Some Common June Pest Problems and Solutions

Are you beginning to see signs of unwanted pests in your plants? June seems to be the time of year when insects and diseases make their first grand appearance in the garden. Here is a list of some of the problems you might be encountering now and the solutions we recommend to keep your hard work green and blooming!


Many dusts or sprays are highly toxic to honeybees. If application of these materials to plants is necessary during the bloom period, do not apply during hours when bees are visiting the flowers.


Solutions for fungal diseases:

Good cultivation practices are important. Fungal spores need a wet surface to germinate so keep plant matter as dry as possible. Do not use overhead watering, or if you do, water early in the day so the foliage is dry by nighttime. Prune plants to allow more air circulation and facilitate the drying of foliage. Some chemical products you can use are Copper Fungicides (copper fungicide soap is best for veggie blight), Triple Action, and Sulphur Dust…


Fire Blight:
A highly destructive bacterial disease. Pear, quince, apple, crabapple, and pyracantha are extremely susceptible. There is no cure for fire blight but sometimes you can successfully prune a tree before the disease kills it.

Blossom-end Rot:
Blossom-end rot is caused by calcium deficiency in the plant. While this may be a result of low calcium levels in the soil, it is often the result of irregular watering. Symptoms occur at the blossom end of the developing fruit. Initially, a small watery rotted spot appears, which grows and darkens quickly as the fruit develops. The rot can eventually cover up to half of the entire fruit surface and will turn black and leathery. The disease doesn’t spread from fruit to fruit because it is environmental in nature so fungicides and insecticides are useless.
Blossom-end rot can be controlled through regular watering practices and maintaining the supply of calcium to the developing fruits. Hi-Yield is a product we recommend for blossom-end rot problems.
