Aphids are\u00a0pests\u00a0that feed on many kinds of garden plants. These tiny insects\u00a0wreak massive destruction in multiple ways. There are many different kinds (and colors) of aphids. They\u2019re small, 1\/16 inch more or less, and feed on plant sap to obtain nutrients. In greenhouses they reproduce without mating; one aphid can start a new colony. Aphids can arrive with plant material, move from one crop to another, or from nearby garden weeds to favorite host plants.<\/p>\n

Damage is caused in several ways. Large numbers can lead to reduced growth and vigor. As aphids develop, they deposit\u00a0a sticky ‘honeydew’ substance on plants on which sooty molds grow – which can spoil the appearance and marketability. Feeding by some kinds causes severe plant distortion. Aphids can transmit disease viruses to healthy plants from sickly ones.<\/p>\n

Aphids infest many greenhouse crops, garden vegetables and fruit plants, and\u00a0landscape trees, shrubs and vines. Common favorites include roses, salvia, impatiens, pansy; vegetables such as pepper, cabbage and kale, tomato; tree fruits such as apple, peach and cherry; and cane fruits such as raspberries and blackberries. A complete list would run many pages long.<\/p>\n

Their reproduction rates are incredibly fast and quickly get out of hand inside a home greenhouse where the environmental conditions are perfect. Numbers grow from a few to many thousands in a few weeks. Tiny aphids are often difficult to see and their body colors make them well-camouflaged.\u00a0Numbers increase when environmental conditions are warm and moist,\u00a0and plants are well-fertilized.<\/p>\n

Don\u2019t invite aphids into your greenhouse and garden. Inspect new plants before purchasing, particularly those bargain plants at flea markets or give-away by other gardeners. Aphid outbreaks can be managed with many effective biological agents and chemical pesticides.<\/p>\n","protected":false},"excerpt":{"rendered":"
