Methods for Using Plant Growth Regulators on Flowers and Trees
Plant growth regulators play important roles in regulating the growth of ornamental plants, preventing excessive leggy growth, promoting rooting, cultivating strong seedlings, controlling sex differentiation, preventing flower and fruit drop, enhancing resistance, and preserving freshness during storage. However, the methods of using different plant growth regulators vary depending on the type of agent, the target plant, the purpose of use, and the plant's growth conditions...

Application Methods and Technical Key Points of Botanical Insecticides
Chemical fertilizers, pesticides and hormones are major means of agricultural production and play an important role in ensuring increased agricultural output and higher farmer incomes. With social development, in order to improve labor efficiency and increase economic returns, farmers often mix two or more of chemical fertilizers, pesticides and hormones when applying them in production. Scientific and rational...

How to avoid herbicide damage? Keep these preventive methods in mind
1. Choose the right herbicide variety; for unfamiliar varieties or ones not previously used locally, it is best to conduct a trial first. 2. Use safeners to prevent damage. For example: before sowing corn, use NA (1,8-naphthalic anhydride) antidote at 0.5%-1.0% as a seed coating, which can protect corn fields from thiocarbamate herbicide damage...

What are the methods for making plant-based insecticides?
Do not use inferior pesticides. To ensure the quality of the pesticides used, purchase them from legitimate manufacturers and pesticide sales outlets to avoid buying counterfeit or substandard pesticides, and pay attention to the production date and expiration period of the pesticides. Do not use bacterial insecticides at low temperatures; their active ingredients are protein crystals and living spores...

Diagnostic Methods and Prevention and Control Measures for Herbicide Damage
1. Soil residual herbicide damage: Farmland where long-residual herbicides such as triazines, sulfonylureas, and imidazolinones have been used cannot be planted with Schisandra chinensis within two years. If, due to a lack of understanding of the herbicide use on the planting plot in the previous two years, the herbicide damage to Schisandra chinensis is relatively severe, it cannot be remedied, because in current agricultural production there is still...

Methods for applying herbicides to wheat to prevent freeze-related herbicide injury
What herbicide is best for corn planting? Corn plants that preferably do not suffer herbicide injury are relatively sensitive to herbicides, so they should be chosen reasonably to avoid herbicide injury. For soil treatment, 40% atrazine-acetochlor aqueous suspension emulsion has high herbicidal activity, a long application period, and is safe for corn and subsequent crops. Before emergence after sowing or after emergence when weeds...
