The new Plant Protection Act specifically allows only households that want to combine high efficacy with the least possible risk to humans and the environment. However, this requires that you only use the funds that are approved for the particular plant and only apply the prescribed amounts of this remedy. There are some pesticides that are approved in the house and allotments against aphids on tomatoes and peppers. These remedies contain various active ingredients, from neurotoxins to remedies that appear under the biological tips for controlling aphids:
  • There are drugs with deltamethrin, a neurotoxin, which is then contained in the tiny amount of 0.008 grams in one liter of the plant protection product.
  • Other crop protection products contain other toxic substances, such as pirimicarb, which works specifically against aphids (8.33 grams per liter) or thiacloprid (9 grams per liter), which can be used against a range of pests.
All these remedies are also dangerous for bees, deltamethrin may accordingly be used in the field of tomatoes and peppers from the development of the first pairs of leaves to the full ripeness of the fruit, but expressly not during flowering. Pirimicarb and thiacloprid are generally restricted to use in greenhouses or rooms, offices and balconies, where they may not be applied to flowering or bees-flowering plants.
For all three remedies there is a waiting period of 3 days between last use and harvest. All these means are not without danger for humans, which is why, in addition to the application rates, the special method of application, special prohibitions for the application in waters and all prescribed protective measures should be observed.

Alternatives to industrial aphid drugs

Then there are remedies with different concentrations of potash soap that may be used outdoors and in the greenhouse. Kali Soap is simply soft soap, in its purest form, so here you will find approved plant protection products and biological agents recommended for the treatment of aphid infestation. In the light of the approved for certain plants funds can then better assess other recommendations from the Internet:
For example, neem oil is recommended on the Internet for use on tomatoes - this is the Azadirachtin contained. Azadirachtin agents are available as home and garden pesticides, but they are not approved for aphids and for use on tomato plants. That makes sense, because in Azadi Azadirachtin is degraded much slower than z. As in apples, Neem does not kill the pests immediately, but only prevents the complete development of the offspring. Therefore, neem oil is usually far too mild for the first treatment of aphids, which multiply very quickly. In addition, against the use of this drug also speaks that aphids very quickly become resistant to neem, if the agent is not one hundred percent used properly. This happens when it rains shortly after the neem spray, the Azadirachtin watered down and does not kill the lice, but they have just taken the desensitizing dose that makes them resistant.

Mechanically and biologically combat aphids

If the aphid infestation is still very low, and you actually refuse to chemically treat the plants from which you will eat the fruits, you could try the biological-mechanical control. This means, first of all, to strip off or wash off aphids, then the plants are (repeatedly) doused with a wormwood extract or freshly prepared nettle.

In addition, you could still use ladybugs, earwigs, hoverflies, parasitic wasps or gall bladder. These natural enemies of the lice kill hundreds of aphids every day. You can simply buy the beneficial insects or collect them in the garden or attract them in the field by planting yarrow or dill next to the tomatoes. For ear-irons, you could make dwellings yourself, so-called ear-pincher bells.
By the way, did you know that your tomatoes eat the aphids themselves? Seriously: Tomatoes on the trunk have hairs that catch the aphids, the tomatoes absorb the nutrients of decaying animals. This has just been discovered and, according to research scientists, the tomatoes should be counted among carnivorous plants.
