With the increase of temperature, a variety of pests and diseases began to enter a high incidence period, in the previous article, I talked about the more difficult to eliminate the control technology of aphids, today I want to share with you about the snail, slug control technology, this kind of insects in the summer is more harmful, must do a good job of prevention and control!
<h1 class= "pgc-h-arrow-right" > the super destructiveness of snails, and the right medicine is critical</h1>
A small snail, in its mouthparts, but there are tens of thousands of teeth, they mainly eat the leaves of crops, so that the leaves appear small holes, the quality of the decline, can not sell a good price.
Snails such as farmland pests, once the occurrence of the number is particularly large, summer rain more years, snails occur more, farmland soil is loose, humidity, more prone to snail hazards.
In addition, the snail also has the characteristics of diurnal and nocturnal, afraid of direct sunlight, so in the evening and even at night, it is the peak period of its activity, and the sun is strong at noon, and it hides in the shade of the field. Understanding these habits of it is the key to scientific prevention and control!
<h1 class= "pgc-h-arrow-right" > a special agent for the prevention and treatment of snails</h1>
Once the snail hazard occurs, timely medication is very critical, so which agents have a better effect? I'm here to share with you three ingredients that are very effective after practice!
1) Tetraacetaldehyde is a special drug for the prevention and control of snails and slugs, and is currently the most used. Tetraacetaldehyde often used in agricultural production has two dosage forms, granules and powders, such as 80% tetraacetaldehyde powder, 6% tetraacetaldehyde granules; powder spray effect is the best, some places will also be applied, generally in accordance with 750 times the use; granule sprinkling, the amount of per acre of land is about one kilogram; tetraacetaldehyde touch killing effect is better, so try to let the active ingredient contact with snails!
2) Quick extinction. Copper sulfate, this formula is also good for the prevention and treatment of snails. It is a compound of quick-extinguishing detergent and copper sulfate, and in production practice, it is found that the effect of this formula to eliminate snails is also good, and the quick-acting effect is more obvious. It is generally recommended to use a 74% quick extinction. Copper acetate powder 100-150g beat 30 kg of water to use.
3) Tetraacetaldehyde. Mesa. It's also a very efficient formula, and if snails that are resistant to tetraacetaldehyde, you can try this formula for faster results. 6% tetraacetaldehyde is generally recommended in agricultural production. Menapro granules 500-1000g are spread on an acre of land.
<h1 class= "pgc-h-arrow-right" > key points of prevention and control</h1>
1) Tetraacetaldehyde is very common in the market, and there are various price points, and the effect is uneven. High-quality tetraacetaldehyde granules, containing attractants, emetics, molding agents, etc., can be recycled (snails will spit out after eating), the tube time is long, but this high-quality tetraacetaldehyde, the cost is relatively high, 500 grams of price in 10-15 yuan;
And some of the poorer quality, 30 yuan can buy a barrel (5kg), but because there is no lure agent inside, the probability of the agent particles being swallowed by snails is reduced, and because there is no molding agent, it is easy to hydrolyze in rainy weather, so I recommend directly buying the high-quality tetraacetaldehyde effect of regular manufacturers here is better, do not covet cheap!
2) Medication time is very critical, especially the use of tetraacetaldehyde powder spray, must be used in the snail activity period, only contact with snails can be effectively killed; I recommend here that growers in the evening or evening medication is better. Of course, if granules are used, you don't have to pay too much attention!
The prevention and control of snails can not only rely on chemical agents, take some agricultural management methods, but also effectively reduce the incidence of snails, such as maintaining the hygiene of the field, timely cleaning of weeds in the field, etc., so that the environment is not suitable for snails to survive, and the number of snails is naturally reduced. Today's snail control technology is here, everyone has any questions can leave comments below the article!
