For fruit trees, can pesticides, foliar fertilizers and fungicides be mixed?

Many of our growers, whether they are spraying pesticides or fungicides, like to mix foliar fertilizers and spray them together, thinking that they can kill multiple birds with one stone, but in fact, they may not be able to produce as effective as we imagined, why? Because not every spray is suitable for foliar fertilizer, not all pesticides can be mixed with foliar fertilizer.

Can foliar fertilizers be mixed with insecticides and fungicides?

Although foliar fertilizer is good, but it can not be used in a large way, to use foliar fertilizer as a base fertilizer, top dressing auxiliary, and can not be regarded as a main means, according to the absorption of nutrients is the main thing, foliar spraying plays an auxiliary role, if we use a gas in foliar spraying, it is likely to cause some serious consequences, such as the mancozeb we use this kind of fungicide, it itself contains manganese zinc foliar fertilizer, after using too much, manganese zinc poisoning will often occur, Most of the foliar fertilizer belongs to the compound type, most of the 16 kinds of large, medium and trace elements contain five or six kinds, if in addition, add some amino acids, etc., so that the composition is more complex, then the metal elements in the foliar fertilizer often react with pesticides.

In the process of use, if we find turbidity, precipitation, flocculent, insoluble, and chemical performance conflicts, the pesticide will fail, and the crop will be damaged.

We should pay attention to the order of pesticide and foliar fertilizer mixing, nutrient foliar fertilizer, it is in the form of ions, after the ion concentration is too high, it is easy to cause pesticides and these fertilizers to react with nutrients and precipitate, affecting the efficacy, therefore, when we mix pesticides and foliar fertilizers, we should first dilute the foliar fertilizer with water, then add wettable powder, then add suspending agent, then add water agent, and finally add emulsifiable concentrate, so that the order is mixed in turn, mixed well, stirred evenly, so as to reduce the possibility of precipitationThe risk will be relatively small, we must carry out secondary dilution before the pesticide is mixed, so that we can minimize the risk, when the foliar fertilizer and pesticide are mixed, it should be used with the mix, it cannot be said that it is useless this time, and it will be used again after a period of time.

They should not be mixed because the chemical composition in them is different, and if they are mixed together, they will have a chemical effect, which will cause damage to the fruit tree.

Yes, bai foliar fertilizer is a nutrient type of fertilizer, which is applied by spraying.

The leaves can be quickly absorbed back to supplement the nutrients required during the peak period of fertilizer demand. The main function of fungicides is to kill diseases caused by various bacteria and fungi on fruits and vegetables, and can improve crop quality.

When crops are diseased, fungicides need to be sprayed in time, and nutrients should also be replenished, so as to promote the rapid recovery of crop growth, which is also a common method in daily crop management.

Hello Bai? For your information:

Methyl Du tobuzin is a fungal agent.

Oxamine is. **DAO underground fungus drug return.

Methalamine is a fungal agent.

Silicones are additives.

Potassium dihydrogen phosphate is a trace element.

It is a plant regulator.

The name of the compound of Oxamyl and Jingjiashuang is Ruimiaoqing) It is recommended not to mix and use.

Thank you for your question.

Summary. Hello, happy to answer your questions.

Most of them cannot be mixed, except in exceptional circumstances. Because the metal elements in foliar fertilizer often react with pesticides, as long as there is turbidity, precipitation, clearing, and insolubility after mixing, the pesticide will fail, and the crop will be damaged.

<> foliar fertilizers should not be mixed with pesticides and fungicides. Most of the foliar fertilizers belong to the compound type, generally containing 5-6 kinds of elements and amino acids, hormones and other substances, the active ingredients are complex, and chemical reactions may occur after mixing with pesticides and fungicides, resulting in yellowing and redness of the leaves of crops.

<> most of the insecticides and fungicides can be used on fruit trees at the same time, but some insecticides and fungicides should not be used at the same time, such as carbendazim and thiophanate-methyl are fungicides belonging to the benzimidazole class, and they have a certain orthogonal resistance relationship, so these two drugs should not be mixed.

Normal can be compounded and sprayed, pay attention to chemical reactions and microbial preparations can not be combined with chemistry.

Fruit trees use fungicide fertilizer, and fungicides cannot be applied at the same time. Otherwise, the fertilizer will be sprinkled in vain.

Common fruit trees are: apples, pears, etc.

Apple production and cultivation conditions:

Temperature. The apple tree is a temperate fruit tree that likes low temperature and dryness, and requires no severe cold in winter and no scorching heat in summer. The suitable temperature range is the annual average temperature of 9 to 14, the extreme low temperature in winter is not less than minus 12, the maximum monthly average temperature in summer is not higher than 20, the accumulated temperature in 10 years is about 5000, the average temperature in the growing season (April to October) is 12 to 18, and the following low temperature of 1200 to 1500 hours in winter can successfully pass natural dormancy.

It is generally believed that apples can be cultivated in areas with an average annual temperature of up to 14. Apples have a longer natural dormancy period. If the temperature is high in winter and the low temperature required for the dormant period in winter cannot be met, the germination in spring will be uneven.

From the perspective of the regions with the most cultivated apples in the world, the average temperature of the coldest month of winter (January in the northern hemisphere and July in the southern hemisphere) is between minus 10 and 10 to meet the low temperature requirements of apples. The average temperature in January in all major apple-producing areas in China is within this limit. The average temperature is between 12 and 18 during the growing season (April to October) and between 18 and 24 in summer (June to August), which is ideal for growing apples.

In autumn, when the temperature is high during the day and low at night, the fruit has high sugar content, good coloring, thick peel, more fruit powder, and is resistant to storage.

Apples require about 180 mm of precipitation per acre during the growing season. In general, the amount of natural precipitation that can actually be absorbed by fruit trees is about 1 3, so that the precipitation during the growing season can be 540 mm, which is sufficient. Irrigation is needed in areas with precipitation below 450 mm from April to September, and precipitation is unevenly distributed in northern China, with 70% to 80% concentrated between July and August, and insufficient water in spring.

In inland areas with low precipitation, the amount of water is insufficient, so when choosing land for gardening, it is necessary to take into account irrigation conditions and moisture conservation measures, as well as drainage measures during the rainy season.

Sunshine. Apple trees are light-loving trees, and they can grow normally only when they have enough light. According to the determination of Shandong Agricultural University, the light compensation point of Jinguan and New Red Star in Tai'an area is 600 to 800 meters of candlelight, and the saturation point is 3500 to 4500 meters of candlelight.

In this range, the intensity of light increases and photosynthesis intensifies. Insufficient sunlight causes a series of reactions, such as long branches and leaves, weakness, poor resistance to diseases and insects, less flower bud differentiation, less nutrient storage, low flowering and fruit setting rate, root growth is also affected, fruit sugar content is low, and color is not good.

Soil. Soil has a great influence on the growth, yield, and quality of apples. The main factors are the soil layer, soil aeration, and soil quality. In conclusion, apples need to be deep, fertile, well-drained, rich in organic matter, slightly acidic to slightly alkaline.

Wind. High winds often have many adverse effects on the growth of apples, such as causing crown deviation, affecting flowering, pollination, damage to leaf organs, and fruit drop, so it is necessary to create windbreaks to establish apple orchards in windy areas.
