What pesticides work well for growing foxtail millet?
Foxtail millet is a plant of the grass family. In ancient times it was called ji or su, and it is actually unhulled millet. This crop has a very long history in our country and is one of the traditional five grains; it was already found in Neolithic cultural sites from six or seven thousand years ago. So in today's extremely advanced science and technology, what pesticides need to be used during the growth of foxtail millet?
1. Herbicide pesticides for foxtail millet
During the growth of foxtail millet, pesticides are generally needed only when weeding and controlling pests and diseases. The main herbicides used are 50% prometryn, linuron, 44% monosulfuron·prometryn, etc., while the pesticides used in pest and disease control include triadimefon wettable powder, thiodiazole-copper suspension concentrate, mancozeb and cypermethrin emulsifiable concentrate, carbofuran, carbendazim wettable powder, etc.
Prometryn mainly targets grass-family weeds such as crabgrass, foxtail, and barnyardgrass, as well as many broadleaf weeds such as lambsquarters, amaranth, ducktongue grass, and pondweed. The method of use is 50g per mu mixed with 40-50kg of water and sprayed on the soil surface. Linuron mainly controls some annual grass-family weeds and many broadleaf weeds; the method of use is 400-500g per mu mixed with 40-50kg of water
and sprayed. 44% monosulfuron·prometryn targets broadleaf weeds and monocotyledonous weeds; the method of use is 52.8-70.4g per mu mixed with 40-50kg of water and sprayed.
2. Pesticides for pest and disease control of foxtail millet
The main diseases of foxtail millet include foxtail millet downy mildew, foxtail millet rust, foxtail millet blast, foxtail millet leaf spot, and foxtail millet brown stripe disease, etc.
For foxtail millet leaf spot, at the early stage of the disease, spray 36% thiophanate-methyl suspension concentrate at 500-600 times dilution or 50% carbendazim wettable powder at 600-800 times dilution, or 30% basic copper sulfate suspension concentrate at 400 times dilution, spraying once about every 10 days, for 2-3 consecutive treatments. Foxtail millet downy mildew is called hedgehog head. Use 50% carbendazim wettable powder at 600-800 times dilution and spray before heading and after flowering for control.
For foxtail millet rust, 15% triadimefon wettable powder at 600 times dilution can be used for the first spraying. After 7-10 days, a second spraying may be carried out as appropriate. For foxtail millet blast, at the early stage of the disease, spray the field with 65% mancozeb at 500-600 times dilution, or thiophanate-methyl at 200-300 times dilution on the leaf surface for control.
When foxtail millet brown stripe disease occurs, 72% agricultural streptomycin or 20% thiodiazole-copper suspension concentrate can be sprayed on the leaves, once every 7 days, preferably 2-3 times in a row. For plots with severe disease, remove old leaves, remove ineffective stems and overly dense and poorly growing plants, improve ventilation, and lower the temperature.
The main pests of foxtail millet include mole crickets, wireworms, stem borers (millet stem borer, corn borer), millet stem flea beetles, armyworms, millet stem maggots, and several others. The degree of occurrence of these pests differs among different years, and the control measures for different pests also differ; agricultural measures are mainly used for control, but pesticides can also be used. The pesticides generally used include cypermethrin emulsifiable concentrate, carbofuran, carbendazim wettable powder, etc., and the specific use is determined according to the specific pest.
