How to Pick Insecticides for Vegetable Gardens
If you have a serious pest infestation in your vegetable garden, you will also require a serious insecticide. However, insecticides come in a wide range of forms, and not all are created equal, so you must understand the things to consider when selecting one.
Target pests
Most manufacturers create all-purpose pesticides that can kill hundreds of insects at once. On the other hand, most vegetable crops are only affected by one or two predators, and dozens of other species can benefit the plants’ development.
This is why you should first discover what kind of pests are infesting your garden. For example, if you discover Mexican beetles crowding your bean plants, you must first determine which insecticide is effective for that type of bug.
Organic vs. chemical
Many garden experts regard organic insecticides as the best solution for removing pests in vegetable gardens. This is because these solutions can successfully kill pests while causing minimal harm to the plant. Another great thing about them is that they are not toxic for humans and pets.
Get your hands on an organic insecticide whenever possible. Many of today’s most popular organic insecticides contain pyrethrum derived from chrysanthemums, and it is particularly effective in killing its target and disappears quickly from the soil.
However, this does not mean you should always avoid using chemical insecticides; you can still use them if you have persistent pests in your garden. However, remember that you must strictly adhere to the usage directions.
Application
Insecticides are available in concentrated and ready-to-spray versions. Concentrates are normally less costly but must be diluted with water first. The latter option, on the other hand, saves you time because it may be applied to the plants right away.
Longevity
Many bugs and pests are not affected by insecticide during their early stages of development because the egg protects them. This allows them to resurrect within a few weeks of insecticide application. As a result, the insecticide you select must be able to protect your plant for as long as possible.
Insecticide safety tips
In general, insecticides have two types of action: contact and systemic. Contact insecticides remain on the plant’s surface, whereas systemic insecticides penetrate deep into the plant’s vascular system. Whatever pesticide you use, there are some safety measures you should take.
1. Decide if you need to use the insecticide
In terms of severity, each pest situation is unique. Anything that cannot be dealt with in manual ways, such as cleanup with your fingertips or a hard blow from the garden hose, may demand additional strength from the insecticide.
Light infestations of plants are often easily handled without the use of an insecticide. For example, to get rid of spider mites from your cauliflower, rinse the plant in your bathtub.
In most cases, an insecticide should only be used as a last resort in cases of great urgency or massive infestation. Bugs or ants swarming all over the vegetable bed clearly show an infestation that requires urgent insecticide treatment.
2. Pick the right insecticide
As previously stated, before selecting your poison, understand what type of insects you are working against. Most insecticide labels explicitly specify what the product is intended to kill. Some treatments may only tackle several types of insects, while others address a wide range of pests.
Next, consider the formula and what you’ll feel most comfortable with. Is it ready to use, or does it need to be prepared? If you research the pests, you’re fighting, you can make your organic insecticide out of things you already have in your kitchen.
3. Don’t use too much insecticide
Remember that insecticides, even organic ones, can be harmful if used excessively. The idea here is to use only when required and just enough to eliminate insect invasion.
If you need to figure out how a product will affect a plant, test it on a single branch first. It should be noted that some insecticides may require more than one dosage. So, understand how many applications are required and wait for the recommended length of time between each.
When spraying insecticide, wear appropriate protective apparel, such as goggles and thick rubber gloves. If insecticide goes into the eyes, rinse them immediately with seawater and contact Poison Control to decide the next steps.
4. Know when to use the insecticide
Regarding pesticides, timing is crucial because many insects only respond to insecticides at specific life cycle periods. Read the labels to determine the ideal times to use the product.
Strong winds and heavy rain may also have a role. Avoid applying insecticides before a downpour to prevent chemicals from leaking into the soil. Also, avoid spraying insecticides during strong winds to avoid harming other healthy plants.
5. Safely store and dispose of the insecticide
All organic and chemical insecticides must be kept out of reach of children and pets. More importantly, adhere to label instructions for safe insecticide disposal. Contact your local government to see whether they have a program for collecting domestic hazardous material.
