What kind of pesticide do you use to grow strawberries?

Strawberry is a perennial herb, as early as the first century AD, strawberry appeared in poetry, but at that time strawberry is just an ordinary ornamental plant, the individual is very small, and today's strawberry is not the same thing. It was not until more than 400 years ago that strawberries began to be artificially crossed, resulting in the emergence of the strawberries we now eat. So what kind of pesticides will strawberries use in the planting process? Let's explore.

What pesticides are used in strawberries

The most commonly used pesticides for strawberries are herbicides and insecticides, such as trichlorfon, phoxim, aldicarb, etc., herbicides have 48% trifluralin EC, 80% herbicide is dichlorvos wettable powder, 50% oxanamide wettable powder, and so on.

Trichlorfon is a broad-spectrum insecticide, which has strong stomach toxicity and contact effect, and belongs to a kind of nerve poison. It has low toxicity to humans and animals, and low toxicity to ladybugs, but it is toxic to other natural enemies, parasitic wasps and predators. Control strawberry all kinds of poisonous moths, night moths and so on. Phoxim is a broad-spectrum, low-toxic and low-residue organophosphorus insecticide. it has a good effect on the older larvae of Lepidoptera pests and soil pests, and can kill eggs and leaf mites. Aldicarb (aphid fog) is a specific aphid killer, which has a special effect on aphids. Aphids can be poisoned and killed a few minutes after application.

Trifluralin is a selective pre-seedling dinitroaniline soil treatment herbicide used in orchards to control 1-year-old Gramineae weeds and perennial weeds and some broad-leaved weeds. The control effect of wettable powder on annual monocotyledonous and dicotyledonous weeds is more than 90%. It is generally diluted to 500 times of water and sprayed between rows. Clonamide wettable powder can control a variety of annual Gramineae, sedges and broad-leaved weeds, like grass is the enemy, diluted to 500 times the solution sprayed between rows.

II. Harm of strawberry pesticides

The Environmental work Organization (EWG), a US environmental agency, has released a list of "pesticide residues". The data on the list are taken from the USDA's test results of pesticide residues in 38800 common agricultural products, of which strawberries topped the "dirtiest" list for three consecutive terms with an average of 5 pesticide residues and a record high of 22. However, for the problem of pesticide spraying, simply discussing the number of pesticide residues does not have much effect, more depends on the dose to determine. However, the existence of pesticide residues in strawberries is also an indisputable fact. Because strawberries are hybrid varieties, there are a lot of pesticides that need to be sprayed during the whole growing period. As for the residues, they are actually not much different from other fruits and vegetables. Even so, people still need to wash strawberries before eating them.

The above is some knowledge about strawberry pesticides. The best way to remove pesticide residues is to use as few pesticides as possible during the growing period of strawberries.
