the top few inches of soil are moist but not soggy. Crumbling soil is too dry, soggy soil is too wet.
If it is a mature tree make sure the soil is well draining.
Hardwood mulch can help with moisture retention if the soil is drying to quickly.
You should always inspect the tree for any infestation to rule out that issue.
If the watering issues are resolved, but leaves continue to yellow, you may want to have a soil test performed, as this could be a nutritional deficiency.

What insect are you spraying for - the honeylocust spider mite? Heavy infestations of spider mites cause early leaf drop, so it may not necessarily be the insecticide, but the insect you are spraying for.

Q. Black Locust tree

Beginning of summer in central California, the tree is about 10 years old and is now dropping its leaves.

A.

As the weather has warmed and the moisture decreases, increased water loss from the tree will cause them to drop excess leaves. This is their natural strategy to conserve energy.
If a spring is wetter then normal, this can make the issue even more noticeable.

If you provide watering and you see no other signs of disease or pests, there is no concern.

Removing suckers and watersprouts (suckers that grow from the trunk, branches or crown) is good for trees and keep them growing strongly. They should be removed right away by cutting them off close to the trunk.

Wait until late winter to prune your honeylocust tree. These trees are prone to stem cankers, or lesions, that can cause extensive limb dieback.
