Autumn is a season of harvest and re-sowing. For farmers in most areas, the corn, peanuts, sweet potatoes, etc. grown in the field are about to enter the ripe harvest period, and after these crops are harvested, they must be fertilized to prepare for the planting of winter wheat.
In the planting and management of wheat, in order to reduce the diseases and insect pests at the seedling stage of wheat, our peasant friends must seriously and strictly do a good job in the treatment of wheat before sowing, not only through the selection of seeds and sunning seeds to enhance the activity of seeds, improve the germination rate of seeds, but also through the use of fungicides, insecticides for impregnation seeds to prevent and control wheat diseases and insect pests, so as to ensure that wheat can achieve the purpose of increasing production and income in the later stage on the basis of smooth emergence of seedlings, robust growth, and fewer diseases and insect pests.
Although our farmer friends all know that wheat needs to be seeded with drugs before sowing, but many people have great misunderstandings in the choice of drugs, drug use and mixing methods of wheat seeding, if the drugs or methods of wheat seeding are improper, not only can not effectively control pests and diseases, increase production and increase income, but will also adversely affect the growth and development of wheat, and when it is serious, it will directly cause wheat yield reduction!
Therefore, in order to help everyone correctly understand and carry out wheat seed mixing work, today's agricultural technology small basket has specially written an article on wheat seeding, including: the classification and selection of wheat seeding agents, the use of wheat seeding agents and precautions, and how to distinguish the true and false advantages and disadvantages of wheat seeding drugs.
<h1 class = "pgc-h-arrow-right" >, wheat drug seed mixing purpose, seed mixing drug classification</h1>
1. The main purpose of wheat seed mixing is to control diseases and insect pests at the seedling stage
In general, wheat seeding is mainly to control the seed-borne diseases, soil-borne diseases, underground insect pests and a small number of aboveground diseases and insect pests at the seedling stage of wheat, and secondly, to promote the better germination of wheat seedlings, such as the use of phenylmethicazole, pyrimitrile, pyrrotrile, pentazole and other fungicides for seeding, to control the root rot, striated blight, smut disease, total erosion disease and other major diseases on wheat, such as the use of imidacloprid, thiamethoxine and other insecticides for seeding, which can effectively control aphids, gray planthoppers, golden needle worms on wheat. Insect pests such as grubs and caddisflies, such as the compound use of fungicides and insecticides or the use of compound drugs containing both fungicides and insecticide active ingredients, while preventing diseases and insect pests on wheat.
2. Common dosage forms and classification of wheat seeding drugs
At present, the agricultural market can be used to mix wheat with more dosage forms and types of drugs, in the dosage form is generally suspended agent, emulsion, wettable powder as the mainstay, in the active ingredient can generally range a single fungicide (such as the most commonly used phenylethocyclazole, clonylonitrile, pentazole, thiafromamide, etc.), a single insecticide (such as the most commonly used imidacloprid, thiamethoxazine, etc.), both bactericidal and insecticidal dual effect of the compound agent (using the above fungicides, insecticide compound drugs) three.
<h1 class="pgc-h-arrow-right" > second, how should we farmers choose the right wheat seeding agent for themselves? </h1>
When choosing wheat seed mixing drugs, on the one hand, we should pay attention to the selection of seed mixing drugs according to the types of diseases and insect pests that often occur in their own field plots, if the types of diseases and insect pests that occur on their own wheat are mainly diseases or the occurrence of insect pests is relatively light, then when choosing seed mixing drugs, it is necessary to use fungicides as the mainstay, insecticides as a supplement or the use of fungicides and insecticide compound drugs, if the types of diseases and insect pests that occur on their own wheat are mainly insect pests or the occurrence of diseases is relatively light, Then in the choice of seed mixing drugs to insecticide-based, fungicide as a supplement or the use of fungicides and insecticide compound drugs, if their own wheat often appear diseases and insect pests mixed phenomenon, then in the choice of seed is based on the type of pests and diseases targeted at the same time to select fungicides and insecticides, or directly choose to buy can control diseases and insect pests at the same time compound seeding drugs. In general, the use of suspension agent drugs is simple to operate, but the water solubility and efficacy are not very good; although the emulsion drugs have good water solubility and efficacy, but if it is not used properly, it is easy to lead to drug damage after wheat seeding; and powder drugs, one of the most likely problems when mixing wheat seeds is that the problem of uneven drug seed mixing will occur.
In terms of wheat drug seeding control and pest control, the two most commonly used and most used drugs are imidacloprid and thiamethoxine, although these two fungicides belong to the nicotinic insecticides with strong endogenous activity, but thiamethoxine is not only in the drug activity, water solubility, efficacy duration, insect control effect and drug resistance, etc., its use effect is better than imidacloprid, you may wish to try it yourself.
In terms of wheat drug seeding prevention and control diseases, the most commonly used and best used fungicides are mainly bacteriocrine nitrile, phenylethocyclazole, pentazole, thiofuranamide and other drugs with good systemic activity, in addition to plesimate, Fumei bis, jingjia cream, etc., we can flexibly choose according to their actual needs, such as the prevention and control of wheat total erosion disease can use phenoxymethmethicazole compound chlorobacterium nitrile, the prevention and control of wheat root rot can use phenylmeth methylcyclonazole and the like.
In terms of wheat drug seed mixing and disease prevention and insect pest compounding drugs, the mainstream products on the market are basically the use of the fungicides and insecticides introduced above as the main active ingredients of the drug, and then the fungicides and insecticides are compounded and produced in different proportions.
<h1 class="pgc-h-arrow-right" >3. How to select and distinguish the quality of wheat seeding drugs? </h1>
There are more wheat seeding drugs on the market, and they are also more chaotic, both high-quality products of large manufacturers with genuine and remarkable effects, and some bad manufacturers induce farmers to buy fake, fake, fake and inferior products at low prices. So, how should we farmers and friends choose and distinguish when purchasing wheat seeding drugs?
1, try to buy well-known products of large enterprises, do not greedily buy small manufacturers products from unknown sources. The products of large manufacturers in the use of mobile phones on the Internet can be related to the enterprise and product information, although this kind of product is slightly more expensive, but it is expensive in the output quality quality is very reliable; small manufacturers or unknown sources of products, with mobile phones on the Internet is generally difficult to search for related enterprises and product information, such products in addition to cheap prices, in terms of quality, efficacy and other aspects are useless. In short, expensive is not necessarily 100% good, but the price is very low must be 100% bad.
2, counterfeit and inferior wheat seeding drugs generally have a relatively strong pungent, dazzling smell, and after seed mixing, often appear in the seed surface attachment uneven, color shades of inconsistency, and in the seed after the seed drying attached to the surface of the drug often appear dust off the phenomenon, such products must not be purchased.
3, when buying wheat seeding drugs or seed mixing agents, you must ask the store for the "three certificates" formalities and documents for the registration and filing of the product, if the other party cannot come up with the relevant formalities, such products must not be bought, otherwise who buys who will suffer losses and be deceived.
4. After purchase, we must let the store issue invoices, receipts and other supporting materials to prevent the drug from being unqualified and unable to protect rights normally after burning.
5, the wheat seeding drug to buy home to do a seed seeding after the germination test, if found that the germination of seedlings abnormal or non-germination, not out of the seedling phenomenon, such drugs can not be used again.
<h1 class="pgc-h-arrow-right" >4. How to correctly use drugs for wheat seeding? What problems should be paid attention to when mixing wheat drugs? </h1>
1, according to the use of seeding to choose the type of drug to mix, the prevention and control of diseases to choose bactericidal drugs such as bactericidal drugs such as bactericidal drugs such as bacteribacteritrile, phenoxymethazole, and pentazole for pest control, such as imidacloprid, thiamethoxine, etc., while preventing and controlling diseases and insect pests, choose to use fungicides and insecticide compound drugs; if there is basically no disease and insect pest occurrence in their own fields, just to promote better germination of seedlings after wheat sowing, then plant growth regulators, foliar fertilizers, etc. can also be used to impregnate seeds, such as sodium compound nitrate.
2, wheat in the drug seed mixing, if both the need to use insecticide seeding, but also need to use fungicide seeding, then must be in accordance with the first mixing emulsion and then powder, first use insecticide seeding pile absorption for 2-3 hours, and then use fungicide seeding sequence, fungicide seed mixing after the seed is simple ventilation and shade should be quickly sown.
3. When wheat is used in drug seed mixing, it is best to mix it now, and it cannot be prevented for a long time, so as to prevent the reaction of the drug or the decomposition of the drug and reduce the effect of drug seeding.
4. When wheat is mixed with drugs, for seeds that have been drug-mixed or have been coated with drugs, it must not be re-seeded, otherwise it is easy to cause drug burning or seedling burning.
5, wheat seeding drugs are not used as much as possible. When mixing wheat with drugs, it must not be based on experience to "estimate the use of drugs" or blindly increase the dosage, must be used according to the dosage and concentration specified in the drug instructions, if the amount of drugs is too large or the concentration is too high, it is likely to cause the drug to burn seedlings, and if the amount of drugs is too small or the concentration is too low, it may lose the effect of drug seed mixing.
6, wheat seeding of the drug is not the more the better. Under normal circumstances, wheat seed mixing can choose a fungicide and insecticide respectively, if too many types of drugs are used, it is easy to affect the normal germination of wheat seeds due to unknown reactions of different drugs.
7. Wheat medicine should be appropriately mixed in advance when mixing seeds, and after seed mixing, it should be placed in a cool and ventilated place to dry in the air, on the one hand, the drug forms a permeable protective layer on the surface of the seed, and on the other hand, it prevents and controls the external high temperature and strong light directly hitting the drug and causes the drug to decompose and fail.
8, wheat drug seed mixing should be serious, uniform, comprehensive, meticulous, if the mixing is uneven, it will provide opportunities for diseases and insects to invade the wheat seedlings, if there is a condition, you can directly purchase the wheat seeds that have been coated with seed coating or use special seed mixing machines for uniform seed mixing.
9. Although wheat drug seeding can prevent and control some diseases and insect pests, for wheat planting areas with serious underground diseases and insects, in order to avoid the damage of wheat seedlings, it is recommended to take the method of drug seed mixing + drug soil disinfection and sterilization and insecticide treatment, so as to achieve the best disease and pest control effect.
In addition, if you do not have a good grasp of the wheat drug seed mixing technology, it is recommended that you directly choose the finished wheat seed coated by the drug seed coating agent, which can minimize the risk caused by improper drug use.
