What should be paid attention to in the preparation of pesticides?

What should be paid attention to in the preparation of pesticides? (1) Select different varieties of insecticides, sterilizations and herbicides. Different types of pesticides have different control effects for different prevention targets.

2) Ensure the technical and quality of pesticide application. Pesticide application to select quality assurance sprayer equipment, accurate weighing of pesticides, this is also a key step to prevent diseases, insects and weeds, must be measured according to the pesticide manual, can not arbitrarily increase the dosage, especially herbicides, to prevent waste and environmental pollution to the natural environment, agricultural products. Do not apply a single pesticide for a long time, and scientifically standardize the mixing of pesticides to slow down the cause of drug resistance of Cordyceps sinensis.

3) Pay attention to medication safety. Ensure the safety of the observation period and scientific research on the application of pesticides to prevent human and animal poisoning. Pay attention to the cleaning of pesticide application equipment, and use cold water to dispense.

At this stage, some of the herbicides used in production and manufacturing are ultra-efficient, and once a certain pesticide remains in the pesticide application equipment, or the water used to prepare the pesticide is polluted by a certain pesticide, it is very easy to cause fertilizer damage to sensitive crops.

4) Ensure the quality of pesticides. It is noted that the professional pesticide marketing and sales department buys pesticides with three complete certificates.

Carefully read the manuals and labels on pesticide packaging, or under the guidance of local agricultural technology extension staff, clarify the dosage and operation methods. When configuring the liquid medicine, it is necessary to carefully calculate the amount of Chinese medicine preparations used per mu and the preparation of water to prevent frequent errors and omissions. Strictly in accordance with the prescribed amount of use, some large canned drugs, to the need for a measuring cup to choose, do not pour casually, can not use a bottle stopper to pour medicine or drink bucket dispensing.

You can't use waste water and river water to dispense medicine, you can't use a bucket containing liquid medicine to immediately go down to the ditch and river to collect water, you can't mix it with your hands, and if it is blocked by a sprayer, you can't blow it immediately with your mouth. Wear certain protective clothing when configuring and applying pesticides.

Be careful when dealing with granules and wettable powders to avoid dust flying and causing inhalation. The dispensing equipment must be of a special type, and it should be rinsed neatly after each use. It is not recommended to mix and match various drugs on the grounds of comprehensive prevention and control, and should be carried out under the guidance of agricultural technology extension workers if necessary.

If the systemic touches the alkaline pesticide or alkaline substance, it will dissolve quickly and be ineffective. The mixture of propanium emulsifiable concentrate and methyl parathion pesticide will cause fertilizer damage.

When dispensing, the sprayer should not be overfilled to prevent the liquid from leaking. Ready-to-use, a very small amount of leftover and waste liquid should be solved according to requirements, such as burial. You can't just pour it into the river. For expired pesticides, it is not necessary to put them into the chemical solution, otherwise there will be damage.

The precautions are that it must be configured according to the proportion, too much or too little is useless, it will not work, or you need to pay attention to the corresponding proportion.

The thing that needs to be noted is that 1 different types of pesticides can not be mixed, 2 to learn the first ingredient list, 3 pay attention to the dosage, 4 pay attention to the proportion of water, so as to prepare good pesticides.

It needs to be configured in accordance with scientific methods, and must pay attention to safety, pay attention to concentration, and match it in a normal way, and equip it according to the growth of plants.

Select drugs according to climatic conditionsSome drugs increase their efficacy or low sensitivity under high or low temperature conditions, which may cause drug harm or ineffectiveness, so we must choose pesticides reasonably according to different climates.

If the oily preparation is used under high temperature and scorching sun, it is easy to cause the leaves to burn and dry up. For example, Bordeaux liquid is easy to produce pesticide damage when it is applied on foggy days and when the dew is large.

It is necessary to choose the appropriate control agent according to the prevention and control objectives, any kind of pesticide has its applicable control range, and the use beyond the scope of prevention and control is costly, laborious and thankless! That is to say, in order to ensure the effectiveness of control, we should first determine the types of crop diseases, insects and weeds and the corresponding control measures. For example, when aphids, whiteflies, thrips and diamondback moths and other pests are mixed in the field, it is best to choose a combination of insecticides and insecticides that can treat a variety of insect pests, and the main control objectives should be determined at the same time, so as not to neglect one or the other.

To understand which pesticides can be mixed, which prohibition of mixed use of drugs should also be noted, some pesticides can be mixed, both parties are not affected, but some pesticides can not be mixed. For example, some nematicidal pesticides, such as nematode Bike, cannot be mixed with other fungicides. Like scabies, it is a pesticide to prevent scale insects, and this pesticide cannot be mixed with alkaline pesticides.

Therefore, in the pesticide operation, it is necessary to have a certain understanding of the property knowledge of the drug, and it cannot be mixed and mixed at will.

When choosing pesticides, we should focus on considering these situations in the actual production, before selecting pesticides, we should fully understand the control objects to be controlled, understand the occurrence categories and types of diseases, insects and weeds, and prescribe drugs according to insects and diseases. When selecting, it is generally necessary to consider the following aspects: (1) It is necessary to pay attention to safety, and the selected pesticides should not cause pesticide damage.

2) Choose pesticides with low toxicity and low residues, reduce pesticide residues and pollution as much as possible in use, and avoid damage to the ecological balance. (3) To ensure the control effect, choose high-efficiency agents to control the harm of pests and diseases. (4) Choose pesticides that are resistant to rainwater erosion, give full play to the efficacy, and minimize the number of medications.

5) Be heavy on ingredients and light on names, that is, mainly screen with the active ingredients of the drug, and don't be confused by some attractive names. (6) It is necessary to rationally select mixed pesticides, not only to give full play to the action characteristics of different types of pesticides, but also to avoid some negative effects of a single ingredient. (7) It is necessary to have a long-term and overall perspective, and not only focus on immediate and partial interests.

First of all, we should pay attention to the selection of the right pesticides, and we should also pay attention to the ingredients in the pesticides, and at the same time, we should also pay attention to the problem of proportioning when choosing acorns.

First of all, it is necessary to choose the right pesticide according to the crops of the liquid locust stool, and then you also need to pay attention to the appropriate concentration and travel agent, you must choose the right time to spray pesticides, to avoid the time when the temperature is relatively high, and when it is raining, at the same time, you should also choose some bright grades are safer and have better efficacy.

It should be noted that when only choosing, it is also pointed out that the rotten knowledge should look at the external packaging, and some pesticides with regular production dates and manufacturers should be selected, and at the same time, they need to be consistent with the roots in the process of use.

I rarely hear about buying pesticides online. I think buying pesticides online is the same as buying medicines online. For many people, it's better to go to a brick-and-mortar store.

I think online shopping is the general trend because the current crop profits are decreasing and producers should reduce costs. Online shopping can still reduce costs. Compared to other industries, our agriculture is lagging behind.

E-commerce in other industries is growing. Of course, the agricultural industry cannot refuse the Internet.

There is a big difference when it comes to buying pesticides online, so to speak, of mixed race. The proponents believe that buying pesticides online is much more expensive and can save money; Opponents argue that buying pesticides online doesn't see the real thing, and it's easy to be fooled by my experience of buying online! Online shopping is still very reliable!

First of all, most ** have their own brick-and-mortar store! No one is going to sell something on the internet that is not their main and immature product! Now the management of pesticides, fungicides, pesticides, etc. is very strict!

Online shopping is a cheap and risky business! I am a descendant of 70 years old. There aren't many online shopping, but there are less than 20 online shopping platforms.

Aside from **paying** a fee, I feel like I've never been cheated once, but because I want to be cheaper, I'll buy again after I've been fooled once. Let's not say whether it's reliable or not. Are we going to talk about whether people who buy pesticides buy pesticides online?

The reason is simple. We will give you a specific analysis. What is the reason?

A lot of people don't buy pesticides online.

Reliability is not a problem of the platform, but of the insiders. It's definitely fake. Many** reports say that a large percentage of counterfeit agricultural products are sold through e-commerce channels!

But this is definitely not a disaster. Many manufacturers have stores on e-commerce platforms, and I often order online. First of all, sometimes I don't want to buy pesticides online.

In fact, sometimes it is very inappropriate to buy pesticides locally. One is that the geographical location is too far. It is estimated that some people have to take the bus or drive themselves.

The other inconvenient one is that for our generation of online shoppers, I bought it at a local brick-and-mortar store. I bought a special herbicide for Aibo online. The trader is good.

Online shopping is a way to walk. As society evolves, it has to adapt to today's highways. **Merchants can buy in good faith and stay calm.

Of course, it is effective, the effect is very good, pay attention to the configuration of pesticides, pay attention to the acidity and alkalinity of pesticides, and pay attention to the ratio of pesticides.

I feel that the pesticides I have formulated are effective, and I feel that I need to pay attention to the safety aspects, operational problems, environmental problems, efficacy problems and spraying problems when formulating pesticides.
