Products used to prevent premature aging of crops are mainly divided into four categories: the first category is regulators, the second category is trace elements, the third category is biostimulants, and the fourth category is fungicides that partially inhibit crop respiration.
1. Regulator
Regulators include amine esters, increased amine production, etc. amine esters can increase the content of chlorophyll, protein, and nucleic acids, increase the activity of peroxidase and nitrate reductase, regulate the water balance in the body, and delay plant aging.
Increasing amine production mainly plays an anti-premature aging role by inhibiting the decomposition of chlorophyll in old leaves. Generally, in the middle and late stages of crop growth, repeated use can achieve the purpose of anti-premature aging.
2. Trace elements
Trace elements play a role in resisting premature aging by increasing the disease resistance of crops and extending the life of leaves, especially manganese, which can prevent some spot diseases of crops. Copper can prevent bacterial diseases of crops, zinc can promote the synthesis of indole acetic acid, and magnesium is a component of chlorophyll. Iron can promote the synthesis of chlorophyll, molybdenum can promote the synthesis of amino acids, boron can promote the transportation of sugar, and calcium can increase the thickness of the cell wall.
3. Biostimulant dosage forms
Biostimulant formulations include amino acids, fish protein, and seaweed bacteria. They can all play a role in rooting, nourishing roots, and extending the life cycle of the root system. Such a function can increase the absorption activity of nutrients.
4. Fungicide
Fungicides include pyraclostrobin, prothioconazole, fluopicolin, etc. These mainly inhibit the respiration of crops and reduce the consumption of organic nutrients to prevent premature aging of crops.
