propargite

This pesticide is available in the market under the brand name Umayt. This compound belongs to the group of sulfur-containing poisons and sulfite esters family, which has strong and long-lasting contact properties. This acaricide with a wide range of acaricides is used on fruit trees, agricultural plants, ornamental nets, proparagite is also effective on ticks resistant to phosphorus poisons and should be recommended once during the cropping season. The half-life of this compound in the soil??? it is day This mite killer is in the vicinity of strong alkaline substances and strong acidic substances??? decomposes in water to the amount?? It has solubility in milligrams per liter. Mechanism of action Propargite is a mite killer with long-lasting contact properties. This mite killer has a non-systemic effect that partially penetrates the outer layer of the leaf, but remains mostly on the surface of the leaf. Therefore, in products sprayed with Propargite, especially fruit trees, the residual amount in the flesh of the fruit is very small. This acaricide is also effective on ticks resistant to phosphorus poisons, but due to the prevention of resistance, it should be recommended once during the cropping season, and it is necessary to alternate the use of acaricides with different mechanisms of action. Indications Control the propargity of many species of plant pest mites (especially in the mobile stages) in many such as grapes, seed and stone fruit trees, citrus fruits, nut trees, vegetables, tomatoes, cotton, corn, legumes, ornamental plants. he does. The best time to use this acaricide is the first spray: before spring (from the beginning of bud swelling to before bud opening) and Second spraying: by observing??? The number of moving stages of the mite on a leaf. Propargite should be used with caution on pears, roses, strawberries, cotton, legumes. It is also better to spray early in the morning. In the case of acaricides, the frequency of use with other acaricides should not be forgotten. The interval between the last spraying with this acaricide and the harvest?? It's the week. Compatibility and mixing This mite killer is effective on crops such as pears, roses, strawberries, and cotton with a height of less than? cm causes plant burning. Also, symptoms of plant burn are observed on citrus fruits and volubia. This acaricide cannot be mixed with alkaline compounds, oils for winter and summer spraying, as well as poisons that contain a large amount of oily solvents.

Systemic Insecticide

Dimethoate is an insecticide from the group of organophosphates. - Dimethoate maintains its systemic effect for up to 14 days with a rapid shock effect, and its use for most pests is when the first pest is observed. - Do not use this insecticide on kernels because it causes plant burn and leaf fall. - The minimum interval between the last time of spraying and harvesting is 14-21 days depending on the conditions. - The use of this insecticide when the plant is growing rapidly will result in the best results. - One in a thousand foliar spraying is effective for all sucking pests and melon flies. Pest product dosage Cereals: common green aphid poisonous aphid 1 liter per hectare Sugar beet: sugar beet aphid Zanjerak Sabz (Curly Top carrier) 1 liter per hectare Cotton: green chain of cotton 1 liter per hectare Fruit trees: Sardsiri Shepshak 1 liter per thousand liters of water Soy: aphids, thrips and other sucking insects 1 liter per hectare Alfalfa: stem nematode

Fenpropatrine

Fenpropathrin pesticide is available in the market under the brand name Danitol 10% EC. Fenpropatrine is a pyrethroid insecticide with non-systemic action and contact and digestive effect, which is used in the form of 10% EC emulsion to control insects and plant pests. Fenpropatrine also shows the effect of repelling insects. Making this compound is a revolution in the production and supply of chemical insecticides. Fenpropatrine is very stable against sunlight (of course, it decomposes under direct ultraviolet radiation), but when it is exposed to light for a long time, it oxidizes and its effectiveness decreases. Because it has little evaporative properties. Its durability on the product is fairly long, 10 days. The half-life of DT 50 fenpropatrine is 2-7 weeks in river water and 6 weeks in distilled water, its active period is 1-5 days in soil and 4-6 days in plants. Gastrointestinal toxicity of this compound for humans and warm-blooded animals is moderate, but its skin toxicity is low. Mechanism of action Fan ProPatrine has a quick knock down effect. This effect is not directly related to the lethal effect of the poison, because the amount of poison required to cause the death of ticks is usually much higher than the amount needed to paralyze them. The effect of this combination is the same as that of Pebartrine. The effect of fenpropatrine is caused by inhibition of nerves and has a direct relationship with temperature. Fenpropatrin reduces the sensitivity of the postsynaptic area to nerve stimulation and increases the release of gamma aminobutyric acid GABA in the presynaptic area, thereby preventing the transmission of nerve messages. Fenpropatrine is lipophilic and is easily absorbed by the cuticle layer of insects and the surface of the leaf, that is why it is resistant to being washed away by rain. The insecticidal properties of fenpropatrine depend on the recommended dose for each pest and the complete coverage of the poison layer on the leaf surface. In addition to the shock effect, this compound also has the property of repelling (in large quantities) and not feeding pests (in small quantities). Also, by preventing the feeding of adult ticks and reducing their vital actions, it reduces eggs. Indications Fenpropatrin is used to control the movement of all types of mites, except Europhides mites and insects such as whiteflies, minnows, leaf-eating and stem-eating insects, aphids, psyllids on seeded fruit trees, citrus fruits, grapes, ornamental vegetables, cotton, greenhouse plants. It is a usable weight. Compatibility and mixing So far, there has been no report on the incompatibility of fenpropatrine on male plants in the recommended dose, but this poison cannot be mixed with alkaline compounds (such as Berdovo compound...).

captan

Kaptan 50% powder with wettability Captain 50% WP Protective and curative fungicide Protective and Curative Fungicide Captan is a protective fungicide from the phthalimide group, which is used as a powder that can be mixed with water to control a wide range of fungi. Captan does not evaporate under normal conditions and is insoluble in water. It remains stable in powder form at temperatures below 60 degrees Celsius for a long time, but its solution decomposes quickly in alkaline environments. Due to the fact that this compound decomposes quickly in alkaline environments and high temperature, therefore, it should not be mixed with lime and calcareous compounds (such as Bordo compound) and you should not use calcareous water when using it. Product name, type of pest, dosage Apple: black spot 3 per thousand Peach: peach leaf complexity (camel lip) 3.5-3 per thousand Fruit trees: sieve disease 3 per thousand Grapes: false white 3 per thousand Chickpeas: plant 2 per thousand Forest trees: seedling death for soil disinfection 7.5 to 10 grams per square meter and stirring the soil to a depth of 10 cm

Terribenrone methyl poison

Tribenurone methyl inhibits cell division by inhibiting the biosynthesis of the essential amino acids valine and isoleucine. - Herbicide belongs to sulfonylurea group. Absorption through aerial organs with little or no activity in the soil. - The maximum frequency of spraying is 1 time per year for each product. - It is not recommended to use it as a mixture with other sulfonylurea group herbicides or consecutively with herbicides containing sulfonylurea compounds, unless it is mentioned on the label. - It is better to spray when the weeds are small or grow fast. - This herbicide is effective on the leaves and roots of cereal weeds. - Spraying large weeds, which are often less sensitive, should be done completely. - Weed control in dry conditions may not result in good results. - Weed death may take 1-20 days. Higher doses of this herbicide are recommended for semi-sensitive weeds such as Shahtare and Haftband. The effect of Granstar on wild artichoke, cheese, wheat flower, sizab and desert screw is weak or insignificant. Hence the addition of moyan or tufordi may be required. - It is not recommended to use it on products that are prone to stress or do not have active growth.

Emulsifying oil

Oils play an important role in controlling some pests such as aphids, aphids, and mites. Especially for fruit trees, non-fruit trees and ornamental shrubs. Also, new formulations of oils are used today to control greenhouse pests, vegetables and plant diseases such as powdery mildew. The oils used in agriculture are called by different names, but perhaps the best name for them is horticultural oils. ) is. Volk 92 brand emulsifiable oil is one of the widely used pesticides in the field of agriculture, and this company was the first and for many years the only producer of the above product, and it is very popular among farmers. One of the advantages of Volk 92 oils is that it is less dangerous for humans and insects, especially insects that are natural enemies of plant pests, this point indicates that oils play an important role in biological control and integrated management of pests, its toxicity is at a minimum. As much as possible, they disappear quickly due to evaporation and leave a little residue. The insecticidal property of Volk 92 creates a thin, impenetrable oily layer on the bodies of insects and their eggs by closing the respiratory pores, which causes the eggs, larvae and immature insects and mites to suffocate and in this way causes the destruction of soft adult insects. So, for optimal results, spraying should completely cover the body surface of insects.
