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...

Five misconceptions to avoid when using plant growth regulators
Organophosphate insecticides are the most widely used and highest-volume class of insecticides in China, with many varieties and vastly differing properties, but taken together they have the following characteristics: (1) A relatively broad insecticidal spectrum. The organophosphate insecticide varieties commonly used today can control many agricultural and forestry pests, and some can be used to control public health pests...

What are the scientific methods for using bacterial biological insecticides?
From rice sowing to the seedling stage, farmers should focus on controlling seed-borne diseases (bakanae disease, rice blast at the seedling stage, white-tip nematode disease, etc.), the small brown planthopper, and the first-generation stem borers. At the rice booting stage, the focus should be on controlling pests and diseases such as the rice planthopper, rice leaf roller, stem borers, ear blast, and rice false smut. At the rice ear stage, the rice planthopper is the main target, along with...

Detailed Explanation of Key Points for Using Bacterial Biological Insecticides
Bacterial biological insecticides have advantages such as high insecticidal rate, no environmental pollution, safety to natural enemies, harmlessness to humans and livestock, and not inducing pest resistance. They are a new type of protective pesticide currently promoted for use in pollution-free cultivation. Because their control effect mainly depends on the bacterial activity in the pesticide, the following points need to be kept in mind during use...

Using specific insecticides requires particular care; mastering the method is key
Generally speaking, specific insecticides have different active ingredients, each with its own characteristics, and they also have different insecticidal mechanisms of action (that is, the principles by which pesticides kill pests). Varieties of this type often used in production today include: chlorfluazuron, buprofezin, flufenoxuron, diflubenzuron, bisultap, monosultap, imidacloprid, fipronil...

What are the precautions for using insecticides during the melon seedling stage
A agricultural supply seller from Yandu District, Yancheng City called to report that a local farmer used abamectin and dimehypo to control pests in rice fields. After application, a small amount of pesticide solution was left over and was incidentally sprayed onto 0.1 mu of soybeans grown by the family. As a result, the soybeans showed symptoms resembling scalding by boiling water the next day, then turned yellow and dried up. He asked whether the soybeans...

Six precautions to note when using bacterial biological insecticides
Biological pesticide: BT, Chinese name Bacillus thuringiensis, is a bacterial insecticide. This variety has been fully used in the main vegetable-growing areas of our country and has achieved good economic benefits. However, there are currently many BT manufacturers with varying quality, so when using it you must choose a variety of good quality. Note: BT is effective when the temperature is slightly higher...

Six key taboos to remember when using bacterial biological insecticides
Edible fungi suffer pest damage during the mycelium growth and mushroom fruiting stages due to the distinctive odor of the mycelium, so insecticides are often used when pest damage occurs. When pest damage occurs in edible fungi, the first step is to choose insecticides that are highly effective, low in toxicity, and have a short residual life, such as decis and dichlorvos; do not use banned substances such as benzene hexachloride (BHC) and DDT...

What are the precautions for using fungicides as a soil drench?
What should be noted when using fungicides as a soil drench? Please note the following points when using fungicides as a soil drench: First, in greenhouses where bacterial fertilizer has already been applied, try not to use fungicides as a soil drench for disease prevention. For land where bacterial fertilizer has been used, applying it tends to kill the beneficial bacteria in the bacterial fertilizer, causing the fertilizer to lose its effectiveness. If the crop has already developed disease, then you must...
