Biological pest control is best because it’s nature’s way

In fact, organic management is occurring throughout us with none human help. Native birds have a ravenous urge for food for insect pests, as do naturally occurring ladybug and green lacewing larvae. The grain, vegetable and fruit crops on which our weight loss plan depends could not develop with out the almost invisible presence of hordes of minute parasitic wasps that do the heavy lifting the place worldwide insect pest management is worried.

You possibly can deliver birds into your garden with birdbaths and birdhouses and by planting perennials with tubular flowers, almost all of which seem to attract hummingbirds. Useful bugs are interested in yarrows (Achillea species), sweet alyssum, penstemon, herbs (thyme, lemon balm, spearmint, English lavender, feverfew, coriander), daisy relations (zinnia, cosmos, chrysanthemum) and, particularly, alfalfa.

Still, the presence of birds and visits by useful insects via prudent plant selection will not be enough to beat insect pest points. In such instances, there are insectaries similar to Rincon-Vitova ( in Ventura that nurture and mass produce dozens of predatory insect species for control of widespread insect pests and mites. They’ll ship these useful predators right to your door.

Garden pests do not embrace solely insects, but snails and slugs, raccoons, squirrels and deer. But, if the only pests that we had to worry about belonged to the animal kingdom, garden upkeep can be rather a lot easier than it’s. A method or another, animal pests can almost all the time be managed or discouraged.

Nevertheless, in terms of pestiferous crops — weeds, that is — it appears that evidently the one approach to management sure notably pernicious varieties is through chemical software. Yet this, too, could also be altering as a result of elevated aversion to chemical use and to expanding analysis into biological weed management.

Human assisted organic control shouldn’t be new. Almost 2,000 years in the past, the Chinese language brought nests of yellow citrus ants into mandarin orchards to regulate undesirable caterpillars and beetle borers. And immediately the Chinese language use other forms of ants to discourage insect pests in rice paddies and sugarcane fields.


An Australian story of organic control of an unwanted plant is similarly illuminating. By 1925, the build-up of prickly pear cactus (Opuntia ficus-nitida) had grow to be treacherous down underneath. Tons of of sq. miles of prime grazing land had been consumed and made inaccessible by the thorny cactus. In a determined try and sluggish its spread, a lepidopterous prickly pear cactus pest from South America was shipped to Australia. Soon, its larvae started to feast on the succulent pads of the cactus. At present, just one % of the original prickly pear cactus stays.

I used to be impressed to research biological weed control upon receiving an e-mail from Sharon Reeve, who gardens organically in La Mesa close to San Diego. She has been struggling to include tropical dayflower (Commelina benghalensis) without success. Worldwide, and especially within the tropics, tropical dayflower is a highly damaging weed, having a severe influence on crop manufacturing.
