As for the pest thing, it's all over the job. Look.Mao.Line.Chinese.Text.Net

If you want to talk about the prevention and control methods of rice borer, there are actually a lot.

Chemical pesticides are the most direct means, and they are also an indispensable agent for the control of insect pests, especially in the event of sudden diseases, the control effect of chemical pesticides is very obvious.

However, for Jiagu agricultural materials, we should pay attention to the selection of pesticides, and we should focus on high-efficiency and low-toxicity varieties. And when using it, it is necessary to send technical personnel to guide, be sure to pay attention to the dosage and concentration of the agent, and it is best to pick and treat when the pest is small.

The adoption of physical control is also one approach. Adults can be trapped by installing frequency-vibrating insecticidal lamps, or by placing traps with sexual attractants. However, this is a measure that can only be taken at the beginning of the emergence of adult rice borer, and now it is mostly larvae, which is not applicable!

Biological control methods are naturally the most environmentally friendly.

There are many natural enemies of rice borer, such as red-eyed wasps, black egg wasps, and rodent wasps in the egg stage, and larvae have parasitic natural enemies such as small cocoon wasps, pathogenic fungi, bacteria and nematodes.

Therefore, natural enemies can be used to control the damage. Maintain natural enemies in the field such as frogs, black wasps, and rodent wasps, and give full play to the natural pest control role of natural enemies; or cultivate insect trapping plants to trap borers, and cultivate perennial plants such as vetiver and Sudan grass on roads, ditches, and field edges to trap and kill borers.

But at present, biological control can only be used as an auxiliary means at most - not to mention the input, the effect is too slow, and when the biological control takes effect, it is estimated that the rice borer has become a disaster, and the daylily will be cold at that time.

Of course, there are theoretically the most perfect microbial pesticides, because the effect of microbial pesticides is relatively strong, and the toxicity is small, basically no residue, and it should be vigorously used in high-quality rice.

Except for the price!

Farmers who work with Jiagu Agricultural Materials shake their heads like rattles when faced with the bill for microbial pesticides – the price is too high to be taken into account. See. Wool, Chinese net

Therefore, in summary, Jiagu agricultural materials can only serve farmers with chemical pesticides, and the other is supplemented by cultivating insect-trapping plants on the edge of the ridge to trap and kill borers.

Of course, Jiagu agricultural materials can only take into account the growers who have reached cooperation with the company, and other "retail investors" will depend on the government.

Insect control can be said to be a war between humans and pests for survival resources. War requires a high degree of organization and discipline, and the government is the most direct and effective organization and commander, especially in small-scale peasant economies, which should only be strengthened, not weakened.

Therefore, Jiagu Agricultural Resources also cooperates with the government and the Jiangyou Provincial Government to suggest or exchange relevant information, and try to implement unified prevention and control and eliminate dead ends in prevention and control work.

At this time, the overall effectiveness of the process of agricultural industrialization and large-scale control of pests and diseases and ecological control can be reflected.

Jiagu's Xianming rice planting base in Nankai City, Min Province, is next door to Jiangyou Province, but when Jiangyou Province is facing the threat of rice borer disaster outbreak, Nankai City is basically unfazed.

The cultivated land in Nankai City has been included in the unified management of Jiagu, which not only exterminates insect eggs in winter and spring ploughing, but also promotes the "duck-rice symbiosis" model on a large scale.

Even if there are fish that slip through the net, Jiagu uses microbial pesticides such as Bacillus thuringiensis for prevention and control, which is basically foolproof - the local tyrant is qualified to be capricious.

In fact, just seeing the frogs in the rice fields of Xianming is enough to leave the insect pest behind. Most of the frogs' food is eaten by pests, so Kaya puts a moderate amount of frogs in the rice fields, as long as the number of frogs is sufficient, it is better than all pest control methods.

Of course, looking at the whole country, chemical pesticides are still the absolute first choice.

Pesticides save an average of 50 million tons of grain, 15 million tons of vegetables and 6 million tons of fruits for China every year...... Reduce direct economic losses of more than 100 billion yuan, from the perspective of input and output, every one yuan of pesticides used, can obtain direct economic benefits of 10 to 20 yuan.

From these data, it can be seen that without the guarantee of chemical pesticides, our agricultural food security and grain self-sufficiency cannot be achieved at all.

Even Jiagu can only admit that at the current level of scientific development of plant protection, chemical control is still the most convenient, stable, rapid, effective and cheapest means of control, especially when encountering sudden and invasive biological disasters, there is no control method that can replace chemical pesticides.

Although in order to reduce the use of pesticides, both Jiagu and the country are vigorously promoting integrated crop pest control technology, fully adopting green prevention and control technology, and comprehensively using biological, physical, cultivation and other measures to control pests and diseases.

However, with the exception of local organic agricultural production and a small number of forest pests and diseases, it is unrealistic to rely only on natural enemies to control pests and diseases, both at home and abroad.

As for the toxicity that everyone is generally worried about?

In China, most people's minds of pesticides actually refer to insecticides, especially highly toxic organophosphates and other products. But you should also know that pesticides also include fungicides, herbicides, plant growth regulators and other products. Nowadays, the toxicity of many pesticide products is actually lower than that of table salt.

Moreover, China is at the forefront of the world in banning and eliminating highly toxic pesticides, and the banned varieties are the most in the world. Therefore, the safety level of pesticide products is actually getting higher and higher.

It is only in rural areas that pesticide applicators are the most affected to their health because of their direct exposure to pesticides.

Normal application generally does not produce poisoning, and most of the poisoning symptoms are not taken necessary safety protection measures when applying pesticides. In the same way, when applying pesticides correctly, most of the pesticide application rates are mostly 5~10 grams per mu, and even if there are residues, the residues are very small - it has been reported in the literature that even if there are pesticide residues, its toxicity is much lower than the toxicity of rice burning.

Well, the kind of farmers who don't follow the standards at all and use pesticides as water are not in this category.

......

In short, under the organization of Jiagu and the government, the less toxic pesticides were selected, and under the guidance of technicians, the rice borer was sprayed correctly, and the outbreak trend of rice borer in Jiangyou Province was quickly suppressed.

The reason why it is suppressed and not all controlled is because of resistance!

In the past, overapplication accelerated the development of rice borer resistance. In Jiangyou Province, it was found that rice borer had different degrees of resistance to commonly used pesticides such as insecticidal double and insecticidal single, the control effect decreased, the dosage of pesticides doubled, and the amount of residual insects increased.

At this time, it is necessary for someone to cover the last coffin board for the rice borer.

"The needle falls on the dust array (second order) trigger, the main gold system, and the range is twenty kilometers away. Effect inhibition, trapping killing. Creatures are in array, either inhibiting or trapping. ”

This is the tenth spirit array of the Qi Zheng Society, and it is also the first "killing array" that directly targets creatures!

As can be seen from the effect, this spirit circle locks on a creature's specific frequency, either encloses the creature in a range, or directly erases it spiritually.

Oh my God, what a "murderous" spirit array!

After Qi Zheng inspected the grain-producing areas of Jiangyou Province all the way, good guys, the rice borers who had been poisoned by pesticides could not bear the extermination from the soul in the end, whether it was insect eggs, larvae, or adults, all of them were exterminated.

The person who opened the hanging waved his sleeves, leaving "corpses all over the field".

In this wave of tragic "worm" blows, the few survivors who are "shivering" are left behind, even if they are allowed to grow in the future, they will not be able to recover to their original population size for seven or eight years.

In the next ten years, Jiangyou Province at least doesn't need to worry about rice borer pests, so it's still cool!
