Premature and late disease of potatoes are serious diseases, both of which are characterized by folates and stem burns that seriously affect the production of potatoes, thus affecting income from cultivation. Since the symptoms of the two diseases are highly confusing and indistinguishable, which makes it difficult to combat them, the correct distinction between the early and late cases of the potato disease is of real significance in combating them。
Ii. Distinguishing between early and late diseases
Core distinguishing points: night disease with water immersion + high-wet leaves with cortex; early disease with small chords and clearly concentric threads。
Symptoms of the potato fever
Symptoms of the potato fever and tubers
Ii. Clearing the difference and making the field more aware of the disease
The high rate of destruction of leaves and troughs in the fields and in storage due to the late disease of potatoes is a devastating cobble disease that causes death and decay of potatoes leaves. Autumn potatoes have high hairs, first flower (in late september - mid-october) warmness matches and is highly explosive. Farmers are often confused with similar diseases, miss the window, fail to keep up with later controls and spread widely in a short period of time. The core of field outbreaks is induced by heavy rainfall, high humidity, mist weather and temperature (18-25°c)。
Iii. Distinguishing between early and late disease, selection is key to drug control
In response to the high incidence of fall potato disease, the prevention of early and late disease is recommended, and in the case of the discovery of a combination of two diseases in the field, a combination of specific drugs is required。
1) prevention options are: 75% 菌 醇 醇 醇 + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + 。 + + + + + + + + + + + + + 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。
2) options are available in the initial pharmacological programme: 50% fluorine cyanide dispersed granules in frosting spring + 32% in carbonazine, or 36% fluoride alkyl fluoride + 40% phenol sulfide or 75% fentanyl sulfide sulfide, rotation of the pharmacist programme, retardion of resistance。
Iv. 4 major differing advantages achievements and better prevention and response
According to the owner of the maung guang guang farming company, the effects and damage tests were carried out in his home before the frosting. With the use of frosting springs, the disease of the taco disease began to dry one day after the medicine, forming phnom penh, where the disease is no longer spreading. There were no spots on the tarp, and it was also clean, which was somewhat more effective than other infectious agents. The mix and safety of frosting is also high, and the rise of the platinum is more green。
She was happy to say that she had helped to control her disease, and now she is. “before the medicine is taken, the disease falls on the ground and 10 buckets of rotten fruit are taken and buried, and there was no control.” it is recommended to use frosting springs, non-proliferation of fruit and fruit, non-infection of plants, green leaves and clean fruit。
Taido wei's older brother, who grew in tunzhou in beijing, was affected by the heavy rains, which caused an outbreak of cuisine disease, resulting in minimal losses and a very good development。
In a self-impression, the ten-acre tomato farmer in huang hingsha, hunan city, laughed that the disease had not spread because the imported medicine could not be used. The effect of frosting is okay。
As a result of the joint efforts of the national channel partners, the frosting has not only performed well in the prevention and control of diseases such as tomato and ketchup, taco, clot, cassava and potato, but also in the fight against frosty diseases such as grape and cucumber. The general manager of guangdong zhuang biotechnology ltd., general commander lu, shared the view that frosto-chung had demonstrated excellent performance in the prevention and treatment of ovarian diseases such as tomato, taro, clot, potato and so forth, mainly due to product 4 differential advantages。
1) the selection of a 35% fluoride and 15% cyanide re-composing system for the fungicide of ovary disease. The scientific combination of the two active ingredients, with high co-toxic coefficients and high levels of active ingredients, is more significant and thorough in the prevention of ovarian diseases, such as the dysentery of potatoes。
2) the sulfluramid drug selected by the fung yung ying is derived from bayer shares and is of a higher purity, less impurity, better fungicide activity and more stable, and safer in the field. High levels of fluorine amphibian amphibian, which further enhances the thin-layer penetration of the agent, the internal insorption conductive capacity, can penetrate the potato blades, the skin tissue of the mandible skins, deep into the plant plant plant and eliminate the deep bacteria. Field visualization is characterized by rapid drying of the disease and faster disease control。
3) the application of a single-source membrane plating technique, carried by natural algae, can result in the formation of a layer of gas-enriched protective film on the surface of the taro platinum. Long-lasting resistance to infestation and the dual effects of early prevention and treatment of disease can also feed crops, repair damaged disease tissues, and help in the rapid recovery of the growth of the strains。
4) the frosting spring uses the ultra-micro-dry suspension process, where the finished particles are both fine and clean, and have the characteristics of extremely rapid water dissolution and even dispersing pharmacies. Sprays provide uniform coverage of the whole range of leaf blades and foliages of the crop, significantly increasing the adsorption rate and the efficiency of the drug. At the same time, the products fit all kinds of field application equipment, such as drones, sprayers, and so forth, and are easily operational, time-efficient and scale-appropriate for field planting。
