Whether grapes can be bagged without spraying pesticides. Urgent .

It is best to spray pesticides once before bagging, including two types of pesticides for disease prevention and insect control. After such a long time in the paper bag, it is inevitable that pests and diseases will occur, and it is safe to spray pesticides once. As for what kind of pesticide is not rabbit dead dog cooking, as long as it is a medicine that can be used on vegetables and fruits, it can not be used with banned high toxicity and high residues and three pesticides, the growth period is so long, the pesticide is basically degraded.

It is better to bag early from the beginning of the fruit set.

I suggest that you spray 800 times of the new high-fat film at the grape young fruit stage and fruit expansion stage, which can play the role of liquid film bagging, which will not affect fruit respiration, prevent fruit rust, prevent fruit cracking, improve the coloring and brightness of the fruit surface, reduce residual toxicity and improve quality.

When spraying pesticides (insecticides, fungicides) and micro-fertilizers (calcium) on the fruit surface before bagging, add 700-800 times of the fruit tree health care transparent coating to spray the fruit surface and leaf surface together, and spray again at an interval of about 15 days, which can protect the active ingredients of the fertilizer before bagging and are not afraid of rain, and spray a total of 2 times before the paper bag. Inhibit the spread of germs, and at the same time improve the efficacy and fertilizer efficacy. Optimize fruit development levels.

As for the rest, I guess your main concern is the issue of residuals.

There is little chance that the grapes will come into contact with insects, birds, and other factors after you bagged. If spraying is required, spray pesticides with high efficiency, low toxicity and low residue. This is very, very little residue, and it can be said that there is basically no residue.

Before grape bagging, methoxyacrylate fungicides, carbendazim, chlorothalonil and so on are usually used, and the effect is good.

Grapes are generally before bagging, if the rain is relatively heavy during this period, the number of spraying should be appropriately increased. However, it is strictly forbidden to use Wangwang products before grape bagging to prevent fruit swelling. Also, if it is suddenly sunny after continuous rain, do not bag immediately, because it will aggravate the sunburn, and it will take a day or two for the fruit to adapt to the high temperature environment before bagging.

How many bags are put on the day, how much water must be poured on the day, and the main body is directly injured within the generation.

After the grape fruit is bagged, the fruit is in a small environment relatively isolated from the outside world, the temperature, humidity and humidity are relatively stable, and the light intensity is reduced accordingly, which delays the aging of fruit epidermal cells, cuticle and cell wall cells. At the same time, the fruit in the bag can avoid wind and rain, dust, chemical pollution, mosquitoes, flies and insect pests and bird damage. The bagged grapes have a smooth surface and a thick and uniform powder, which improves the appearance quality.

For bagging grape fruits, flower thinning and fruit thinning, inflorescence and fruit spike treatment should be carried out before bagging, which can greatly improve the excellent fruit rate of grape fruits; Secondly, grape fruit bagging can significantly improve the appearance quality and commodity value of grape fruits.

Spray the first half of the bagging.

After the grapes fall physiologically, when the fruit grows to the size of a bean, it is thinned and bagged immediately after the panicle. Before bagging, the fruit is fully sprayed with insecticides and fungicides allowed to be used in pollution-free food, and the fruit is sprayed on the same day after the liquid medicine is dried.

Before bagging, the grapes should be shaped and pruned, mainly to remove the overly dense branches, re-cut the weak branches, and do a good job of wiping and tying the vines. Grapes are left with 1 ear per new shoot, and 50 to 60 grains per ear.

In addition, soil improvement should be strengthened before bagging, and the application of high-quality soil miscellaneous fertilizer should be increased, and micro-fertilizers such as borax and zinc sulfate should be applied at the same time, and nitrogen fertilizer should be the main fertilizer for top dressing, so as to promote the early growth and development of fruit trees. The dry rock is generally watered before bagging to maintain the soil moisture content at 70 75% of the maximum water holding capacity in the field.

Summary. Hello yo, dear <>

I will help you solve this problem, you need to wait 6 hours for the liquid medicine to completely dry before bagging. Before bagging, it is mainly to inject a bactericide to prevent the disease in it after bagging. Basically, when the liquid is completely dry, it's time to bag.

After a long time, the bactericidal effect will be weakened, and the bagging germs will grow again. I recommend that you spray it with rare earth foliar fertilizer at this time (you can't use alkaline fungicides.) For example, Bordeaux liquid) can improve antibacterial ability, sweeten, color and precocious.

Grapes before bagging, if pesticides are to be applied. How long do I have to wait for bagging?

Hello yo, dear <>

I'll help you solve this problem, you need to wait for 6 or burn time to wait for the liquid to dry completely before bagging. Before bagging, it is mainly to inject a bactericide to prevent the disease in it after bagging. Basically, when the liquid is completely dry, it's time to bag.

After a long time, the bactericidal effect will be weakened, and the bagging germs will grow again. I suggest that the syndicate sell you at this time with rare earth foliar fertilizer spraying together (not alkaline fungicides. For example, Bordeaux liquid) can improve antibacterial ability, sweeten, color and precocious.

The pomace bagging period generally begins immediately after the fruit set is stable, the whole panicle and thinning is completed, and ends before the rainy season to prevent early infection and sunburn. To avoid the high temperature weather after the rain or the sudden sunny weather after the rain, it is generally necessary to dig for 2-3 days, and then the fruit is slightly adapted to the high temperature environment and then quietly bagging.

When is the best time to bag grapes? What pesticides should be used before bagging?

Hello, grape bagging should be as early as possible, generally after the fruit setting is stable, the whole ear and the end of grain thinning (the young grape fruit is the size of soybean grains) immediately begins immediately. Before bagging, permeable water should be poured once to reduce the temperature under the grape trellis; Before bagging, the whole park is sprayed with a fungicide, such as methyl thiobacterium deficiency, carbendazim, Shigao + pyrimycochlor, etc., and the bagging can be carried out after the liquid is dry.

Grapes are a delicious and nutritious fruit, but during the growth process, they are often attacked by pests and diseases, and they need to be sprayed to protect their growth and quality. However, there is one way to preserve the quality of the grapes without the need for pesticides, and that is bagging.

Bagging is to put a fine bag on the grapes, which plays a role in preventing insects and diseases. This avoids drug residues, reduces environmental pollution, and reduces safety risks to consumers.

However, there are also some drawbacks to the mountain spoiler bag. First of all, the cost is higher because of the need to purchase additional bags and manual bagging, which increases the production cost. Secondly, an excessively confined environment can also lead to damp rot of grapes.

Overall, bagging is a viable way to avoid drug contamination, but there are trade-offs between costs and benefits for both the producer and the consumer. From the perspective of environmental protection and food safety, bagging is beneficial and harmless, and it is also hoped that this good way of bagging will be more widely promoted and applied.

In order to prevent many diseases after bagging, spray the first half of the bagging. It is recommended that you choose products such as flusilazole (DuPont Fuxing), Yinfari, Suppression and Fastening, and Baitai. Generally, as long as the pesticides you use are low-toxicity and low-residue.

It is no problem to rinse it off repeatedly with water before eating.

Grapes generally begin to be bagged during the expansion period after fruit setting, mainly to prevent contamination of the fruit surface.

Now it is more popular to cultivate under canopies.

Grape bagging must be sprayed pesticides, in order to reduce the residue of the drug can be sprayed with some low-grade fungicidal pesticides, grapes in the long and large pearl size (small peanut beans the same) can be bagged, bagged grapes have no insect pests and bird pests, reduce bacterial infection, clean and hygienic, to achieve green food.

You can spray some bactericidal medicine so that there is no residue of the drug, and before the grapes are almost 15 years old, you can remove the bag, and the grapes will have a color when they are exposed to the sun.

Recommend Weinan Kao Technology Co., Ltd.'s film-free bag. Green environmental protection does not affect light and coloration.

1. This product does not belong to pesticides, micro fertilizers, does not contain hormones, is non-toxic, non-polluting, pH neutral, and can be mixed with various pesticides.

2. Evenly spray this product for 1 hour to form a film. After film formation, it is not afraid of rain, high temperature or other drug operations.

Grape bagging is to pay attention to those things! Do you know these basic methods? Very useful.

Carbendazim is sprayed once before bagging at the young fruit stage.

Grape bagging is better than early. However, it is not possible to do it too early, and it is generally bagged during the fruit expansion period. It was late, and some grapes had already been infected with germs, and it was difficult to eliminate them by spraying, and they were still multiplying in the bag.
