When cotton aphids (especially Fuxi) occur, urea, washing powder and water are mixed in a ratio of 4:1:400 per acre to prepare a "salt mixture" spray, which has obvious killing. Insect effect.(cheap plastic plant pots wholesale supplier ireland)
Spraying in the flowering and ringing period can prevent bell disease and reduce rotten bells(propagation tray). 1 part of copper sulphate, 1 part of lime, 200 parts of water, prepared into an equal amount of Bordeaux mixture, sprayed at the seedling stage of cotton, can control cotton seedling diseases. Use 10 kg of plant ash, 50 kg of water, soak for 24 hours, filter, take the filtrate spray, can effectively kill the mites on cotton(greenhouse supplies pots).

(cheap plastic plant pots wholesale supplier ireland)Generally, potassium fertilizer is mainly used, and compound fertilizer with low nitrogen content is applied, and it is applied from mid-July to mid-August(black plastic plant pots). To meet the needs of crop growth and development, but also to control a variety of pests and diseases. Nitrogen fertilizer can be used to treat aphids(plastic grow pots). The compound fertilizer and phosphate fertilizer with low nitrogen content were mainly applied, and most of the new shoots were applied at the end of May.
For every 1000 kg of flue-cured tobacco leaves, nitrogen (N) 22 kg, phosphorus (P2O5) 11.6 kg, and potassium (K2O) 48 kg are required(plastic nursery pots wholesale).

Most of the nutrients needed for many crops are obtained from soil. However, in recent years, the irrationality of soil cultivation, the unscientific fertilization, and the environment The seriousness of the damage has led to a decline in soil fertility and a lower and lower agricultural production(200 cell seed starter trays). In the cotton bud period, 50-75 kg of 50 ppm chlormequat solution is sprayed on the cotton field with verticillium wilt.
