Weed control

Peanut Science 1 January ; 46 1 : 56— Organic peanut production is a high-risk cropping system, largely due to difficulties in managing weeds using methods acceptable for certified-organic production. In contrast with conventional peanut production that relies heavily on synthetic herbicides, organic peanut production must use an integrated system to manage weeds. The foundation for an integrated weed management system is cultural weed control which is a system of production practices that promote uniform peanut growth to suppress weeds. Cultural weed control includes practices that promote vigorous early-season peanut growth and lessen chances for weed escapes.

Weed control is the botanical component of pest control , which attempts to stop weeds , especially noxious weeds , from competing with desired flora and fauna including domesticated plants and livestock , and in natural settings preventing non native species competing with native species. Weed control is important in agriculture. Methods include hand cultivation with hoes , powered cultivation with cultivators , smothering with mulch , lethal wilting with high heat, burning , and chemical control with herbicides weed killers. Weeds compete with productive crops or pasture, they can be poisonous, distasteful, produce burrs, thorns or otherwise interfere with the use and management of desirable plants by contaminating harvests or interfering with livestock. Weeds compete with crops for space, nutrients , water and light. Smaller, slower growing seedlings are more susceptible than those that are larger and more vigorous. Onions are one of the most vulnerable, because they are slow to germinate and produce slender, upright stems [ citation needed ].

Khakwani 1. Bukhari 4. The experiment was laid out in a randomized complete block design RCBD with split-plot arrangements having three replications. The main plot was comprised application time of herbicides while the use of herbicides was assigned to sub-plots. The data revealed that most of the weed parameters, physiological traits and agronomic attributes of crop plants were significantly affected by weed management practices including the use of herbicides at different time intervals over the weedy check. Hand weeding technique excelled all other weed management practices in almost all the parameters studied.

Information is available for identifying species, the best methods of control and management of these pests, biocontrols and how the responsibilities for managing these pests are shared. There are many plants and animals in the Tasman region that are considered undesirable.

Herbicide Resistant Weeds: The Technology and Weed Management

Weed , general term for any plant growing where it is not wanted. Ever since humans first attempted the cultivation of plants, they have had to fight the invasion by weeds into areas chosen for crops. Some unwanted plants later were found to have virtues not originally suspected and so were removed from the category of weeds and taken under cultivation.

Weed Management

Scientists have theorized that weed management would be more efficient if prevention tactics were integrated with control tactics. The goals of prevention are to reduce weed community density and improve crop tolerance to weeds. Here we describe the impact of this approach in the semiarid steppe of the United States. Critical factors for success with this approach are rotation design and no-till practices. Rotations comprised of two cool-season crops followed by two warm-season crops are the most disruptive of weed population growth. The impact of rotation design on weed community density is enhanced by no-till. Crop tolerance to weeds is improved by systems of cultural tactics.

Но затем я сделал несколько тестов и обнаружил… - Он остановился, вдруг почувствовав себя не в своей тарелке.  - Я обнаружил, что кто-то обошел систему фильтров вручную. Эти слова были встречены полным молчанием. Лицо Стратмора из багрового стало пунцовым.

Сегодня же суббота. Найди себе какого-нибудь парня да развлекись с ним как следует.

Стратмор посмотрел на ее залитое слезами лицо, и ему показалось, что вся она засветилась в сиянии дневного света. Ангел, подумал. Ему захотелось увидеть ее глаза, он надеялся найти в них избавление.

Беккер рассеянно кивнул: - Хорошо. Бело-красно-синие волосы, майка, серьга с черепом в ухе. Что. - Больше .

 Черт! - Фонтейн снова схватил трубку и набрал номер мобильника Стратмора. На этот раз послышались длинные гудки. Фонтейн насчитал уже шесть гудков. Бринкерхофф и Мидж смотрели, как он нервно шагает по комнате, волоча за собой телефонный провод. Директор АНБ напоминал тигра на привязи.

Третий узел был пуст, свет шел от работающих мониторов. Их синеватое свечение придавало находящимся предметам какую-то призрачную расплывчатость. Она повернулась к Стратмору, оставшемуся за дверью.

Такая архитектура стала популярной в те времена, когда церкви одновременно служили и крепостями, защищавшими от вторжения мавров, поскольку одну дверь легче забаррикадировать. Теперь у нее была другая функция: любой турист, входящий в собор, должен купить билет. Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме.

Беккер огляделся: - Понимаю. Это ужасно. Простите, что я так долго до вас добирался. - Мне даже не сказали, что вы придете. Беккер поспешил переменить тему: - У вас на голове огромная шишка.

Он вытирал лоб простыней. - Простите… может быть, завтра… - Его явно мутило. - Мистер Клушар, очень важно, чтобы вы вспомнили это.  - Внезапно Беккер понял, что говорит чересчур громко. Люди на соседних койках приподнялись и внимательно наблюдали за происходящим.

    Pest resistance to control methods in general is not an isolated phenomenon but usually expected and well demonstrated when any method is repeatedly applied over a long period of time without being changed or modified in nature, structure, principals of application or formulation.
