What You Need to Know About Pesticide Use on the Farm

Pesticides serve many functions and come in many forms,including herbicides,杀虫剂,以及杀菌剂。在所有情况下,最终目标都是通过减少竞争环境因素来提高作物产量。

Weeds,bugs,疾病夺走了植物的健康和营养,降低生产力。Pesticides can help,如果使用得当。

Applying herbicides for weed control

Herbicides reduce weed competition.市场上的产品种类繁多。麦草畏是最流行的除草剂之一。麦草畏通过提高植物的生长速度来杀死一年生和多年生阔叶杂草,直到其营养物质供应不足并死亡。

随着孟山都公司的转基因抗麦草畏植物的引进,麦草畏的使用也增加了。

人们已经知道,旧的除草剂配方会造成向其他植物漂移的问题。Newer,less drift prone versions are now available.New EPA-approved labels for the 2019-2020 growing seasons offer revised instructions for use.

申请迪坎巴时,农民可以采取措施提高效率和减少环境影响,beginning with selecting the right product for the right crop.For Round-up Ready soybeans,use only approved formulas,and make sure the applicator is properly certified.大多数州的推广服务机构每年都会提供必要的杀虫剂喷洒器培训。

随着新的标签来调整风向限制和缓冲要求。Be sure the wind is blowing in the opposite direction of any nearby sensitive crops,and keep at least a one-half mile buffer between those crops and where you are spraying.Also beware protected species buffer requirements.注意时间安排。Dicamba can be volatile for up to three days,风可以改变和阵风。

迪卡巴的申请有时间限制。标签上注明产品应在日出后一小时内使用,日落前两小时内使用,此时温度倒转的可能性较小。

确保使用正确的应用设备,并检查产品信息,了解可接受的添加剂和罐混合伙伴。

一些农民选择在春天播种前,先施用一种燃耗除草剂。这对于免耕种植尤为重要。Most products have plantback restrictions of 7-30 days.一些燃耗除草剂有残留活性,killing plants that overwinter crop pests such as the soybean cyst nematode.

如何管理帕尔默苋菜

尽管农业科学界寻求管理大自然,她经常有其他想法。Anew challenge to farmers appearing in recent yearsis palmer amaranth.The weed can grow 10 feet tall,有和棒球棒一样粗的球茎,and if tossed into a field,可以重新启动自身。普渡大学的研究表明,由于虫害,大豆产量下降了78%。玉米91%。

Palmer amaranth grows quickly,making timely herbicide treatment crucial.其他措施,such as reducing soybean row width,keeping the plants from going to seed,and planting cover crops can help reduce the pest's impact.

Palmer amaranth is on the move from the South into the Midwest and scientists at Kansas State University已证实有多种抗麦草畏和2,4-D。The Group 4 products have worked in the past,但近几年来效果不佳。这项研究正在进行中。

如何管理水麻

Waterhemp is another unwanted plant that can do serious damage to yields.University of Missouri researchers have now identified a population with resistance to six herbicides.Dicamba and glufosinate were the only two of eight herbicides applied that produced weed control.

Experts recommend a混合的生物,机械的,以及攻击杂草的文化措施。识别,timely treatment,layering herbicides,种植更窄的行,使用新技术,all while keeping an eye on other weeds may help.

Herbicide resistant waterhemp has also been identified in Illinois,the first broadleaf species to show Group 15 resistance.

科学家们把这种抵抗归因于进化。传统上,农民使用的是出苗前残留的除草剂,but nowexperts are rethinking the year-over-year practice and the changes in plant biology结果。

Using insecticides

抗性也是昆虫控制的一个问题。Cornrootworms adapt to control programs,including hybrid corn varietiesdeveloped with pest control in mind.幸运的是,根虫不会走很远,and resistance is often contained to the field where it developed.

轮作作物会有帮助;even a one-year soybean break can disrupt the rootworm life cycle and lower population density.一些人发现使用杀成虫的叶面杀虫剂有帮助,但产品越来越受到限制。

New insecticides are in the development stage,but it may be some time before they hit the market.

玉米的Bt性状对根虫的防治效果可能不如根虫感染前。但是科学确实可以防止欧洲玉米螟(EBC)。Near eradication of the pest has caused some farmers to plant hybrids without corn borer protection.

For those wanting to use less expensive seed,欧洲央行可以通过其他方式进行控制,但战场需要勤勉的侦察和立即采取行动。

杀菌剂

安全有效地使用杀菌剂,like any other pest control product,requires strict adherence to label directions.There are various classes of fungicides,有些是有疗效的,有些是预防性的。All work best before disease is present by preventing spores from germinating.

再一次,ardent scouting and timing are crucial.

Beware pesticide drift

安全的杀虫剂应用还包括对农药漂移的认识。如果产品走入歧途,你和你的邻居都会受到伤害。Not only can yields be reduced,但在某些情况下,申请者可能要承担法律责任。

Pesticide drifting to unsuspecting plants in the crossfire can cause environmental damage,包括破坏传粉者和野生动物栖息地。所以,确保使用正确的产品,at the right time,有了合适的设备,under the right betwayapp下载weather conditions.Generally you will want wind speeds of less than 10 mph.

和你的保险代理人谈谈coverage against damage to yours or your neighbor's crops.了解你的覆盖范围和限制。

一直以来,always,always treat any pesticide with the utmost care.Used incorrectly,they can become an environmental hazard.Used correctly,they can protect your crop and your farm's profitability.
