What is the best pesticide for controlling Wang

In recent years, the application of regulators in agricultural production to control proliferation has been basically popularized in rural areas, and there are many varieties, such as chlormequat, triazoles, mepiidine, ethephon, etc.
, which are commonly used ingredients for prostration control products
.
The crops that farmers friends widely use control proliferation drugs include: field crops corn, wheat, peanuts, cotton, sweet potatoes, greenhouse strawberry vegetables, and some other crops.
Farmers also habitually choose proliferation control pesticides, and have a sense of dependence on control proliferation pesticides.
, And no longer consider agronomic measures such as strengthening cultivation management and medium element adjustment to control the growth of crops
.
This approach is wrong
.
In fact, the best pesticide for controlling Wangwang is to use no medicine for controlling Wangwang
.
There are three reasons: First, the long residual period of the wang-controlling agent in the soil will inhibit the growth of the next crop
.
At present, most people who promote and sell pesticides in rural areas talk about the benefits after using them, but avoid the problems that will arise after using them, or do not mention them to the farmers at all.
WeChat search for vegetable farming circles pay attention to join
.
For example, if your crop of wheat is sprayed with paclobutrazol for control, the pesticide salesperson will not tell you, it may affect the emergence and growth of corn planted after you harvest the wheat
.
In recent years, there have been incidents where the following crops do not emerge or grow up due to the spraying of herbicides and growth control agents
.
I remember that a serious incident occurred that year.
There was a boss who returned to the village to start a business and transferred thousands of acres of land to grow blueberries.
He did not know the use of the land in advance, which directly caused the fruit tree seedlings to be planted not long or dead, which led to a good plan.
Suffer a heavy loss
.
Second, it is difficult to control the time and concentration of the spraying of the anti-wang medicine
.
If the drug control time is wrong, the concentration is wrong, and the climate and soil moisture conditions are not considered comprehensively, it may control the growth and reduce production at the same time
.
For example, peanut control must be sprayed after most of the fruit has been needled
.
If you take the medicine to control the growth of peanuts during the peanut blooming period, the vegetative growth of the stems and leaves will be inhibited, the flowers will not bloom, the formation of fruit needles will be less, and the elongation of the fruit needles will be inhibited.
The needles are short, the fruit is thin, and the yield and quality are both It will have a great impact, and it is inevitable to reduce production
.
The third is that premature application of prosperous drugs will cause premature plant senescence
.
Science and technology is a double-edged sword.
For those new farmers who have the skills to manage, can comprehensively consider planting rotation, and avoid possible problems in advance, they can use pesticides to control the prosperity at the right time, and indeed use pesticides to control prosperity can save more.
Time seems to be more cost-effective than strengthening cultivation management and other agronomic measures
.
However, for those old farmers who have little knowledge of Kwangwang's products, the use of Kwangwang pesticides adds more risks and uncertainties
.
First, there must be a stance of avoiding prosperous drugs
.
Strengthen cultivation management and other agronomic measures, or use middle and trace elements to regulate and control prosperity
.
As in the past, when peanuts are grown in Jiaodong countryside, clearing the seedlings is actually one of the methods of manual management to control prosperity.
The root soil of the peanuts is removed to expose the two petals, let the sun shine, and the seedlings can be squatted.
It can both strengthen the seedlings and suppress the growth.
Prosperous
.
In order to save labor and effort, the current peanut planting technology has no clear squatting seedlings, but it is still effective to adjust the middle and trace elements such as boron, calcium, phosphorus, and potassium
.
For example, the combination of potassium dihydrogen phosphate and boron-calcium fertilizer can promote high yield and also achieve the effect of controlling prosperity without soil residue damage
.
Second, it depends on the weather conditions to choose the types of base fertilizer and top dressing
.
Farmer friends all have some farming experience in this area, for example, the winter is neither cold nor hot
.
The unusually warm winter climate makes this summer cool and rainy.
With plenty of rain, crops are prone to flourish.
In this case, urea (nitrogen fertilizer) and other fertilizers that can easily lead to flourish crops should be controlled as little as possible or not used as much as possible for reproductive growth.
Beneficial potassium dihydrogen phosphate can be used as top dressing and regulation and control
.
Third, we must look ahead and think about what to plant next crop before using the prosperous control medicine
.
The half-life of the proliferation control medicine is too long, it will continue to exist in the soil, and then be absorbed by the next crop, and continue to inhibit the growth of the crop
.
If everything is within the controllable range, and the crops are growing and imminent, it needs to be solved immediately, and it is not impossible to use it
.
But be sure to look at the time and use the right concentration
.
Fourth, according to the characteristics of different crops, select the best time and the most suitable prosperity control drugs
.
Each crop has its own drug resistance and preferences.
Pesticides that control corn may not be suitable for cotton, nor are they suitable for strawberries or other fruits and vegetables
.
What is suitable for the crop itself is the best
.
The time of using drugs to control prosperity is also very important.
For example, the best period for maize to control prosperity is 6-10 leaves
.
Fifth, we must master the "degree", use the manual + adjust measures to local conditions
.
The instructions for use of pesticides are only a reference indicator, especially when using pesticides to control proliferation, the appropriate dosage must be considered comprehensively according to the soil moisture in one's own soil, the degree of vigorous growth of crops, and future weather factors
.
For example, in arid areas and areas with heavy rainfall, the drugs used to control proliferation must be different
.
In short, farmers must not rely on the best pesticides to control prosperity in farming.
They must be based on management.
If they can be controlled by safe and natural agronomic management measures, they should not use prosperous drugs, especially those who understand prosperous drugs.
The few farmers must be more cautious
