4 million acres of wheat fields with dead seedlings? Beware of grubs erupting again! How can farmers prevent it?

author:Learn to farm every day

To this day, many wheat farmers in Shaanxi still have lingering feelings. In 2019, more than 4 million mu of wheat fields in Xianyang, Baoji, Weinan and other places saw dead seedlings, the biggest reason for which was the large outbreak of grubs and the failure of farmers to prevent and control them.

grubs

Grub grub, commonly known as "silkworm" or "chicken mother worm", is the larva of the scarab beetle or golden turtle shell, and autumn is the peak of its harm. Grubs mainly harm the wheat root system, resulting in yellowing of the leaves of the affected plants, few tillers, and short plants, once the roots are seriously endangered, the plant will gradually wither and die, and after being pulled out, the main root will be found to have been bitten to death.

Since grubs are underground pests, we must adhere to the plant protection policy of "prevention first, comprehensive prevention" and focus on prevention. No matter what year wheat is planted, you can't let your guard down. Farmer friends here will ask, so how to prevent it? In addition to agricultural measures such as crop rotation, deep ploughing and drying of the soil, the key is to coat the wheat seeds.

The principle of wheat seed coating is that the agent solidifies on the surface of the seed into a film to form a seed coat, just like putting a protective suit on the seed. Because the high-quality seed coating agent has a relatively long shelf life, its medicinal effect will continue to be released, and the underground pests and the ground stinging pests will be poisoned and die after feeding.

So what are the high-quality seed coating agents? Syngenta's Kuras is one of them. Jia Shaofeng, manager of the technology of The Plant Protection Development Department of Syngenta (China), mentioned in "Brilliant Farmers" that the use of Syngenta's Kuras seed coating agent can coat wheat seeds 20-30 days in advance. There are five main advantages: 1. High safety factor; 2. Good effect on disease and pest prevention, good effect on golden needle worm, scattered smut disease and other diseases and insect pests; 3. The effect of strong seedlings is outstanding, the root system is developed, and tillering is increased; 4. Xianzhengda advanced production technology, quality control; 5. In line with the national "pesticide zero growth" green plan.

Some farmers may ask, is it really so powerful? Then let's use the test to tell you the answer. The experiment was carried out using Syngenta's Coolas Seed Coating Agent.

We can see that there is a clear dividing line between the control and the Kulas treatment, just as The Kulas has built a stable protective wall for wheat. The phenomenon of severe ridge breaking of the control seedlings is very serious, and the wheat treated by Kuras is lush, lush and green and robust.

This is a trial done in a dryland in 2019, when grubs were particularly severe. However, in the case of the same conditions of water and fertilizer, variety and sowing amount, the customer's exploration found that Kuras can effectively control grub infestation and make wheat seedlings grow robustly.

After looking at the field performance, let's look at the comparison of details. Also 10 wheat seedlings were selected, and the wheat seedlings coated by Kuras had a large amount of roots, a long root system, many fine roots, and the growth of wheat seedlings in the upper part of the ground was better than that of the control.

Also 10 wheat seedlings were selected, and the leaves of the kuras-coated wheat seedlings were more green than those of the control treatment. Only 1 of the 10 medium-kulas-coated wheat seedlings had initial infestation disease, which was much less than the number of control initially infected plants. The Kuras-coated wheat seedlings have more roots, more well-developed roots and more capillaries than the control roots.

Let's take a look at the enlarged wheat root system, the wheat root system treated by the control is simply weak in front of Kuras, the root system is very weak, thin and small. It is conceivable that such a root system can better absorb the nutrients in the soil, and how can the yield and quality of wheat be improved in the later period?

Finally, to sum up: wheat yield increase and yield, starting with Kuras coating!
