How important is the rate of use by label?
The misconception that "injection is more concentrated than labels and then will see a sensitive effect" is very common among farmers.
But in agricultural science,
Use of chemicals or fertilizers in excess of a certain rate (Overdose) often has more negative effects than good ones:
1. Direct impact on plants (Phytotoxicity)
• Burns and Nogs: Plants have limits on absorption. Too concentrated chemicals damage leaf tissue (Plasmolysis), causing leaves to burn, dry leaf edges or drop, especially during hot weather or dehydration.
• Growth disruption: Instead of plants using nutrients, too concentrated substances become "toxic," requiring plants to expel all their energy, resulting in growth disruption for dozens of days.
• Damaged young leaves: The plant's young leaves are very sensitive to chemicals. Injection too intensely can cause the leaves to bend, not fully developed, or dry shoots to die.
2. Drug resistance and pests are heavier than before.
• Resistance: If it is a pesticide or a fungus remover, overuse will strengthen the "surviving" and pass on the resistant genetics to the offspring, so the next time you need a stronger and stronger drug that no substance can be eliminated.
• Destroy Friends in the Garden: Excessive substances tend to kill useful insects. When all good insects die, pests can spread quickly because there are no natural enemies.
3. Effects on soil and environment
• Deteriorating soil: Leaf fertilizer or ground-falling chemicals accumulate as salt, salting the soil, hard soil, and go to hinder the uptake of other nutrients of the roots.
• The nutrient balance is lost: one of the fertilizers is too concentrated, may go "Antagonism," for example, if potassium is too concentrated, the plant may lack magnesium and calcium.
4. Economic losses
• High cost: Exceeding the rate of 1.5 to 2 times means money lost for free without the plant being used at all because the plant has a "saturation point" to receive the substance.
• Yield is not quality: In fruit trees like Durian, overuse of certain substances during infancy can cause distortion, skin damage, or poor quality texture.
Why would a label recommend that rate?
The production company has been experimented with in the lab and converted to the test that the "recommended rate" is where:
1. See the best results in performance.
2. The most cost-effective per farm.
3. Safest to plants and sprayers
Additional recommendations:
To see better results, instead of increasing concentration, "increase the quality of spraying" is recommended, such as:
• Adjust the nozzle to fine aerosol (Mist)
• Use a quality performance enhancer (leaf binding drug) to make the substance stick and permeate the leaves better.
• Select timely injection (early morning with open stomata and no strong winds)
Modern farming "Precision" is more important than "quantity." Maintaining label discipline will keep the trees in the garden healthy in the long run and save huge costs.
