Rice green blight is a physiological disease, before the onset of the disease, the disease, the healthy plant is not different, often occurring in large areas of 1-2 days, manifested as a sudden death of the whole hole,

Rice green blight prevention and control methods: (1) selection of drought-resistant varieties, generally more drought-resistant than the japonica rice, precocious, large spikes less tiller type varieties are more resistant to drought. (2) The late management of paddy fields should be combined with shallow water and open fields, and water should not be cut off too early, especially in sandy soil and leaky fields. Avoid long-term deep irrigation, timely and moderate shelving, and promote root growth. (3) Reasonable fertilization, the base fertilizer should be applied sufficiently, the fertilizer should be applied early, to avoid applying too much nitrogen, too late, to prevent greening or early decline. (4) advocate the application of multi-functional high-efficiency liquid fertilizer - Wanjia Bao, in the rice spike spraying Wanjia Bao liquid fertilizer 500 times liquid, 15 days after another spray

(5) pharmaceutical control. You can use 15% Likujin, 100 grams of agent per mu of rice field, 50-60 kg of water, sprayed twice after three o'clock in the afternoon on a sunny day, at an interval of 7 days, the effect is better; or 65% of Dixon wettable powder 1.5 kg, or 2 kg of carbendazim in 60 kg of water to spray or watering.

The occurrence of blue blight, mainly due to low-temperature cold damage, cold after the storm or too large a temperature difference, such as in the rice seedling field before the uncovering of the timely ventilation refining seedlings, resulting in seedling futile, uncovering, seedlings can not adapt to the environment, resulting in the seedling body water supply imbalance, which in turn caused the above ground part of the rapid loss of water and withered,

There is also a windy weather, cloudy weather conditions still adhere to the ventilation The fact that you can't get a good deal on the price of your own personalized products and services is a good thing.

It's just that

Mr. Shi is right,

I mean the seedling disease healthy plants!

After transplanting, there is a sharp windy and cooling weather, which can trigger green blight

For Mr. Ishi's information only

That's the reason I analyzed at the top!

Thanks so much for talking with Mr. Shi
