In production, there are many small pesticide formulas, which can not only reduce labor costs and investment, but also achieve the purpose of effectively preventing and controlling pests and diseases.
1. The troublesome whitefly and whitefly: Small formula: pyridaben + dinotefuran + silicone, hit the back of the leaves and it will be difficult to prevent them from dying.
2. A small prescription for aphids that cannot be beaten away: 60% imidacloprid suspended seed coating agent for seed dressing, the validity period can be up to 90 days. This medicine can also be mixed with 2000 times of the medicine to irrigate the seedbed, and the effect of preventing and controlling aphids will be equally good.
3. Pepper flowers and fruits fall: Little secret recipe: Use 25% propiconazole 1000-2000 times, add boron fertilizer and sodium nitrophenolate spray.
4. Watermelon wilt disease: In the adult stage of watermelon, once the disease develops, use 180 grams of 50% chlorobromoisocyanuric acid + 20 ml of 40% flusilazole, mixed with 300 pounds of water to water the roots, once every 10 days, twice.
5. You may not necessarily characterize propiconazole as simply disease prevention. In fact, it has a better effect on crop conditioning.
Spray propiconazole 1000-2000 times to control chemicals and prevent diseases. The effect is quite good, but the question is whether you know how to use it. The specific usage is 1000-3000 times for green pepper, 1000-1500 times for corn, 500-1000 times for wheat, 1500-2000 times for soybeans, and 1000-1500 times for leeks. Special reminder, watermelon should not be used from the seedling stage to the fruit setting stage.
6. During the peak fruit-setting period of peppers, apply this medicine regularly. The fruits will grow the fastest and the plants will not be prone to premature aging.
920+cytokinin+nitrophenolate can increase production by 100%. If you don't believe me, give it a try.
7. Small formula to prevent watermelon fruit cracking: Spray the watermelon with procymidone twice before and after pollination. It can prevent both diseases and fruit cracking, and the effect is particularly good.
8. Root-knot nematodes are stubborn and difficult to control: The roots can be dipped or irrigated with 41.7% fluopyrid polyamide suspension, which can prevent and control root-knot nematodes, sclerotinia and powdery mildew without causing excessive drug residues.
Disadvantages of Six Commonly Used Pesticides
Fluazinam: Cannot be used at high temperatures, as it is very easy to cause harm. The control effect against downy mildew is average. It must not be compounded with EC, because the permeability is very good. After compounding with EC, the leaves will become deformed and curled. Sensitive to melons and susceptible to phytotoxicity. Try not to use leafy vegetables either.
Pyrimycin: Pyrimycin is very sensitive to temperature. When it exceeds 25 degrees, it is particularly prone to phytotoxicity. After the eggplant is treated with pesticides, small dark brown spots appear on the leaves. Chlorophytic lesions appeared on cucumbers after treatment. Severe leaf burning and whitening. Beat the bean leaves directly dry, as if they had been sprayed with herbicide. Tomatoes may develop yellowing of leaf margins.
Chlorpyrifos: Not to mention how effective this drug is in killing other insects, its quick-acting effect on spider mites is unparalleled. However, if this medicine is exposed to high temperatures and the concentration is too high, it can easily damage the leaves, causing leaf yellowing and premature aging. Therefore, when applying medicine, you must pay attention to the temperature, concentration of medicine, and spraying time. Proper use of medication will produce magical effects on red spider mites. However, this medicine has been classified as highly toxic and is no longer allowed to be used.
Copper methamine: When the drug copper methamine first emerged, everyone said it was safe, very safe. It is true that this medicine is safe enough, but it has a fatal flaw. If it is sprayed on the eggplant leaves in the morning and afternoon, the leaves will wilt on the second day, and gradually return to normal on the third day.
Glyphosate: The weakness of glyphosate is that it will not die at low temperatures. Therefore, under low temperatures, it is better not to sell this product. Farmers believe that glyphosate will kill the weeds. If it does not die, it is a fake medicine. Therefore, if you use this product to kill weeds at low temperatures, it is easy to gain a reputation for selling fake medicines. Under low temperature conditions, you can use 32.4% dripping acid and glyphosate, which has a great weeding effect at low temperatures.
Acetamiprid: Acetamiprid is a common drug used to fight aphids. Everyone is familiar with it. However, this drug has a flaw. This drug is very sensitive to temperature. At high temperatures, it has a good insecticidal effect. If the temperature is low, the effect will not be as good. It doesn't matter if it's in the shed, but if it's in the open air, you have to pay attention to the temperature of the medicine.
