Farmers who use organic practices to control pests can buy products that are made from natural sources to spray or dust the infected plants with. They can also use a method of planting called companion planting. Using this method, plants that benefit each other are planted together. In the case of aphids, Nasturtiums and Garlic help control them and can be planted throughout the garden for that purpose. They purchase ladybird beetles, also known as ladybugs, by the thousands and release them near the affected crops, so the ladybugs eat the aphids. Also, other bugs can be released that do no harm to the crops, eat the aphids and have waste, which is good for plant fertilization.
[1] Proper cultural practices help. That means proper care for proper soil structure. Appropriate drainage, fertility and moisture levels in soil make for proper nutrient intake by plant roots and for less severe plant stresses. Stressed plants attract bully aphids. [2] Treat with environmentally-friendly products such as horticultural and neem oils, and insecticidal soaps whether store-bought or homemade with dishwasher soap and water. [3] Don't kill beneficial insects such as lacewings, ladybugs, parasitic wasps, and praying mantids. They eat bad bugs such as aphids.
[1] Home gardeners tend to start at the lowest level of potency. So they tend to use horticultural oils and insecticidal soaps. [2] Farmers tend to start at higher levels of potency. They want quick results. They don't want the several applications that may be needed when using less powerful, but more environmentally friendly controls. So they use malathion. [3] Malathion's the most commonly used organophosphate insecticide in the U.S. It's not that toxic, unless absorbed or ingested. Once inside, it becomes malaoxon, which is a problem.
The introduction of beneficial insects and natural enemies is a way in which gardeners can eliminate aphids without engaging in direct kills or using insecticides. The insects in question (Coccinellidae family) will eat the aphids as well as such other garden pests as mealybugs and scale.
There are several organic pesticides you can make at home that are effective in controlling aphids on your tomato plants. One formula is two teaspoons of dish-washing liquid in a small garden spray bottle (32 oz.) filled with water. Spray tomato plants, especially under the leaves. This remedy can be used alone or alternated with another formula of three parts of lukewarm water to one part vegetable oil and a few drops of dish-washing liquid. Spray plants once a week, preferably in the earlier part of the day, alternately between solution
Another alternative is a garlic based spray that many seem to say works. See formula below-
Encourage or introduce natural enemies is one way to kill aphids without using insecticides.
Specifically, aphids are part of the world's food web of predators and their prey. Aphids function as predators when they feed on a plant's phloem and xylem sap. They in turn serve as food to such beneficial insects as ladybug beetles, a voracious aphid-eating predator and therefore natural enemy.
Encouragement to or introduction of natural enemies accounts for one way to kill aphids without applying insecticides. Aphids function as predators when they feed upon a plant's phloem and xylem sap.

to eat aphids (aphids eat plants garderners use ladybirds to get rid of aphids all the time)
They help the world by killing aphids that can kill crops so that farmers don't have to use poison
Use an insecticide spray for aphids, or try spraying them with a solution of dish soap and water.
Nothing, they help farmers by eating the aphids that eat their crops.
Lady Birds eat aphids, which in turn eat plants. For this reason, Organic farmers use them as a form of pest control, as the aphids eat their crops and the Lady Birds keep the population under control.
yes... Aphids are small bugs that eat and destroy plants and farmer's crops, but ladybird's eat aphids, so they are useful to farmers and gardners.
no you cant use diazinon to kill aphids let me tell you why you cant cause diazinion is smaller then aphids
With an insecticide. Sevin is among the safest.
The introduction of natural enemies and the use of organic controls are ways to get rid of aphids without harming milkweed plants. Ladybugs tend to be the most beloved, diligent, intrepid beneficial insects to introduce and support when dealing with aphids. Horticultural oils against eggs and insecticidal soaps against immature and mature stages will not harm milkweeds or milkweed-lovers such as monarch butterflies.
To get rid of ants on cymbidiums, you can use ant products on the market specifically for use on those types of plants such as a diluted solution of an acephate or carbaryl based insecticide. When there are ants found on cymbidiums, it is a possibility that there is an infestation by mealybugs, aphids or scale.

Attention to cultivation requirements, introduction of natural enemies, removal by gloved hand or mechanical tool, row covers, and use of horticultural oils and insecticidal soaps are environmentally friendly ways to get rid of aphids. Heavy aphid presences indicate such environmental stress as prolonged drought or human error as over-fertilizing, over-watering, or under-watering. Plants whose heat, light, moisture and nutrient needs are respected tend to have fewer problems with such swarming insect pests as aphids and mealybugs.
