Nematicide classification

Nematicides are a class of agents used to control plant nematode diseases. Most have fumigation, such as dibromochloropropane.
Fourth, herbicides This class of agents is used to control farmland towel weeds pharmaceutical.
(I) Classification of raw materials by herbicide
1. Inorganic herbicides: Herbicides that are made of inorganic substances, such as sodium chlorate, sodium potassium carbonate, etc., have generally low control effects, and most of them are fire-borne.
People and livestock are highly toxic and have gradually been eliminated.
2. Organic synthetic herbicides: artificial organic compounds that are used in herbicides. At present, most of the varieties fall into this category, and the development is very decisive. According to the Chemical Division can be divided into: phenoxy carboxylic acids (plus 2, 4 -
Drops), ethers (such as herbicide ether), phenols (processed sodium chlorophenolate), amides
(such as propanil), carbamates (such as oat bran), substituted ureas, (such as diuron), benzotriazoles (such as atrazine), organic phosphorus (such as glyphosate)
Heterocycles, (such as hundreds of dry powder) and so on.
3. Microbial herbicides; Herbicides made from microorganisms themselves or metabolites, such as Lubao No.
(b) Classification according to use of herbicides
1. Inactivated herbicides: These agents kill all plants (including crops, weeds) and make them non-renewable, also known as non-selective herbicides. Mainly used for non-farm weeding, land reclamation, etc., such as paraquat, sodium pentachlorophenol, sodium arsenite and so on.
2. Selective herbicides: Selectively kill certain types of plants after application, while not harming other plants. This selectivity is relative, not absolute, and it can only be displayed under the conditions of controlling the concentration and dosage of the cutting. Otherwise, the selectivity can be converted into virulence, and the deuterium can be added to the net and Simazine. It is harmless to corn. , but kill weeds in corn fields. It is an effective herbicide for corn fields.
(c) Classification according to the mode of action of the agent
1. Contact killing herbicide: Liu Liu directly contacted the plant tissue than death.
Can not be transmitted in the plant body, generally only kill the aboveground parts. It is suitable for controlling annual weeds germinating from seeds, such as propanil, sodium pentachlorophenol, etc.
2. Systemic water-removal agent; drug can absorb through the roots, stems, and leaves of weeds and transmit in the body, spread to the whole plant, destroying the normal physiological functions of the plant to make the weeds die. Such as 2, 4 drops, thatch and so on. However, excessive use of Yemen as a contact herbicide.

Laser Therapy Wrist Watch

Laser Therapy Wrist Watch:


The Laser Watch is an innovative 3-in-1 device that uses the latest research findings in the field of low-level-laser therapy. It combines acupuncture, local pain management and external blood irradiation and will become your ideal companion-whether at home, at work or on the go.

Areas of application: Red light

Are you also suffering from:

• Stress

• Symptoms of fatigue

• Anxiety

• Tensions

• Rapid heartbeat

• High blood pressure

• Seasonal affective disorder

• Lack of motivation

• Insomnia

These symptoms are often caused by high blood pressure and a low Melatonin and Serotonin level. The red laser is well-known for its ability to enhance cell activity and microcirculation. Furthermore, it activates the immune system by stimulating different leukocyte groups.

Activate Metabolism: Lower Blood Pressure and Improve Blood Flow

Increasing age and an unhealthy lifestyle enhance the possibility that cholesterol and other blood fats build up on vessel walls and thus impair the oxygen and nutrient supply to our organs.

Vasoconstriction leads to metabolic and microcirculation disorders which in turn result in cardiovascular and cerebrovascular diseases, high blood pressure, diabetes, stroke etc.

Laser light activates different enzymes and decomposes redundant fat in the bloodstream. It increases the oxygen amount in the blood, boosts metabolism and enhances the process of lipid peroxidation to reduce cholesterol in the vessels.

Current scientific research of Univ.-Prof. DI DDr. Gerhard Litscher and Mag. pharm. Dr.scient.med. Daniela Litscher shows the effects of the Laser Watch on the cardiovascular system. Pilot studies demonstrated that in healthy test subjects the total heart rate variability (HRV) increases briefly during stimulation with the Laser Watch. Furthermore, it caused an improvement of microcirculation (increase of 15%) during a 20-minute Laser Watch stimulation.

Relieve tensions with the laser pad

Incorrect sitting postures in front of the computer and physical or emotional tensions often cause painful muscle stiffness in the neck and in some cases even lead to tendinitis. Quite often these symptoms are also accompanied by headaches and shoulder pain which radiates into the arms. Whether sport injury or chronical pain-with the laser pad you can now easily treat aching body regions and you will achieve optimal regenerative effects on cellular level. The red light of the laser unfolds its analgesic, anti-inflammatory and reparative effects deep in the tissue layer where it induces various biochemical reactions:

• Blood vessels widen and consequently allow better oxygen transport and blood flow

• Stimulation of the mitochondrial metabolism

• Increase of ATP synthesis

• Stabilization of cell membranes
