Can you get imidacloprid if cucumber is greasy?

OK. Imidacloprid is used to kill aphids in cucumbers and has a good effect. But be careful with the dosage.

How many days can I eat imidacloprid cucumber spray? This is a question that many people are concerned about. Imidacloprid is an insecticide that is used in the control of cucumbers. So, how long does it take for imidacloprid to be sprayed on cucumbers before it is safe to eat?

First of all, it is important to know the residual time of imidacloprid. It is reported that the residual period of imidacloprid on cucumber is about 7 days. This means that there may be residues of imidacloprid on cucumbers for 7 days after spraying. Therefore, it may not be safe enough to consume cucumbers during these 7 days.

Secondly, it needs to be judged according to the amount of medicine sprayed. If the dosage is small, it is recommended to wait for more than 10 days after spraying before consuming. This will better ensure the safety of cucumbers.

Finally, the Jiansheng Hall decided to choose organic cucumbers. Organic cucumbers do not use insecticidal herbs, so they are relatively safer. Of course, organic cucumbers will also be relatively high.

In general, imidacloprid should wait for more than 7-10 days after spraying cucumber before eating. If you are more concerned about the safety of cucumbers, it is recommended to choose organic cucumbers.

<> imidacloprid can hit cucumber seedlings, and can mainly control aphids, whiteflies and other pests at the seedling stage. Imidacloprid is a nicotinoid ultra-efficient insecticide, which has the characteristics of broad-spectrum, high efficiency, low toxicity, low residue and safety for humans, animals, plants and natural enemies, and has multiple effects such as contact killing, stomach toxicity and systemic absorption, etc., and is mostly used for foliar spraying, and can also be used for seed dressing, mainly used to prevent and control stinging and sucking mouthparts pests.

1. Can imidacloprid hit cucumber seedlings?

1. Cucumber seedlings can be used to control aphids, whiteflies and other pests with imidacloprid. When planting cucumbers, 500-1000g of 4% imidacloprid granules can be used, mixed with 30-50kg of organic fertilizer for hole application, mixed with the surrounding soil to transplant seedlings, and then covered with soil, which can effectively prevent the harm of a variety of pests.

2. Imidacloprid is a nicotinoid ultra-efficient insecticide, which has a broad spectrum, high efficiency, low toxicity, low residue, pests are not easy to produce resistance, and is safe for humans, animals, plants and natural enemies, and has multiple effects such as contact killing, stomach toxicity and internal absorption, mainly used for the prevention and control of stinging and sucking mouthparts and shouting filial piety finch pests, mostly used for foliar spray, and can also be used for seed dressing. The product has good rapidity, has a high prevention effect 1 day after the drug, and the residual period is about 25 days.

2. What are the main pests and diseases at the cucumber seedling stage?

1. There are two main types of diseases at the cucumber seedling stage, one is frost damage, root burning, rooting, prudence and other non-infectious diseases, and the other is the disease caused by fungi, bacteria, viruses, nematodes, etc., such as cataplexy, downy mildew, gray mold, bacterial horn spot, anthracnose, blight, blight, etc. In addition to taking corresponding agricultural measures for prevention and control, some conventional and broad-spectrum protective agents such as chlorothalonil and thiophanate-methyl can also be sprayed after planting for prevention.

2. The main insect pests at the seedling stage of cucumber are aphids, whiteflies, whiteflies, whiteflies, thrips, mites, red spiders, etc. Once insect pests occur, they should be treated with drugs as soon as possible, and the insecticides with better control effect are imidacloprid, acetamiprid, avermectin, acemetropolitan, pymetrozine, aclice, etc.

Can be used. Can be ** aphids, red spiders, thrips and other pests.

Usage: 10% imidacloprid, 40% chlorpyrifos and other prevention and control.

Note: Cucumbers should not be sprayed with any pesticides after they are picked.

Imidacloprid is a nicotinoid ultra-efficient insecticide, which has the characteristics of broad-spectrum, high efficiency, low toxicity and low residue, pests are not easy to produce resistance, and are safe for humans, animals, plants and natural enemies, and have multiple effects such as contact killing, stomach toxicity and systemic absorption. When the pest comes into contact with the agent, the normal conduction of the central nervous system is blocked, causing it to paralyze and die. The product has good fast-acting effect, has a high prevention effect 1 day after the drug, and the residual period is only skin for about 25 days.

The efficacy is positively correlated with temperature, and the high temperature has a good insecticidal effect. It is mainly used to control stinging and sucking mouthparts pests.

Imidacloprid control hall poor meadowsweet aphid, apple tumor aphid, peach aphid, pear psyllid, leaf roll moth, whitefly, spotted loon fly and other pests, can be sprayed with 10% imidacloprid 4000 6000 times liquid spray, or sprayed with 5% imidacloprid emulsifiable concentrate 2000 3000 times liquid spray. Cockroach control: You can choose Shennong's cockroach bait.

Continuous use in recent years, resulting in a high level of resistance, has been banned in the country on rice.

Precautions. 1. This product should not be mixed with alkaline pesticides or substances.

2. Do not pollute beekeeping, sericulture sites and related water sources during use.

3. Appropriate medication, two weeks before harvest, prohibiting medication.

4. If you do not eat it with caution, immediately induce vomiting and send it to the hospital in time**.

5. Keep away from food for storage to avoid danger.

Hello dear. Yes, the amount. Cucumbers are sprayed with 300x vinegar 3 times during flowering and fruiting to thicken the stems and increase the leaf area.

After the cucumber climbs all over the shelf, break off the excessive and dense branches, let it be transparent and ventilated, concentrate nutrition, put 500 grams of vinegar on 15 20 kg of water, spray it before 9 am on the second day at 3 p.m., and spray it once every half month. In this way, the cucumber not only bears more and more large, but also the melon strips are straight, and the biggest advantage is that it is free from aphid disease and downy mildew. Table vinegar contains more acetic acid and trace amounts of lactic acid, amino acids, carbohydrates, sugars, gums, proteins, and glycerol, aldehyde compounds and various salts.

Some of the substances sprayed on vegetables can be directly absorbed and utilized by plants, which can accelerate chlorophyll synthesis and improve photosynthetic efficiency. Promote the metabolism of substances and energy in the body of vegetables. Improving the ability of vegetables to absorb water and fertilizer and their ability to resist stress, so that vegetables grow vigorously and vigorously, which is conducive to the accumulation of dry matter, thus producing obvious yield increase.

Imidacloprid and parachlor aphids are only effective against aphids and can be used

The manager of the cucumber picking period is very important, and we all know that the summer cucumber picking period is in the high temperature, high humidity, and high incidence stage of pests and diseases, so the key to achieving high yield is to adopt scientific management methods.

Scientific management of fertilizer and water.

Entering the full melon period, the summer cucumber grows vigorously, should be watered and topdressed in time, and at the same time, spraying strong melon can make the melon thicker, improve the nutrient delivery capacity of the strong stem, strong seedlings, promote the rapid development of the melon body, beautiful melon shape, juicy and delicious.

Strengthen pest and disease control.

It is necessary to achieve early prevention and early treatment, and add a new high-lipid film with a new high-lipid film in time after the onset of the disease, so as to increase the efficacy, make the fruit surface bright, and improve the quality of cucumbers.

Harvest in time. It is advisable to harvest early and frequently, generally harvested every other day, and can be harvested every day during the full melon period.
