Category 1: Cleverly use 5 common items to treat diseases and pests (spray 2-3 times, once every 3-5 days )

The first method: cleverly using wood ash to control pathogens and pests.

Wood ash is not only a good potassium fertilizer for agriculture, but also a good alkaline substance for disinfection and sterilization. When we were children, if we got a cut and bled, the adults in our family would often grab a handful of wood ash and apply it to the wound to disinfect, sterilize, and stop the bleeding. If we go back in time, when medical conditions were very poor, rural women would occasionally use wood ash when giving birth (of course, this is a very undesirable practice today).

In fact, wood ash has a wide range of uses in agriculture. It not only provides plants with potassium fertilizer (and other trace elements), but it's also a common agricultural tool for controlling various diseases and pests. A simple spray or sprinkle can prevent and repel diseases and pests, and kill bacteria and insects (it's effective against common diseases and pests). The method of using wood ash to control plant diseases and pests is very simple:

1. Spreading: To save time, use 30-40 kg of wood ash per acre. Spread the wood ash evenly on the ground, flower pots, and plant surfaces in the early morning or evening when the moisture is high (preferably when there is dew). The effect will be better if you can spread it on the roots of crops or seedlings and the surrounding soil, planting holes, and planting trenches.

2. Spraying: Use 10 kg of water and 1 kg of wood ash (the ratio of water to wood ash is 3:1 ) to soak the plants for 24 hours. Then filter out the wood ash residue, leaving only the water that has been soaked with wood ash. Spray the solution directly onto the stems and leaves of crops or flower seedlings.

Wood ash is amazing! If you use it regularly, it can help you control pests such as aphids, thrips, flies, and maggots that are difficult to control in melon fields, vegetable gardens, and flower pots. It can also reduce the incidence of various stubborn diseases such as wilt and rot in plants. In addition, wood ash is also very effective in improving soil structure, increasing soil fertility, and promoting growth and yield.

The second method: Cleverly using rice vinegar to prevent and control germs and pests.

Dilute the rice vinegar you often use for cooking with water and spray it on the stems and leaves of plants. Once absorbed, it not only provides plants with small amounts of various nutrients (such as amino acids, folic acid, and vitamins), improving their photosynthetic and metabolic capabilities (promoting growth and yield), but it can also inhibit or even kill bacteria that thrive in alkaline environments. It can also repel soft-bodied pests like snails , slugs , and tobacco budworms due to the unsuitable environment. If you don't have rice vinegar, white vinegar or regular vinegar will also work; using pure grain-brewed vinegar will yield better results.

When using rice vinegar to control pathogens and pests on plants, you can add approximately 25 ml of rice vinegar to 10 kg of water , dilute it to 300-400 times to make a baking soda solution, and then spray it directly onto the stems and leaves of the plants.

The third method: Cleverly using baking soda to prevent and control diseases and pests.

Baking soda, commonly found in households, is alkaline (sodium bicarbonate can also be used). Dilute it by adding 2-3 grams of baking soda to 1 pound of water to create a 0.5 % baking soda solution. Spraying this solution on plant stems and leaves can help control various plant diseases such as anthracnose, downy mildew, gray mold, powdery mildew, and sooty mold, as well as pests like ants, slugs, snails, aphids, cabbage worms, spider mites, and various small flying insects. Furthermore, baking soda decomposes into carbon dioxide and water on plant leaves, which can promote plant growth and development.

Baking soda can be used to control pests and diseases on plants because it is a strong alkaline substance that has a significant inhibitory effect on acid-loving pathogens and pests. In addition, when baking soda is sprayed on pests, it can block their stomata, causing them to dehydrate quickly, suffocate due to lack of oxygen, and die.

Fourth: Clever use of medicated oil to control pests

If you have any unwanted medicated oil at home, don't waste it. Medicated oil can be used to control common pests on plants, such as mosquitoes, spider mites, aphids, and scale insects. This is because the main ingredients in medicated oil are paraffin, menthol, methyl salicylate, camphor, eucalyptus oil, and eugenol. These substances have strong irritant, repellent, and killing properties against pests.

The method of using eucalyptus oil to control pests is relatively simple. When using eucalyptus oil to control pests, you can dilute it with water at a ratio of 1:600 ​​to make a eucalyptus oil solution, or dilute it by adding 4-5 drops of eucalyptus oil to 1 jin of water . Then pour it into a spray bottle and spray it directly on the stems and leaves of the plants.

Fifth method: Cleverly using tobacco leaf water to control pests

If there are smokers in your household, you can make tobacco water from tobacco leaves and cigarette butts to control pests: add 1 jin (500g) of tobacco leaves to 10 jin (5kg) of water and soak for 24 hours and 1 night, or boil the tobacco leaves in a pot until they turn dark brown, then remove the tobacco leaves, filter out the tobacco water, and spray it. If you don't have tobacco leaves, you can also collect some cigarette butts, soak them in tobacco water, and spray it. The method is simple: soak about 20 cigarette butts in 1-2 jin (500-1kg) of water for 24 hours and 1 night, then filter out the clear liquid and spray it.

Category 2: Cleverly use 5 substances with pungent odors to control pests ( spray once every 3-5 days , for 2-3 consecutive sprays ) .

Most agricultural pests are strongly repelled by substances with strong, pungent odors. We can take advantage of this by using common household items to repel or even kill most common pests in melon fields, vegetable gardens, and potted plants, such as aphids, flies, thrips, caterpillars, planthoppers, moths, stem borers, spider mites, ants, snails, and leaf rollers.

Because there are so many substances that can be used to repel pests, Beijing Aohe Soil Testing will introduce a few here and briefly explain how to use them. As for the reasons why they work, we will not explain them in detail. Just remember how to use them, and you don't need to know the reasons.

The first method: Cleverly using chili water to control pests.

Add 3-4 ounces of completely crushed fresh chili peppers to 10 jin (5 kg) of water and soak overnight , or boil in a pot for half an hour. Then remove the chili pepper residue, filter out the clear liquid, and spray it on the ground. Note that when using chili pepper water to control pests, the spicier the chili peppers, the better.

The second method: cleverly using pepper water to control pests.

Add half a pound of fresh Sichuan peppercorns to 5 pounds of water and boil continuously for half an hour. Then remove the peppercorns, filter out the clear liquid, and dilute it with 5-8 times the amount of water before spraying.

The third method: using ginger water to control pests.

Add 1 pound of crushed fresh ginger to 10 pounds of water and soak for 1 day and 1 night. Then remove the ginger residue, filter out the clear liquid, and use it as a spray.

Fourth: Clever use of garlic water to control pests

Add 1 pound of crushed fresh garlic to 10 pounds of water and soak for 1 day and 1 night. Then remove the garlic residue, filter out the clear liquid, and use it as a spray.

Fifth method: Clever use of onion water to control pests

Add 1 pound of crushed fresh raw onion to 10 pounds of water and soak for 1 day and 1 night. Then remove the onion residue, filter out the clear liquid, and spray it on.
