50% use of cotton on top of the wettable powder

The protruding selling point of the product:

It can lead to the production of abscisic acid, leaves and petioles naturally fall off, defoliation is complete, and will not be polluted by dry detritus, making artificial cotton production and machine mining more convenient, so that the quality of cotton is higher.

Protection of top peaches can promote cracking of top peach and increase yield.

After use, the cotton can be white, long fiber and full of cotton seeds, and the quality and yield of cotton can be improved.

The use of crop fields can improve the ventilation and light translucent of the planting field, which is beneficial to the normal growth of the intercropping crops, and the cotton rod is easily drawn, and the cotton leaves can also increase the fertility of the soil.

The method of pesticide dosage for crop control object preparation cotton leaves 450-600 grams / ha 30-40 grams / mu.

spray

One: use time and weather:

1: when the natural spout rate of cotton is about 35% to 40%, the spray of stem and leaf with 50% TPL can effectively promote the defoliation of cotton, and it also promotes the cotton boll spout, which can improve the proportion of the flower before the frost. Spraying time should not be too early, otherwise it will affect output.

2: hand picked cotton: Northern Xinjiang at the end of August at the beginning of -9, southern Xinjiang in early September, and 25-30 grams of whole plant spray.

3: machine picking cotton: Northern Xinjiang at the end of August -9 month, in the middle of Xinjiang in the middle of September, the temperature is above 24 C and 30 g / mu, the temperature below 24 C below 30-40 g / mu. Choose a clear day to use drugs to avoid the use of cloudy and rainy days.

4: the temperature changes after the treatment, the lowest temperature of the day after medication is more than 12 degrees centigrade and 3-5 days in a continuous period, which is beneficial to the good play of this product, and must avoid the strong cooling weather within 1 weeks.

5: Cotton density is less than 13 thousand plants / mu, maturity is good, can use low dose, otherwise high dose.

6: mechanical or artificial use of Mu water consumption of 30-50 liters, aircraft spraying Mu water consumption of 6-8 liters, full field leaf spray.

7: at least 12 days before the harvest.

Two: mixed with Ethephon:

In general, 40% ethephon 3 kg / ha plus 50% th, 450 g / ha. For cotton fields with weak growth and even premature decay trend, 40% ethephon 2.25 kg / ha plus 50% ppl 300 g / ha. Three: factors affecting the play of the group:

1: temperature and humidity: high temperature and high humidity, cotton plant metabolism, defoliation fast; low temperature drying, slow metabolism of cotton plant, slow defoliation speed, poor effect; lower than 12 degrees, cotton physiological metabolism is inhibited, cold shock, defoliant at this temperature does not produce any physiological effect.

2: cotton maturity: when the cotton plant has been naturally aging, the bell is uniform and the vegetative growth is significantly weakened, it is easy to defoliate.

3: cotton varieties: early maturity and high yield cotton are beneficial to the development of 50% ticbar.

4: nitrogen level: if the cotton still maintains too much nitrogen in the late growth period, the growth of the plant does not stop, the cotton plant physiology does not enter the mature period, which will increase the risk of the defoliation difficulty and produce the dry leaf; the cotton plant should plan to use the nitrogen content so that the nitrogen of the cotton field at the end of the growth is basically used out, and the best nitrogen application will be used after 10 days of nitrogen application.

5: Irrigation: irrigation water management is crucial to the health of cotton plants. If cotton is short of water during its growth and development, it will not reach its potential yield. However, excessive irrigation will affect the effect of defoliation. The final time of irrigation can not only meet the needs of the growth and maturity of cotton bolls, but also avoid the greedy and late ripening of cotton plants with high soil water content in the later period. With the decrease of soil nutrients, the timely water stop (about 10 days before the drug use) can slow the growth of nutrition, promote the synthesis of mature hormone and be beneficial to the defoliation of cotton.
