Which active ingredients of pesticides are not smelly

Are you an insect killer? There are a lot of pesticides that kill that kind of insects and have no smell, like the acetamiprid and avermectin themselves that you said, there is no smell, mainly because the solvent in it smells bad after being made into a certain preparation. Knowing that you are killing that kind of bug can recommend the use of pesticide preparations that have no taste.

Abamectin, acetamiprid is basically not smelly, the reason for the big taste is not only the problem of the original drug, the liquid preparation contains more or less organic solvents, what xylene, methanol, toluene, acetone and the like are quite smelly. It is recommended that you use granules, powders, and suspension products, which will have a much smaller taste.

Aphids with imidacloprid, thiamethoxam, pymetrozine.

Moths use chlorantraniliprole (Kangkuan), fiproramide (Langge).

Bifenthrin is used for small green leaf cicadas.

What pests to target in order to know which type of pesticide to use.

The pungent smell of pesticides mainly comes from the benzene substances that exist as solvent additives in pesticides, such as benzene, toluene, xylene, methanol, dimethylformamide, etc., these low molecular weight solvents, low boiling point, volatile, toxic, large use not only causes environmental pollution, but also endangers human health.

In order to reduce the pollution of harmful solvents such as triphenyl, the Ministry of Industry and Information Technology, the Ministry of Agriculture, the Ministry of Environmental Protection and other management departments have introduced a series of important measures, achieved many scientific research results, and screened out a variety of environmentally friendly solvents that can replace triphenyl and other solvents

Bio-derived solvents: including vegetable oil, pine oil, animal oil, etc., can be used as pesticide solvents, but due to the complex composition, the stability is poor.

Mineral source solvents: including mineral oil, solvent oil, kerosene, etc., can also be used as solvents, but mineral oil itself is an active ingredient of pesticides, and solvent oil is insoluble in water, kerosene flash point is low, and the safety in production is poor.

Synthetic solvents: At present, there are some synthetic solvents with good solubility, high flash point and low toxicity, but most of them are still in the scientific research stage, and there is still a long way to go before the transformation of achievements.

At present, there are not many mature enterprises in the domestic benzene solvent substitute products, except for Hebei Tianfa Biotechnology Co., Ltd. in the processing of emulsifiable concentrate products, the use of vegetable oil solvents completely replaced benzene solvents, has not found other products that really use environmentally friendly solvents to completely replace benzene harmful solvents.

Part of the above information is from the second issue of "Modern Agricultural Science and Technology" in 2019 "Progress Status and Countermeasures of Substitution of Harmful Solvents in Pesticide Emulsifiable Concentrate", which is the latest research data, I hope it will be helpful to you.

At present, most of the pesticides used are chemically synthesized pesticides, which are toxic to diseases, insects and weeds, and are harmful to humans and environmental animals.

Herbicides have caused serious harm to the human body and other living organisms.

Acute poisoning According to the World Health Organization and the United Nations Environment Programme, more than 1 million people worldwide are poisoned by herbicides each year, of which 100,000 die. The situation is even more serious in developing countries. Nearly one million herbicide poisoning accidents occur in China every year, and more than 20,000 people die.

On September 24, 1995, ** TV reported that students at a school in Binyang County, Guangxi Province, had been poisoned by pesticides in 540 people after eating cabbage sprayed with highly toxic herbicides. This century is even more serious, and such events occur every year.

Chronic harm Chemical herbicides accumulate in the human body, although they will not cause obvious acute poisoning symptoms in the human body in a short period of time, but can produce chronic harm, such as: destroying the normal function of the nervous system, interfering with the balance of hormones in the human body, affecting male fertility and immunodeficiency. The chronic harm of pesticides reduces human immunity, thereby affecting human health, resulting in an increase in the prevalence and mortality of other diseases.

Carcinogenic, teratogenic, mutagenic The International Agency for Research on Cancer (IARC) has confirmed that widely used herbicides have obvious carcinogenicity based on animal experiments. It is estimated that the number of cancer patients associated with chemical herbicides in the United States accounts for about 20% of the total number of cancer patients in the country

Harm of herbicides to other organisms.

Direct Killing During the use of herbicides, a large number of non-target organisms will inevitably be killed, resulting in the death of natural enemies of pests and other beneficial animals. Large amounts of pesticides in the environment can also cause acute poisoning of organisms, resulting in the rapid death of biological populations.

Chronic hazards The bioaccumulation of chemical herbicides is the most serious form of indirect biological harm to pesticides, and herbicides in plants can be passed through the food chain and accumulate continuously, posing a potential threat to humans and animals and affecting ecosystems. Herbicide bioaccumulation is particularly pronounced in aquatic organisms, such as green algae can enrich 1 ppm of DDT to 220 times in the environment, and Daphnia can enrich DDT up to 100,000 times. The United States Ming Lake uses DDT to control mosquitoes, which contains 265 times the amount of green algae in the lake and finally 1700ppm in the carnivorous fish body, which is enriched to 85000 times.

Destroying the Ecological Balance There are many kinds of pests and natural enemies in the farmland environment, and under the natural environmental conditions, they are mutually restrictive and in a relatively balanced state. The extensive use of herbicides kills a large number of natural enemies of pests, seriously destroys the ecological balance of farmland, and leads to the enhancement of pest resistance. Pests that produce resistance to pesticides in China have spread all over grain, cotton, fruit, tea and other crops.

It has seriously polluted the ecological environment and destroyed the natural ecological balance.

There are many types of pesticide additives, depending on their role in the pesticide formulation. Some have a smell, some have a faint smell.

In general EC products, the solvents are xylene, methanol, esters, etc., which have a strong odor. Emulsifiers also have an odor because they contain a small amount of solvent.

In wettable powder WP, water-dispersible granules WDG, suspension agent SC and other pesticides, additives (fillers) include kaolin, clay, etc., and there is basically no odor.
