Hi everyone, this is Xiao Cui
.
In the last article, I introduced four common ways of action of pesticides.
Today I will continue to introduce you to the other eight ways of action of pesticides.
Because of the limited space, I will focus on the infertility and lure effects.
, Anti-feeding effect, and regulating effect
.
(5) After infertility pests take food or come into contact with medicaments, when a certain dose is reached, the pest’s reproductive organs can degenerate or inhibit the production of sperm and eggs, or kill the produced sperm and eggs, or destroy sperm and eggs.
The genetic material in the insects prevents the eggs from hatching normally, or poses as a sex attractant when the pests mate, so that the pests cannot find their mates and cannot mate and lay eggs.
The effects of sterilization are called infertility
.
Drugs with infertility are also called infertility agents, such as tepa, thiotepa, etc.
are commonly used infertility agents
.
Lithium-sulfur mixture (6) Attracting effect The medicament can attract pests to feed, mate, lay eggs and other activities in order to concentrate on destroying or investigating insect conditions.
The effect is called attracting
.
Medicaments with attracting effects are called attractants or preparations, such as poison baits, sex attractants, sweet and sour liquids and so on
.
At present, attractants are mostly used to control the adults of certain lepidopteran pests
.
(7) Antifeedant effect drugs that can destroy their normal physiological functions after being eaten by pests or other harmful organisms, eliminate appetite, make the pests refuse to eat any more, and eventually starve to death.
It is called antifeedant effect.
Drugs with antifeedant effect are called antifeedant effect.
It is called an antifeedant
.
Antifeedants are mainly used to control the pests of chewing mouthparts, such as antifeedant amines, which have a good antifeedant effect on many kinds of pests of chewing mouthparts
.
In addition, some insecticides that have been newly developed in recent years will also have a certain antifeedant effect, such as killing insect veins
.
Spray->
.
Chemical substances with regulatory effects are called plant growth regulators, or plant growth stimulators
.
At present, the regulators that are widely used mainly include regulators, triacontanol, ethephon, chlormequat, petroleum promoters, magnesium chlorate, naphthalene acetic acid, calcium cyanamide, etc.
.
In application, regulators are more stringent than pesticides, fungicides and other chemicals.
When using them, the variety, dosage, use time and frequency of the chemicals should be determined according to the physiological characteristics of the crop varieties, growth period, growth situation and climatic conditions.
Never use it indiscriminately, otherwise it will be counterproductive
.
Regeneratives are mainly sprayed or spot coated
.
The rice is ready to be sprayed.
Today’s sharing is over.
In the following chapters, I will continue to introduce the other four ways of action of pesticides.
Thank you for your collection and attention.
Thank you all
