What is Cyhalofop-Butyl Herbicide?
Cyhalofop-butyl is a systemic post-emergence herbicide from the aryloxyphenoxypropionate family, which is used for controlling annual and perennial grass weeds in a variety of crops, including rice, wheat, barley, and maize. Its primary mechanism of action involves the inhibition of acetolactate synthase (ALS), an enzyme essential for the synthesis of branched-chain amino acids in plants.
Precautions For Using Cyhalofop-Butyl Herbicide
Cyhalofop-butyl is a herbicide. When using it, you need to pay attention to the following points:
Safety. Cyhalofop-butyl is highly safe for rice and is the only variety of aromatic oxyphenoxypropionic acid herbicides that is safe for rice. It can be rapidly degraded into a diacid state that is inactive for acetyl-CoA carboxylase in rice, so it is safe for rice.
Period of use. Cyhalofop-butyl is suitable for rice from flower bud to grain filling period, but the effect is slow and it usually takes 1 to 3 weeks to see the effect.
Method of use. Stem and leaf spraying should be carried out when weeds in rice fields are 2-3 leaves, and fine droplets should be used to ensure uniform spraying. The recommended water consumption is 20-30 liters/mu. Drain water before applying the medicine so that more than 2/3 of the stems and leaves of the weeds are exposed to the water surface. Irrigate within 24 to 72 hours after applying the medicine, and maintain a 3-5 cm water layer for 5-7 days.
Precautions for mixing. Cyhalofop-butyl should not be mixed with some broadleaf herbicides to avoid reducing the efficacy. Suitable herbicides for mixed use include isothiocarb, cypermethrin, pretilachlor, pendimethalin, butachlor, quinclorac, oxadiazine, and fluroxypyr. However, 2,4-D-butyl, 2-Methyl-4-chloro-4-thiazolin, sulfonylureas, and methicillin and cypermethrin may produce antagonistic effects when mixed.
Avoid environmental pollution. Cyanosulfuron is highly toxic to aquatic arthropods and should be avoided from flowing into aquaculture sites.
Application environment. The temperature should not be too high when applying the pesticide, because cyhalofop-butyl is highly volatile, and high temperatures will lead to loss of efficacy.
Analysis of the efficacy of Cyhalofop-Butyl Herbicide
Cyhalofop-butyl herbicide is a broad-spectrum, powerful herbicide that can effectively kill various harmful weeds. Specifically, its efficacy is manifested in the following aspects:
Rapid weed killing
Cyhalofop-butyl herbicide can quickly penetrate into weed cells, destroy their membrane structure and biological metabolism, and thus quickly kill weeds.
Broad-spectrum weed killing
Cyhalofop-butyl herbicide has a significant killing effect on various weeds, especially those weeds that are resistant to other chemical herbicides, such as bindweed, sedge, and sedge, which can be completely killed.
Prevent recurrence
Cyhalofop-butyl herbicide can penetrate deep into the soil and maintain the removal effect of haystacks for a certain period of time, thereby preventing weeds from growing again and reducing damage to crops.
Correct Use Of Cyhalofop-Butyl Herbicide
The correct use of cyhalofop-butyl includes the following points:
Use period and dosage: Adjust the dosage according to the growth stage of weeds. For example, in the 1.5-2 leaf stage of barnyard grass, use 40-50 ml of 10% EC per mu; in the 2-4 leaf stage of barnyard grass, use 50-60 ml of 10% EC per mu.
Application method: Stem and leaf spray should be used to avoid the use of poisoned soil or poisoned fertilizer.
Soil moisture: The soil should be kept saturated with water before application, and the surface water layer should be less than 1 cm or drained. The saturated field water holding capacity of dry nursery fields or dry direct seeding fields can ensure vigorous growth of weeds, thereby obtaining the best efficacy.
Post-application treatment: Irrigate 24-48 hours after application to prevent new weeds from germinating.
Note: Avoid applying the pesticide during high temperature periods to avoid affecting the efficacy; use higher pressure and low volume spray; 10% Qianjin emulsion already contains the best adjuvants, so no other adjuvants are needed when using it.
How To Use Cyhalofop-Butyl Herbicide
In order to maximize the effectiveness of cyhalofop-butyl herbicide, you need to follow the steps below:
Choose the right time
Generally, cyhalofop-butyl herbicide is best used in spring or late summer and early autumn, when weeds grow most vigorously and the effect is best. Use it with caution in seasons with extreme temperatures (high temperature, low temperature, etc.) or excessive rain.
Protect surrounding crops
When using cyhalofop-butyl herbicide, you must pay attention to protecting surrounding crops and try to avoid dripping and loss of the agent to cause damage to the surrounding environment and crops.
Use the agent correctly
Use cyhalofop-butyl herbicide correctly according to the instructions of the agent, and do not use it in excess to avoid poisoning crops, beneficial insects, and harmful microorganisms.
Cyhalofop-butyl herbicide is a very effective chemical herbicide that can effectively kill various weeds, but at the same time, you also need to pay attention to safety and correct use methods during use to avoid unnecessary harm and losses.
What is Organophosphorus Insecticides?
Organophosphorus insecticides are a class of chemicals that were extensively used as insecticides, acaricides, and nematicides in agriculture, public health, and residential settings. They function by inhibiting the enzyme acetylcholinesterase (AChE), which is vital for the proper functioning of the nervous system in both insects and mammals.
Mechanism of action of Organophosphorus Insecticides
Inhibit The Activity Of Cholinesterase
The mechanism of action of organophosphorus insecticides is to inhibit the activity of cholinesterase, which is an irreversible inhibition.
Organophosphorus insecticides are a widely used class of agricultural insecticides, most of which are highly or moderately toxic, and a few are low-toxic. They are used worldwide to control plant diseases and insect pests. The main toxicity of organophosphorus insecticides comes from their inhibitory effect on acetylcholinesterase, which is a neurotoxic effect. By inhibiting the activity of cholinesterase, organophosphorus insecticides prevent the hydrolysis of acetylcholine, causing acetylcholine to accumulate in the synaptic cleft, thereby affecting the conduction of nerve excitation. This accumulated acetylcholine continues to act on the posterior membrane, keeping the insect in a state of continuous excitement, and ultimately causing the insect to spasm, paralysis and death.
In addition, the mechanism of action of organophosphorus insecticides also involves interaction with the active center of acetylcholinesterase, which is mainly composed of amino acids such as histidine and serine. Organophosphorus pesticides bind to these amino acids to form stable complexes, thereby inhibiting the activity of acetylcholinesterase, preventing it from hydrolyzing acetylcholine into acetic acid and choline, causing acetylcholine to accumulate in the body, affecting the normal physiological activities of insects, and ultimately leading to their death.
In general, organophosphorus pesticides inhibit the activity of cholinesterase, prevent the hydrolysis of acetylcholine, cause acetylcholine to accumulate in the body, thereby affecting the nerve excitation conduction of insects and achieving their insecticidal effects.
What Are The Characteristics Of Organophosphorus Insecticides
Most varieties of organophosphorus insecticides have acaricide effects, so they are also called insecticides and acaricides, but for convenience, they are all called insecticides below.
The research on organophosphorus insecticides in my country began in the early 1950s. Currently, there are about 30 varieties in production, as well as organophosphorus fungicides and herbicides.
(l) The toxicity to pests (including mites) is stronger than that of organochlorine insecticides, higher than or equivalent to carbamate insecticides, but lower than that of pyrethroid insecticides. Generally, 50 grams of active ingredients can be used in the field.
(2) The insecticide spectrum is wide or narrow. Trichlorfon, malathion, etc. have a wide insecticide spectrum and can control a variety of agricultural pests, sanitary pests, and livestock and poultry pests. Some varieties have a very narrow insecticide spectrum and are very selective. For example, aphidicide is only effective against aphids, which is very beneficial to protecting beneficial insects and natural enemies. Some varieties, such as phoxim and dichlorvos, have a short duration of effect and are very suitable for use on fruits, tea, vegetables, and mulberry trees that can be picked at any time; some other varieties, such as methyl isoflavone, have a duration of effect of up to 1-2 months and are suitable for scab-prone crops such as cotton and hemp and for the prevention and control of underground pests.
(3) Diverse insecticide modes can meet various needs. Most varieties have contact and stomach poisoning effects; some varieties have fumigation effects such as dichlorvos; some varieties have inhalation effects and are good systemic insecticides, such as dimethoate; and more varieties have varying degrees of infiltration effects. Therefore, it can meet the needs of various uses and has a variety of application methods.
(4) Generally, when the temperature is high, it shows a higher insecticide efficacy, which is called a positive temperature coefficient agent.
(5) Pest resistance develops slowly. Organophosphorus insecticides have been widely used for decades. Some varieties, such as trichlorfon and dichlorvos, are still widely used and the effect is still very good. This shows that the development and development of pest resistance to organophosphorus insecticides is slow. The cross-resistance between varieties is not very obvious. Therefore, when pests develop resistance to a certain organophosphorus insecticide, another (or even several) organophosphorus insecticides can be found to replace it.
(6) Toxicity varies greatly. Some varieties have very low toxicity, such as malathion and phoxim; but most varieties have high toxicity, and some varieties are highly toxic, such as chlorpyrifos. Some of these varieties have been banned by the state.
(7) Easily degradable (decomposed into non-toxic substances), with little pollution to the environment. They can be metabolized and detoxified in plants, and can be decomposed on the surface of plants by sunlight, wind and rain, so the residue in agricultural products is low. It is easily hydrolyzed in soil or water, causing little environmental pollution. It is easily metabolized and degraded in animals and excreted, without accumulation and no cumulative toxicity to humans.
(8) There are specific antidotes for highly toxic species, such as pralidoxime, whose detoxification ability is unmatched by any other type of pesticide.
(9) It is generally safe for crops. It does not cause pesticide damage to crops at the general insect control concentration (dosage). Some specific crops are very sensitive to individual pesticides, such as sorghum, which should avoid the use of trichlorfon.
(10) Most varieties are easily decomposed when exposed to alkali, so care must be taken when mixing them.
Organochlorine, organophosphorus, carbamate and pyrethroid are the four main types of pesticides. Due to residual toxicity and impact on the environment, most varieties of organochlorine insecticides have been banned one after another. Organophosphorus and carbamate have many similarities in toxicity, toxicity, and impact on the environment, but organophosphorus insecticides are cheaper. Organophosphates are less toxic to pests than pyrethroids and more toxic to humans and animals than pyrethroids, but they have advantages in terms of drug resistance, usage methods, and application scope. Therefore, as highly toxic varieties are banned or restricted in use, low-toxic organophosphate insecticides still occupy an important position in the entire insecticide class.
Advantages Of Organophosphorus Insecticides
There are many varieties and a wide range of applications. Most organophosphorus insecticides have broad-spectrum insecticidal effects, and have killing effects on mosquitoes, flies, ticks, mites, lice, bed bugs, etc.
Insecticidal effect; has high efficiency and quick killing performance, and produces less resistance or cross-resistance. Organophosphorus pesticides are highly toxic to pests (including mites), and most varieties have high efficacy and low concentration. Generally, the effect is better when the temperature is high. Its insecticidal mechanism is to inhibit the activity of cholinesterase and poison the pests. The disadvantage is that it is generally toxic to humans and animals, has a short residual period, and is easily degraded in the outside world or in animals; it is easy to decompose and fail under alkaline conditions (except for trichlorfon). During long-term storage, some organophosphorus pesticides It can gradually decompose and fail. Some varieties of organophosphorus pesticides are highly toxic to humans and animals, and if they are used improperly, poisoning accidents will occur.
