Yellowing of the tip of the turfgrass in summer What is the disease and what medicine is used?

In the summer, the tip of the turfgrass is downward, and I think that if I go to the pesticide department and ask for some other pesticides, it is likely to be the disease of premature aging.

During the turf management period, if not done properly, the green grass may become green and replaced by a decaying yellow. Here is a summary of some common causes of turf yellowing:

1. Insufficient light, hindering photosynthesis. Insufficient sunlight in the rainy season will hinder photosynthesis and reduce the function of roots, especially the lawn with too little fertilizer, which will affect the accumulation of carbohydrates by plants, hinder nitrogen metabolism, and lead to yellowing of the lawn.

2. Uneven fertilization, in the process of applying nitrogen fertilizer to the lawn, some lawns are yellowed due to excessive nitrogen fertilizer, and some lawns are yellowed because no nitrogen fertilizer is applied.

3. The absorption of nutrients is unbalanced, and the lawn appears yellow. For example, in the case of high lime application, magnesium deficiency also affects iron absorption; Too much potassium is used, which hinders the absorption of other salts.

4. Poor drainage, water on the ground, especially in the rainy season, the soil is too wet and causes yellowing.

5. If the grass is too low or the dead grass layer is too thick, it will usually lead to yellowing.

6. If the pruning is not timely, the lack of sunlight in the roots causes the lack of light yellow.

7. Pests are harmful, aphids, grubs and other hazards to the lawn cause yellowing of the above-ground part of the lawn.

8. Due to the presence of pathogenic bacteria, the function of the root declines and the absorption of iron is blocked, and the aerial part of the plant is yellowed.

9. Lack of necessary nutrients for the formation of chlorophyll, such as iron, magnesium, manganese, sulfur and other elements, of which iron deficiency is the main reason.

10. Lack of nitrogen, unable to form protein and yellowing.

11. Copper deficiency in the soil, copper is a trace element necessary for the growth process of the plant, once the copper is lacking in the soil, the turfgrass will yellow.

In summer, turfgrass tips are downward, and yellowing is due to grass blight, and some are causes, so you can ask the person who sells the medicine.

If it's not because of the drought, try watering.

Look for spots on the leaves, if there are any, it is likely that the roots of the seedlings are rotten and yellowed due to brown spot disease. It can be prevented and controlled with chemical agents, and the disease is sprayed with 25% powdery rust or hydroxyrust 1000 times plus 200 times of high lipid film during the peak of the disease; It can also be administered with 50% carbendazim or methyl tobuzine 800 times solution in combination with high-lipid membrane. It is recommended to use clover cross-planting to reduce germs.

: Lack of water and fertilizer. The lawn that has just been planted is a little bit dead grass, which is normal.

In this case, it is a lack of potassium fertilizer or a fungal infection of plants, in which case some drugs must be used, such as carbendazim chlorothalonil.

If this situation should be caused by plant fungi infection with blight, some drugs must be used, such as some methyl sulfide mixture or chlorothalonil used in blight.

1.Due to the temperature above 30 in the northern summer, it is humid and muggy, and the growth of cool-season lawns enters a dormant period. In case of rainy weather, it is necessary to ensure that the lawn is drained smoothly, and the water accumulation in individual sections should be manually removed in time.

If you notice that the tips of your turfgrass turn yellow during the summer months, it is due to the fact that you have not watered for a long time, as lawns need a lot of water.

Maybe it's too dry, right? So the leaves are withered and yellowed, right?

The yellowing of the tips of the turfgrass in summer is not a disease, it is caused by the lack of nutrients in the soil, and fertilization is sufficient.

In the summer, the grass has yellow leaves at the tip, which is a disease of premature aging, so I just spray some pesticides or eat some fertilizer.

Summer turfgrass tips yellowing downward.

This is yellowing, and you need to spray a little carbendazim.

This must be found by a professional, and this horticulturist will only know after a look, because these are some professional problems, because the specific situation is treated.

Hello, I am a farmer who grows lawns, and if the leaves are not too long in this season, it is only a lack of fertilizer! Just buy some compound fertilizer and sprinkle it.

It is very common for the lawn to turn yellow and dry. If your lawn is also experiencing this problem, then you may need some special treatment measures.

First of all, you need to check for the presence of overwatering or lack of water for the sake of the losers. Lawns need enough moisture to maintain normal growth. If you overwater it, the roots may drown and rot.

Conversely, if you don't water enough, the roots of your lawn will be shallow, which is not conducive to absorbing nutrients and water. So you need to master the amount and timing of watering.

Second, you can try using agrochemicals to treat your lawn. These drugs can speed up the growth of the lawn, improve nutrition and disease resistance. Lawn maintenance medicine can choose fertilizers and agricultural medicines, but lawn plants are also greatly affected by the environment of the Ministry of Outer Surveyabe, so we should do what we can in the use of medicines, and choose safe and environmentally friendly products.

In short, to keep your lawn in healthy condition, we need to maintain the right amount of watering and use specialized maintenance chemicals. Only in this way can long-term governance effects be achieved.

If the grass on the lawn is yellow, if it is caused by insufficient fertilizer, it is necessary to fertilize the lawn in time to supplement its nutrients. If it is caused by insufficient water, the lawn should be watered appropriately so that it can grow normally in the later stage. If it is caused by improper pruning, the later maintenance should be strengthened, and the appropriate amount of watering and fertilization can promote the growth of the grass and enable it to recover.

The yellowing of the grass on the lawn may be caused by a lack of fertilizer. During the management period, the lawn should be fertilized regularly to provide it with adequate nutrition. The fertilizer is mainly compound fertilizer, and the lawn is given sufficient thin fertilizer, which can make the grass grow better.

During fertilization, it is necessary to pay attention to the concentration and do not apply fertilizer frequently.

The yellowing of the grass on the lawn can also be caused by a lack of moisture. If the lawn is short of water, it is necessary to water the lawn in time to replenish the moisture. During the curing period, water the soil in moderation to keep the soil moist.

When watering the lawn, it is necessary to control the amount of watering, if there is too much water, it will hurt the root system of the grass and affect the growth of the grass.

When mowing the lawn, if it is cut too short, it will also turn yellow later. If it is caused by too short mowing, it is necessary to strengthen management, water and fertilize the lawn in the right amount to make it grow quickly. In the later management, it is necessary to prune appropriately, and the length of the pruning should not exceed one-third of the grass, otherwise it will affect the appearance and make the grass yellow.

The yellowing of the grass on the lawn may be caused by pests and diseases. Improper maintenance methods will affect the growth of grass and make it vulnerable to pests and diseases. After the lawn is infested by pests and diseases, it can be sprayed with relevant chemicals to remove insects.

In the later stage, it is necessary to water and fertilize reasonably, and during the maintenance period, it should be sprayed regularly to prevent pests and diseases.

If the sowing time is not long, it may be that the pioneer grass seed sowing is unreasonable; Something went wrong with the preparations.

Generally speaking, we do turf planting according to the climatic characteristics and soil conditions to select the main grass species, and carry out the mixed sowing of two turfgrass species, preferably two turfgrasses that can complement each other's advantages. The main grass species of mixed sowing is perennial turfgrass that is resistant to pruning and has a slow growth rate, and the stress resistance of mixed turf is very strong. Good for management.

Another process before mixing is the sowing of pioneer grass seeds.

The main role of pioneer grass seeds is to consolidate soil and water retention, optimize the mixed sowing environment, and maintain good soil conditions. Pioneer grass seeds should have: fast growth rate, short life span, the main grass seed begins to take shape, and the pioneer grass seed is also declining.

There's no way to start from scratch now. I suggest that you do a good job of follow-up maintenance and management, and you should be able to make progress.

1. Good water management: the water and soil conditions should not be optimal, drainage should be carried out in rainy days, and appropriate irrigation is needed if it is too dry to keep the soil warm and moist.

2. Pay attention to the soil changes: once the compaction is found, punch the hole in time.

3. According to the observation of turfgrass growth and coverage, determine whether to reseed.

4. Now fertilization should be done in small quantities and many times, and a large amount of fertilizer should not be applied at one time.
