Safe use of pesticides in flowers

1. Comply with the rules for safe use of pesticides

In flower cultivation, the prohibited pesticides are: methamidophos and methyl parasulfide Phosphorus, parathion, monocrotophos, ammonium phosphate, BHC, DDT, toxaphene, dibromochloropropane, dipyrimidine, dibromoethane, herbicide, aldrin, dieldrin, mercury preparations , arsenic, lead, diclofenac, fluoroacetamide, glycofluoride, tetrafluorochloride, sodium fluoroacetate, tetrafluoroacetate, etc.

2. Take safety protection measures

Pesticide applicators must take prescribed safety protection measures to prevent poisoning. The remaining liquid medicine and cleaning fluid for pesticide application equipment should be concentrated and safely disposed of, and should not be spilled randomly. Empty containers are not allowed to be reused. Empty containers should be collected and disposed of properly and labeled for safe storage or centralized disposal.

Abandoned and expired pesticides must be disposed of in accordance with relevant national regulations and cannot be discarded casually to avoid causing phytotoxicity to flowers or poisoning humans and animals.

3. Scientific cultivation reduces the use of pesticides

Through farming measures, some diseases and pests can be eliminated and conditions unfavorable to the occurrence of diseases and pests can be formed. At the same time, the ability of flowers to resist diseases and insect pests should be improved, such as cleaning the fields, treating diseased remains, reducing the sources of pests and diseases, planting reasonably densely, increasing ventilation and light transmission in greenhouses or greenhouses, removing water damage in a timely manner, reducing field humidity, and using scientific formulas. Fertilize, etc., to make flowers grow robustly and improve their resistance to diseases and insect pests.

4. Strengthen physical control

In order to avoid the development of insecticide resistance, physical control should be used as much as possible. For example, hanging yellow sticky boards can be used to trap aphids and leaf miners, and silver-gray films can be hung in the field to repel aphids while increasing light intensity. Taking advantage of the phototaxis characteristics of many nocturnal insects, we can use light trapping, bait trapping and other methods to eliminate pests. Insect-proof nets can also be used to reduce the chance of pests occurring.

5. Carry out biological control

Biological control is also a measure to reduce the use of pesticides and avoid the development of drug resistance in flowers.

First, use bacteria, fungi, viruses or their metabolites that can cause disease or death of pests to prevent and control pests. Usually, the harmful microorganisms of pests are cultivated artificially, and then made into powder and sprayed to kill the pests. For example, Bacillus thuringiensis in bacterial preparations is extremely toxic to lepidopteran insect larvae and has excellent killing effect. Test results show that the use of fungi to kill insects is also very effective. If Beauveria bassiana is used to parasitize Lepidoptera, Coleoptera and other insects and snails, it can kill pests very effectively. The poplar louse Erythrium fungus has extremely high pathogenicity to whiteflies. The research and application of using viruses to control pests have also made great progress, with nuclear polyhedrosis viruses being used more frequently. Insect viruses are highly specialized, highly pathogenic, and have long-lasting effects. In practical applications, virus preparations are often made into aqueous agents, platinum agents, wettable powders, etc., and are sprayed or applied into the soil to prevent and control insect pests.

The second is to use the antagonism between microorganisms and the metabolites of certain microorganisms to inhibit the growth and development of flower-pathogenic microorganisms, and even kill them. These substances are antibiotics. For example, flower fungus fertilizer code-named 5406 can prevent and control certain fungal diseases, bacterial diseases and mosaic virus diseases of flowers.

The third is to use the biological chain, food chain relationship or parasitic relationship in nature to prevent and control pests. For example, daylight bees are used to control cotton aphids; dragonflies, praying mantises, etc. are used to hunt pests, etc.

Plant immunity and the active ingredients in plant sap can also be used to prevent and control pests and diseases. For example, garlic juice solution can prevent and treat many types of germs. The use of plant physiologically active substances to prevent and control plant diseases and insect pests is currently the focus of research at home and abroad, and is one of the promising methods. In addition, the use of bioengineering methods to control pests and diseases is also a new development trend, such as genetically modified technology.

6. Prescribe the right medicine to the case

To prevent and control flower pests and diseases, we must first understand the causes of pests and diseases, the infection cycle and their ecological environment, and master the time, location and scope of the damage. Prescribe the right medicine.

1. Medication for non-infectious diseases (1) The middle part of the upper leaves of the plant will be like fire and appear light red, but there will be no mold in the affected area after rain. (2) Water damage can lead to root rot and easy lodging. The leaf edges of seedlings damaged by frost are first dry, scorched and wrinkled. There is no mold in the affected parts after rain, and the stem bark is cracked. (3) Drought causes wrinkles and drooping of the middle and upper leaves. (4) Pollution makes the leaves dirty and easy to clean. Fertilization causes wilting of young shoots and stagnant growth. (5) Nutrient deficiency causes plant growth to be retarded, leaves deformed and dull, and leaves falling off from bottom to top along the stem. Flower care knowledge

Which flowers are not suitable for spraying water on the leaves?

For example, flowers with downy leaves often cause leaf rot because water droplets falling on them are difficult to evaporate. Such flowers include: African violet (Purple Bamboo Plum), toad-leaf begonia, gloxinia, etc.

The pseudobulb in the center of the Clivia leaf cluster is also afraid of water intrusion, especially during the pregnancy bud period. Water intrusion will affect the extraction of arrows.

The tubers, leaf buds, and flower buds of cyclamen will rot when exposed to water.

For plants that have already bloomed, avoid spraying large amounts of water on the leaves, which will cause the petals to become moldy, affect fertilization, and reduce the flowering and setting rate.

2. How to disinfect soil?

For chemical disinfection, commonly used 84 disinfectant can be used. The concentration should not be too high, usually two to three percent. Use a sprayer to disinfect evenly. Spray and stir the soil at the same time.

3. What kind of water should be used to water flowers?

Water can be divided into soft water and hard water according to the amount of salt it contains. Since hard water contains a variety of salts, long-term use for watering flowers will cause brown spots on the leaves of the flowers, affecting their ornamental value. Therefore, it is ideal to use soft water. In addition to soft water, you can also choose water sources with mild water properties, such as lake water, river water, pond water, etc.

Now with the improvement of living standards, it is more convenient for us to use tap water. Since tap water itself contains a large amount of chlorine and the water temperature is relatively low, it is not suitable for direct use to water flowers and needs to be placed 1 - Available for 2 days. Or use a container with a relatively large opening and leave it indoors for a day and night before use.

The water used for fish farming also contains certain nutrients, and it is also beneficial to water flowers.

In addition, there is also a method of watering flowers with Liangbaikai, which is also very effective. You can try it.

Finally, a reminder, do not use water containing soap or washing powder when watering flowers, let alone oily stains. This is extremely harmful! Miscellaneous Talk on Flowers and Feng Shui
