Simple method for pest control

With the advent of early summer and a marked rise in temperature, coupled with more Rain Water, all kinds of insects that endanger orchids are ready to move. When pests are rampant, orchids must be prevented and controlled in time in order to make orchids thrive. The prevention and control with pesticides is convenient and rapid, and the effect is good. As long as the medicine is three-thirds poisonous, it is better to be careful in the use to prevent drug damage. The simple method of pest control does have its unique characteristics. Many orchid friends and I have achieved certain results through practical use. Please give it a try:

Treatment of aphids: 5 grams of washing powder, 1200 grams of water, fully stirred and sprayed, once every 3 days for 3 consecutive times, the insecticidal rate can reach 100%.

Cure the snail: pour the beer into a shallow plate and put it on the ground and potted soil. The snail will smell the wine and will climb into the plate and drown.

Cure ants: after smashing the garlic cloves, dig 4 holes in the flowerpot and bury them in the pot soil. 2 the ants and earthworms in the pot soil 3 days later. The nematode will become extinct.

Cure red spider: after burning with mosquito incense containing pyrethrum, put it in an orchid basin, then seal it with plastic, smoke for 1 hour, it can kill eggs and adults.

Control scale insects: soak the ripe neem fruit in 1 jin of water for more than 1 month and take juice for use. If small scale insects are found, they can be killed once every five days and three times in a row.

The following is klg Lanyou's pest control method, which is transcribed here for reference by orchid friends:

Tobacco:

Efficacy: nicotine and nicotine in cigarettes can control aphids, red spiders, bugs, ants and other pests.

Production:

① 40g soil tobacco leaves or stems, add water 1000ml, soak for 24 hours, filter and then add the same amount of water dilution, and then add 2-3G detergent to dissolve (if the concentration of cut tobacco can be higher; adding detergent is not only conducive to adhesion, but also has insecticidal effect)

If ② does not have a weighing appliance, soak several paper cigarette butts in about 30 times the water, wait for the water to turn yellowish brown, and then add a little washing powder to dissolve it.

Use: use after filtering.

Front and back side of ① spray blade

When the ② pest is serious, soak the damaged part of the flower in tobacco water for 1-3 hours and soak the plant material at the same time, which can effectively kill the pests on the leaves and in the soil.

The remaining smoke water from ③ can be poured into the ant colony or sprinkled around the basin to kill the ants.

④ unsoaked cigarette butts buried in the soil can control small flying insects.

Note:

① contains nicotine and should not be added with vinegar, otherwise it will weaken the insecticidal power.

If ② is added with detergent, rinse with clean water the day after spraying (or immediately after soaking).

If ③ is mainly used for the control of scale insects, it is best to add detergent, or use detergent alone.

Garlic:

Efficacy: can control aphids, red spiders, shell insects, nematodes and other insect pests, but also can control powdery mildew.

Production:

Take a few cloves of purple garlic from the north, peel it, mash it, dilute it with 10 Mel 20 times of water, and filter out the residue 24 hours later.

Use:

Spraying leaves with ① juice

Pouring ② residue and residual juice into the basin can control nematodes and shell worms.

Note:

Garlic juice has a certain viscosity, in order to prevent dust accumulation, the leaves can be washed after a few days.

Leek:

Efficacy: can control aphids, red spiders and other insect pests, more effective for aphids.

Production and use:

Mash 500g leek, add water 1250ml, soak for one day and then filter, take the supernatant and spray it three times every other day.

Onion:

Efficacy: can control aphids, red spiders and other insect pests, more effective for aphids.

Production and use:

① was soaked in 1000ml water with 20 grams of onion scales, soaked for 24 hours and sprayed 2-3 times in a week.

In order to fully precipitate the active ingredients, ② can be chopped or mashed and soaked. It needs to be filtered before use.

Sharp chili (dry red wine chili):

Efficacy: it can control aphids, red spiders, whitefly, bugs and other insect pests.

Production:

① is fully dried and ground into fine powder

Add 50g ② chili noodles to 1kg water, boil for 10 minutes, then cool and filter.

③ take proper amount of dried chili peppers, add 20 times of water and boil for 20 minutes, let cool and filter.

Boil ④ with 250g dried chili seeds and 2.5kg in water for 30 minutes, let cool and filter.

Use:

① spray the leaves wet and then spray powder, coarse powder can be sprinkled on the basin surface.

② blade spray, spray pot soil.

Plant ash:

Efficacy: it can control aphids.

Production and use: 1 part of plant ash is soaked in 5 parts of water for 24 hours, filtered and sprayed.

The above methods are used for prevention, usually once a month. It's best to use it alternately.

I have not used plant ash in the above methods, mainly considering that it contains alkalinity, which is not suitable in the north. I have been using other methods for a year, and I have not found any side effects and no insect pests, but this is only my personal experience and can be used for reference.

Even so, I still want to say it first-if you copy it, in case something goes wrong, don't blame me!

In addition, beer, laundry powder, baking soda, sulfur powder and many Chinese herbal medicines also play a good role in the prevention and control of diseases and insect pests, but I don't actually use enough. We'll talk about it later.
